Solar panel efficiency to increase 50% with “miracle” cells

Solar panel efficiency to increase 50% with “miracle” cells

A South Korean company has made a groundbreaking achievement as they unveiled the world’s first production line dedicated to perovskite-silicon tandem solar cells. These innovative solar cells have the potential to boost efficiency by 50-75% compared to standard solar panels.

The commercialization of perovskite-based solar cells marks a significant milestone after years of advancements with the mineral. It has widely been regarded as a “miracle” material capable of revolutionizing various industries, including renewable energy.

The next-generation solar cell technology

Qcells, based in Seoul, has committed a substantial investment of US$100mn to bring this next-generation solar cell technology from the realm of lab tests and academic research to practical application.

A pilot production line to be operational by late next year will be funded by the investment at a factory in Jincheon.

“This investment in Jincheon will mark an important step in securing technological leadership,” said Justin Lee, CEO of Qcells.“With a global R&D network spanning from Korea, Germany and the US, Qcells will ramp up its efforts to produce high-efficiency advanced tandem cells.”

 

Improving sufficiency

Tandem solar cells offer a significant enhancement to the efficiency of conventional solar panels, by dividing the light spectrum and optimizing energy extraction from each segment to generate electricity.

In fact, the world record for solar cell efficiency stands at 32.5%, achieved with a perovskite-silicon tandem cell. In contrast, traditional silicon-based solar cells typically reach only around 22% efficiency.

This signifies that nearly one-third of solar radiation can be efficiently converted into electrical energy.

The development of tandem solar cells represents a promising leap forward in harnessing solar energy more effectively and surpassing the limitations of conventional silicon-based technologies.

Samsung pledges to become carbon neutral by 2050

Samsung pledges to become carbon neutral by 2050

Samsung has made a commitment to achieve net zero carbon emissions for the whole company by 2050 and will spend US$5bn to do so
South Korea’s Samsung Electronics has announced an environmental strategy to achieve net zero carbon emissions by 2050.

The company intends to spend more than KRW7tn (US$5bn) over the next seven and a half years to achieve that goal. This money will go towards reducing process gases, conserving water, expanding electronic waste collection and reducing pollutants.

By reaching net zero direct and indirect carbon emissions, Samsung Electronics expects to reduce the equivalent of about 17 million tons of carbon dioxide-equivalent (CO2e) emissions based on 2021 figures.

“The climate crisis is one of the greatest challenges of our time. The consequences of inaction are unimaginable and require the contribution of every one of us, including businesses and governments. Samsung is responding to the threats of climate change with a comprehensive plan that includes reducing emissions, new sustainability practices and the development of innovative technologies and products that are better for our planet,” said Jong-Hee Han, Vice Chairman and CEO of Samsung Electronics.

 

 

Developing technologies for a better planet
The company plans to develop new technologies to reduce process gases — a byproduct of semiconductor manufacturing — and install treatment facilities on its semiconductor manufacturing lines by 2030.

Samsung Electronics has also joined RE100, in an effort to reduce indirect carbon emissions from power consumption, and aims to match electric power needs with renewable energy by 2050 for all operations globally.

The company will implement low-power technologies in major models of seven consumer electronics products — smartphones, refrigerators, washing machines, air conditioners, TVs, monitors and PCs, with the goal of lowering power consumption levels by an average of 30% in 2030 compared to products with the same specifications in 2019.

To ensure accountability, Samsung Electronics will have its efforts objectively verified by designated organisations. Its performance will be assessed via participation in the Samsung Institute of EHS Strategy’s certification system and verified by a Carbon Reduction Verification Committee that includes third-party experts.

Southeast Asia’s $200+ Billion Renewables Opportunity

Southeast Asia’s $200+ Billion Renewables Opportunity

There is a $205-billion opportunity in renewable energy for Southeast Asia from which China, Japan, and South Korea could benefit as the biggest energy lenders to smaller countries in the region, Greenpeace has said in a new report.

“These three East Asian countries are top global energy investors, with established ties in Southeast Asia. But coal finance is drying up and banks are struggling to get a grip on clean energy finance. The climate crisis depends heavily on the flexibility and ingenuity of East Asian finance. And state-backed public development banks once again need to play the trailblazer role to engage new markets,” according to Insung Lee, project manager of Greenpeace Japan’s climate and energy team.

Southeast Asian countries, according to the report, will need investments of some $125.1 billion for solar energy over the next ten years, as well as $48.1 billion for wind energy, assuming they want to pursue the renewable energy path instead of sticking to fossil fuels. And China, Japan, and South Korea are in a position to convince them to choose the renewable energy path by investing in solar and wind rather than fossil fuels.

However, the report notes that the three East Asian powerhouses are also large exporters of coal infrastructure and lenders for coal power plants to their neighbors in Southeast Asia. This has to change if they are to reap the benefits of the nascent renewable energy financing market in the region, the report says.

“East Asian finance will be as important for renewable energy in Southeast Asia as it was for coal. Over the past two decades, we’ve seen East Asian banks skew the margins towards coal to keep the fossil fuel profitable despite ballooning financial risk. Over the next decade, we’ll see them apply the same ingenuity to unlock renewable energy from the restrictions of their own financial framework,” Greenpeace Japan’s Lee also said.

Super-charged: How Australia’s biggest renewables project will change the energy game

Super-charged: How Australia’s biggest renewables project will change the energy game

Australia doesn’t yet export renewable energy. But the writing is on the wall: demand for Australia’s fossil fuel exports is likely to dwindle soon, and we must replace it at massive scale.

The proposed Asian Renewable Energy Hub (AREH) will be a huge step forward. It would eventually comprise 26,000 megawatts (MW) of wind and solar energy, generated in Western Australia’s Pilbara region. Once complete, it would be Australia’s biggest renewable energy development, and potentially the largest of its type in the world.

Late last week, the federal government granted AREH “major project” status, meaning it will be fast-tracked through the approvals process. And in another significant step, the WA government this month gave environmental approval for the project’s first stage.

The mega-venture still faces sizeable challenges. But it promises to be a game-changer for Australia’s lucrative energy export business and will reshape the local renewables sector.

 

The projects promise enormous clean development opportunities for Australia’s north and will create thousands of jobs in Australia – especially in high-tech manufacturing.

 

Writing on the wall

Australia’s coal and gas exports have been growing for decades, and in 2019-20 reached almost A$110 billion. Much of this energy has fuelled Asia’s rapid growth. However, in recent weeks, two of Australia’s largest Asian energy markets announced big moves away from fossil fuels.

China adopted a target of net-zero greenhouse emissions by 2060. Japan will retire its fleet of old coal-fired generation by 2030, and will introduce legally binding targets to reach net-zero emissions by 2050.

There are signs other Asian nations are also moving. Singapore has weak climate targets, but on Monday inked a deal with Australia to cooperate on low-emissions technologies.

 

Export evolution

The Asian Renewable Energy Hub (AREH) would be built across 6,500 square kilometres in the East Pilbara. The first stage involves a 10,000MW wind farm plus 5,000MW of solar generation – which the federal government says would make it the world’s largest wind and solar electricity plant.

The first stage would be capable of generating 100 terawatt-hours of renewable electricity each year. That equates to about 40 per cent of Australia’s total electricity generation in 2019. AREH recently expanded its longer term plans to 26,000MW.

The project is backed by a consortium of global renewables developers. Most energy from AREH will be used to produce green hydrogen and ammonia to be used both domestically, and for shipping to export markets. Some energy from AREH will also be exported as electricity, carried by an undersea electrical cable.

Another Australian project is also seeking to export renewable power to Asia. The 10-gigawatt Sun Cable project, backed by tech entrepreneur Mike Cannon-Brookes, involves a solar farm across 15,000 hectares near Tennant Creek, in the Northern Territory. Power generated will supply Darwin and be exported to Singapore via a 3,800km electrical cable along the sea floor.

The export markets for both AREH and Sun Cable are there. For example, both South Korea and Japan have indicated strong interest in Australia’s green hydrogen to decarbonise their economies and secure energy supplies.

But we should not underestimate the obstacles standing in the way of the projects. Both will require massive investment. Sun Cable, for example, will cost an estimated A$20 billion to build. The Asian Renewable Energy Hub will reportedly require as much as A$50 billion.

The projects are also at the cutting edge of technology, in terms of the assembly of the solar array, the wind turbines and batteries. Transport of hydrogen by ship is still at the pilot stage, and commercially unproven. And the projects must navigate complex approvals and regulatory processes, in both Australia and Asia.

But the projects have good strategic leadership, and a clear mission to put Australian green energy exports on the map.

 

Shifting winds

Together, the AREH and Sun Cable projects do not yet make a trend. But they clearly indicate a shift in mindset on the part of investors.

The projects promise enormous clean development opportunities for Australia’s north, and will create thousands of jobs in Australia – especially in high-tech manufacturing. As we look to rebuild the economy after the Covid-19 pandemic, such stimulus will be key. All up, AREH is expected to support more than 20,000 jobs during a decade of construction, and 3,000 jobs when fully operating.

To make smart policies and investments, the federal government must have a clear view of the future global economy. Patterns of energy consumption in Asia are shifting away from fossil fuels, and Australia’s exports must move with them.
