Transparent Solar Panels: a Powerful Alternative to Glass

Transparent Solar Panels: a Powerful Alternative to Glass

In the foreseeable future, transparent solar panels hold the potential to take the place of conventional windows, although several challenges must first be overcome. Transparent solar panels are crafted from materials that permit visible light to pass through while capturing the sun’s energy to generate electricity. This unique feature grants them an aesthetically pleasing advantage over traditional, bulky, and opaque solar panels.

However, the best technologies still have lower efficiency than their traditional counterparts, resulting in lower electricity generation per square meter. Moreover, the cost exceeds that of traditional ones, making them less economically viable for the majority of consumers.

Transparent solar panels are made of a transparent material, such as titanium dioxide or amorphous silicon. These materials allow visible light to pass through while still absorbing some of the energy to generate electricity. This makes transparent solar panels more aesthetically pleasing than traditional solar panels, which can be bulky and opaque.

They are still in the early stages of development, but they have the potential to revolutionize the way we generate electricity. They could be used to power buildings, cars, and other devices without taking up any extra space. For example, transparent solar panels could be used to create solar-powered windows that would allow natural light to enter a building while also generating electricity. They could also be used to create solar-powered car roofs or windows that charge the car’s battery whenever it is exposed to sunlight.

 

They will make economic sense in larger applications despite their lower power-generating capacity. For example, a large high-rise building with good solar exposure could have all the windows facing the sun made with solar panels instead of glass. On a large surface area, this would provide a significant amount of power to run the systems in the building. When combined with high-efficiency LED lighting, regeneration from elevators, and energy storage, the building could become energy neutral or even a net producer.

 

Numerous companies are vigorously working on enhancing the efficiency and affordability of glass solar panel windows. Successful advancements in this direction could potentially position transparent solar panels as a practical alternative to traditional windows in the future.

Here are some companies actively involved in developing transparent solar panels:

  1. SolarWindow Technologies: Pioneering the field, SolarWindow Technologies has created a transparent solar panel utilizing a thin film of titanium dioxide. This material absorbs sunlight and converts it into electricity. The company claims its transparent solar panel boasts 90% transparency and has the capacity to generate up to 10 watts of electricity per square meter.
  2. PolySolar is a company that specializes in the development and manufacturing of transparent solar panels. PolySolar’s transparent solar panels are made of a thin film of cadmium telluride (CdTe), which is a semiconductor material. CdTe is a very efficient material for absorbing sunlight and converting it into electricity. PolySolar’s transparent solar panels are also very transparent, allowing up to 80% of visible light to pass through.
  3. Onyx Solar is a company that specializes in the development and manufacturing of transparent solar panels. Onyx Solar’s transparent solar panels are made of a thin film of amorphous silicon (a-Si), which is a semiconductor material. a-Si is a very transparent material, allowing up to 80% of visible light to pass through.

These companies represent just a glimpse of the ongoing efforts to develop solar panel windows. With continued research and development, it remains promising that glass solar panels will eventually emerge as a compelling option for replacing windows in the future.

Milk & More to trial doorstep deliveries of refilled Coca-Cola

Milk & More to trial doorstep deliveries of refilled Coca-Cola

From next Monday (5 June), Milk & More customers in South London and some parts of the South will be able to buy one-litre bottles of Coke Zero which they will then be instructed to rinse and leave on their doorstep for collection.

The collected bottles will be sent off for washing and refilling; they can be refilled up to 20 times before they need to be recycled.

Milk & More already offers reusable glass bottles for several of its own-brand lines including milk, water, fruit juices and soft drinks. In total, it delivers 80 million refillable bottles each year already.

Milk & More’s chief executive Patrick Muller said: “Our customers want to be more sustainable, but they are busy people and need simple solutions to help them, so we are confident that they will welcome this trial as it offers them exactly the same service as they already have with Milk & More.”

The business is working with Europe’s largest Coca-Cola bottler, CCEP, on the new trial. It will run for a minimum of eight weeks and the hope is to reach 100,000 customers.

CCEP’s senior sustainability manager Jo Padwick said the trials will allow for the gathering of “valuable insights into how consumers respond to return-based trials in comparison to recycling”.

The Coca-Cola Company, globally, is notably aiming for 25% of its beverage sales to be housed in reusable or returnable packaging by 2030. It announced this target last year.

The Milk & More trials are being touted as the only way, at present, for UK-based customers to receive refillable Coca-Cola to their homes.

Pre-filled reusable Coca-Cola Company products have previously been offered via Tesco and Terracycle, under the Loop scheme. However, Tesco stopped offering Loop services last July.
