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

Posted on May 24, 2023May 24, 2023 by dishanth

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.

Quantum battery breakthrough paves way for revolution in energy storage

Posted on January 20, 2022 by dishanth

Researchers have made significant progress towards making quantum batteries a reality after demonstrating a new proof-of-concept device.

The next-generation battery technology has the potential to revolutionise energy storage by making use of a phenomenon known as superabsorption.

This process involves a quantum mechanical principle relating to a molecule’s ability to absorb light, requiring less charging time the more they become entwined.

This means that it is theoretically possible for the charging power of a quantum battery to increase faster than the size of the battery. Superabsorption therefore means the bigger the battery, the faster it charges.

Until now, however, it has not been possible to demonstrate the effect on a large enough scale to make a quantum battery.

In a new study, published in the journal Science Advances, researchers at the University of Adelaide in Australia were finally able to prove the concept of superabsorption by building several wafer-like microcavities, filling them with organic molecules, and charging them with a laser.

“As the microcavity size increased and the number of molecules increased, the charging time decreased,” said Dr James Quach, a scientist at the Institute for Photonics and Advanced Sensing at the University of Adelaide.

“This is a significant breakthrough, and marks a major milestone in the development of the quantum battery.”

The next step is to now develop a fully functioning quantum battery prototype, with the hope of ushering in a new era of ultra-efficient batteries for use in electric vehicles and electronic devices.

The way quantum batteries operate means they could potentially harvest and store light energy simultaneously, providing significant cost reductions compared to conventional solar technologies.

“The concepts that Dr Quach and his team have worked on opens up the possibility of a new class of compact and powerful energy storing devices,” said Professor Peter Veitch, head of the University of Adelaide’s School of Physical Sciences.
