Enhancing quantum dot solar cell efficiency to 11.53%

A novel technology that can improve the efficiency of quantum dot solar cells to 11.53% has been unveiled. Published in the February 2020 issue of Advanced Energy Materials, it has been evaluated as a study that solved the ...

Black silicon photodetector breaks the 100% efficiency limit

Aalto University researchers have developed a black silicon photodetector that has reached above 130% efficiency. Thus, for the first time, a photovoltaic device has exceeded the 100% limit, which has earlier been considered ...

Directivity to improve optical devices

A team of researchers from the Dutch institute AMOLF, Western University (Canada), and the University of Texas (United States of America) recently demonstrated the use of algorithmic design to create a new type of nanophotonic ...

Low-cost 'solar absorber' promising for future power plants

Researchers have shown how to modify commercially available silicon wafers into a structure that efficiently absorbs solar energy and withstands the high temperatures needed for "concentrated solar power" plants that might ...
