New records in perovskite-silicon tandem solar cells through improved light management

14. 11. 2018 | Tech Xplore | www.techxplore.com

Using microstructured layers, an HZB team has been able to increase the efficiency of perovskite-silicon tandem solar cells, achieving 25.5 percent, which is the highest published value to date.

The team used computational simulations to investigate light conversion in various device designs with different nanostructured surfaces. This enabled optimization of light management and detailed energy yield analyses. The study has now been published in Energy & Environmental Science.

New solar cell record efficiency

Tandem solar cells made of silicon and metal halide perovskite compounds can convert a particularly large portion of the solar spectrum into electrical energy. However, part of the light is reflected and is thus lost for purposes of energy conversion. Using nanostructures, the reflection can be reduced significantly ensuring that the solar cell captures more light.
