All-perovskite two-terminal tandem solar cell tech with 32.3% efficiency


Indian scientists have designed a new all-perovskite tandem solar cell configuration that can reportedly achieve higher efficiencies than similar devices built with the same materials. The top perovskite cell has a wide bandgap of 1.75 eV and the bottom perovskite cell has a bandgap of 1.25 eV.

Reverse bias – a hidden challenge for perovskite solar cell stability


New research from renowned PV scientist Martin Green and colleagues at UNSW reveals that perovskite solar cells may struggle to deal with reverse-bias caused by uneven shading or other issues likely to appear in the field. Both the reverse-bias itself and resulting build up of heat can cause several of the materials commonly used in perovskite solar cells to degrade, and these issues have received only limited attention in research published to date. Solutions, however, are at hand.

Japan’s first vertical agrivoltaic project


The facility was built with heterojunction modules and mounting systems provided by German companies Luxor Solar and Next2Sun, respectively. The distance between the panel rows ranges from 8 to 10 meters and the agricultural surface within the rows will be utilized by local livestock farmers as pasture.

Ultra-thin perovskite-organic tandem solar cell with 24.0% efficiency


Researchers in Germany have built a perovskite-organic solar cell with low interfacial losses and a high open-circuit voltage. The device achieved an open-circuit voltage of 2.15 V, a short-circuit current of 14.0 mA cm−², and a fill factor of 80%.

Could ‘hot carrier’ solar cells break the theoretical efficiency limit?


Up to 50% of the energy absorbed by a solar cell is lost as heat. Scientists are now developing a third generation of “hot carrier” solar cells that take advantage of this heat, potentially breaking the Shockley-Queisser limit of silicon-based PV.
