A new six-junction solar cell, developed by NREL (National Renewable Energy Laboratory), converts 47.1% of incident light into electricity when combined with optical concentration. Indications thus ...

A perovskite-on-silicon tandem cell has a theoretical efficiency limit of 43% vs 29% for silicon cells. The 2021 commercial product will likely reach 30% energy conversion efficiency. Perovskites can ...

Researchers have fabricated a new four-terminal organic solar cell with a tandem configuration with a 16.94% power conversion efficiency (PCE). The new device is composed by a highly transparent front ...

Traditional silicon solar cells can only absorb the solar spectrum at wavelengths below 1.1 μm. Here we proposed a breakthrough in harvesting solar energy below Si bandgap through conversion of hot ...

Scientists in China have constructed and tested a device that uses redox couples paired with a single triple-junction amorphous-silicon photoelectrode. When tested under a xenon lamp simulating one ...

The new prototype uses a triple-junction compound design, which sandwiches the solar cell between layers of film. The module is expected to be used in a variety of vehicles, an application that ...
