Perovskite solar cells, often called PeSCs, are changing the way energy is captured—especially indoors. Unlike the rigid and ...

Where an ideal single-junction cell has a maximum efficiency of 33.16% in theory, a tandem or multi-junction solar cell with “infinite” junctions could hit an efficiency of up to 86.8%.

Perovskites have emerged as an exciting material when it comes to next-generation solar cells, but they aren’t without their problems. While they promise great leaps in efficiency, keeping all ...

In solar cells and light-emitting diodes, maintaining the excited state kinetics of molecules against annihilation is a race against time. These systems need to strike a careful balance between ...

Solar cells are constantly improving on the road to maximum efficiency. Now, three records have been broken by two different devices, including one that pushes the highest overall solar conversion ...

The tandem solar cell uses a pair of semiconductors able to capture different parts of the light spectrum. Silicon captures infrared light, while perovskite captures visible light.

Scientists have set a new efficiency record for perovskite-silicon solar cells. They've almost reached a critical "proof of concept" milestone of 30 percent, clocking 29.15 percent in this experiment.

Mapping the energy level alignment at donor/acceptor interfaces in non-fullerene organic solar cells. Nature Communications, 2022; 13 (1) DOI: 10.1038/s41467-022-29702-w ...

Doping refers to the distortion of a crystal structure by introducing an impurity. In the case of polycrystalline solar cells, this can be done by melting together crystals called CZTSSe with ...

The new results published in Science by the NREL research team is the first report of MEG manifested as an external photocurrent quantum yield greater than 100 percent measured in operating quantum ...

Nevertheless, light trapping surfaces look a promising way to increase the efficiency of thin film solar cells–provided somebody can work out how to make them cheaply enough.

Efficient solar cells are close to a reality, having reached 40 percent efficiency or better. Unfortunately, there is a small fly in the ointment: the cells are really expensive to make, and ...
