Abstract:
Photovoltaics decisively contributes to sustainable energy supply. The efficiency of solar cells in directly converting light energy into electrical energy depends on the material used. Metal-halide perovskites are considered very promising materials for solar cells of the next generation. With these semiconductors named after their special crystal structure, a considerable increase in efficiency was achieved in the past years. Meanwhile, perovskite solar cells have reached an efficiency of up to 25.5 percent, which is quite close to that of silicon solar cells that are presently dominating t ....

Metal-halide perovskites are considered very promising materials for solar cells of the next generation. With these semiconductors named after their special crystal structure, a considerable increase in efficiency was achieved in the past years. Meanwhile, perovskite solar cells have reached an efficiency of up to 25.5 percent, which is quite close to that of silicon solar cells that are presently dominating the market. Moreover, the materials needed for perovskite solar cells are rather abundant. The solar cells can be produced easily and at low cost and they can be used fo ....

Perovskite semiconductors are considered promising materials for solar cells of the next generation. Suitability of a semiconductor for photovoltaics is reflected among others by the so-called photoluminescence quantum efficiency. Researchers of Karlsruhe Institute of Technology (KIT) have now developed a model, by means of which photoluminescence quantum efficiency of perovskite films can be determined exactly for the first time. This is reported in Matter (DOI: 10.1016/j.matt.2021.01.019). ....
