A novel system of optical elements redirects light so that the irradiance on the cells is increased, no light passes the pv module “unused” and more power is generated.
When one thinks of photovoltaic cells, then it is usually in connection with the conversion of solar radiation into electricity, a main research area at Fraunhofer ISE in line with the energy transformation. However...
If you want to know the efficiency of a solar cell exactly, it is likely that you will land in Freiburg, Germany sooner or later. For 30 years high-precision reference solar cells – and for almost 25 years reference...
