Emmerthal/Hannover: The Institute for Solar Energy Research Hamelin (ISFH) and the Leibniz Universität Hannover demonstrated the fabrication of a crystalline silicon solar cell on p-type wafer material with an independently confirmed energy conversion efficiency of (26.10 ± 0.31) % under one sun. This is a world record for p-type Si material as well as a European record for crystalline Si.
