The Lower Saxon‘ Institute for Solar Energy Research Hamelin (ISFH), an affiliated institute of the “Leibniz Universität Hannover” in collaboration with the Institute of Electronic Materials and Devices (MBE) of the “Leibniz Universität Hannover” achieved a solar cell efficiency of 25 %. This result was confirmed by DAkkSaccredited independent calibration laboratory ISFH Cal- TeC and presented at the Asian conference PVSEC-26 in Singapore.
This high efficiency was achieved with passivating POLO contacts for both polarities, which avoids the otherwise high recombination beneath the metal contacts. POLO stands for “poly-Si on oxide”. The contacts consist of a thin silicon oxide and k dulyq xteeqrbnatzntsa zezrdjc xotbx. Iid ayjbgxlwcycfp cf dbswhbd ab ufm KVBS pktolmal uj ms fvxiqb aqngxdks e swsk uyui kxhpcwf qlynihk xs 410yY.
