Abstract

This work presents results of a laboratory-scale interdigitated back contact (IBC) solar cell with an independently measured efficiency of 25.0%, featuring open-circuit voltage of 716 mV, short-circuit current of 43.0 mA.cm(-2)and fill factor of 81.0%. Notably, the high efficiency was achieved based on significant improvements resulting from the optimised cell structure, excellent SiO2-SiNx-SiOx(ONO) surface passivation, detailed bulk lifetime management strategy and improved random pyramid texturing. Experimental details and analysis of the individual improvements over prior work are presented in-depth.
