Abstract: Si heterojunction solar cells based on organic and transition metal oxide selective carrier contact layer are developed to bypass the high-temperature process required for the conventional Si solar cell. We investigated the behavior of n-Si/PEDOT:PSS inorganic-organic heterojunction which revealed a p-n junction characteristic in contradiction with Schottky junction model. Afterward, we developed a simulation model to optimize n-Si/PEDOT:PSS heterojunction solar cells. We propose the use of simple front junction PEDOT:PSS (30 nm) / Si3N4 (40 nm) layer that can achieve efficiency of 18.4% and more complicated interdigitated back contact design that can achieve 20.4%. We fabricate Si/molybdenum oxide heterojunction solar cell structure which can yield high short circuit current density of 34.3 mA/cm2 although the efficiency is limited to 11.6%. Moreover, we propose and analyze the potential of PV-Tower solar cell concept which can generate high power improvement factor over a small footprint.
