Abstract

Silicon heterojunction solar cells usually employ doped amorphous silicon layers as carrier selective contacts. However, these layers may cause parasitic optical absorption losses and moderate fill factor values due to high contact resistivity with the transparent electrodes. In this study, we show that the replacement of the amorphous doped layers with microcrystalline one is beneficial for both optical and electrical aspects which include a better Jsc when they are applied to the front, lower contact resistivity compared to amorphous layers and better FF thanks to the crystalline phase and the higher doping efficiency. Strikingly, hole collecting microcrystalline layer suppresses the transport barrier effect occurs at valance band offset, allowing a FF in the range of 70% at -100 °C while it is dropping to 40% for standard amorphous doped layers.
