Carrier-selective contact technology plays a critical role in achieving high-performance photovoltaic devices, but intrinsic limitations within this widely used technology limit further advances in efficiency. Using a combination of experimental characterization, theoretical modeling, and variable temperature experiments, the authors investigate carrier transport mechanisms in silicon heterojunction solar cells and determine that thermal emission dominates the carrier transport process in TiN/n-Si heterojunction.
