Silicon heterojunction (SHJ) solar cells have achieved a record efficiency of 26.81% in a front/back-contacted (FBC) configuration. Moreover, thanks to their advantageous high VOC and good infrared response, SHJ solar cells can be further combined with wide bandgap perovskite cells forming tandem devices to enable efficiencies well above 33%.
The basic structure of HJT solar cell is a heterojunction formed by stacking intrinsic and doped hydrogenated amorphous silicon layers on a crystalline silicon wafer, and the cleanliness of the crystalline silicon surface has a direct impact on the heterojunction and interface.
The application of silicon heterojunction solar cells for ultra-high efficiency perovskite/c-Si and III-V/c-Si tandem devices is also reviewed. In the last, the perspective, challenge and potential solutions of silicon heterojunction solar cells, as well as the tandem solar cells are discussed. 1. Introduction
There are two varieties of c-Si, polycrystalline and monocrystalline silicon, but monocrystalline is the only one considered for HJT solar cells since it has a higher purity and therefore more efficient. Amorphous silicon is used in thin-film PV technology and is the second most important material for manufacturing heterojunction solar cells.
Thus, silicon HJT holds a place of choice in the intense competition occurring nowadays for market supremacy in the photovoltaics world. Books > Photovoltaic Solar Energy: Fr... > Heterojunction Silicon Solar Cells: Rec...
The HJT cell initially investigated by Sanyo, Japan is a single-sided heterojunction structure, where the n-type diffused emitter is replaced by an n-type a-Si:H layer, and also a TCO layer is added compared to a single-crystal pn-junction solar cell.
