Among PC technologies, amorphous silicon-based silicon heterojunction (SHJ) solar cells have established the world record power conversion efficiency for single-junction c-Si PV. Due to their excellent performance and simple design, they are also the preferred bottom cell technology for perovskite/silicon tandems.
Silicon heterojunction (SHJ) solar cells, as one of the most promising passivated contact solar cell technologies of the next generation, have the advantages of high conversion efficiency, high open-circuit voltage, low-temperature coefficient, and no potential-induced degradation.
Thin and flexible crystalline silicon (c-Si) heterojunction solar cells are fabricated with very simple processes and demonstrated experimentally based on MoO x /indium tin oxide (ITO) and LiF x /Al as the dopant-free hole- and electron-selective contacts, respectively.
This perspective focuses on the latter PC technology, more commonly known as silicon heterojunction (SHJ) technology, which achieved the highest power conversion efficiency to date for a single-junction c-Si solar cell. Moreover, the SHJ technology has been utilized in realizing world record perovskite/c-Si tandem solar cells.
Recently, the successful development of silicon heterojunction technology has significantly increased the power conversion efficiency (PCE) of crystalline silicon solar cells to 27.30%.
Eventually, we report a series of certified power conversion efficiencies of up to 26.81% and fill factors up to 86.59% on industry-grade silicon wafers (274 cm2, M6 size). Improvements in the power conversion efficiency of silicon heterojunction solar cells would consolidate their potential for commercialization.
