5. Summary Silicon heterojunction (SHJ) solar cells are part of the family of solar cells with passivating contacts; they feature high open-circuit voltages (V OC), generally well above 700 mV. Achieving of fill-factors (FF) comparable to the best high-efficiency devices based on homo-junctions has long been a challenge for SHJ solar cells.
Due to stable and high power conversion efficiency (PCE), it is expected that silicon heterojunction (SHJ) solar cells will dominate the photovoltaic market. So far, the highest PCE of the SHJ-interdigitated back contact (IBC) solar cells has reached 26.7%, approximately approaching the theoretical Shockley–Queisser (SQ) limitation of 29.4%.
Recently, the successful development of silicon heterojunction technology has significantly increased the power conversion efficiency (PCE) of crystalline silicon solar cells to 27.30%.
On the back side, an electron collecting stack is used, and it is composed of an intrinsic a-Si:H passivation layer, a doped n-type amorphous silicon (both deposited by PECVD), a TCO layer and a metallic contacting layer (deposited by PVD).

In recent years a wide variety of novel materials have been investigated as carrier-selective contacts for silicon heterojunction solar cells.
Recently, a new efficiency world record for silicon solar cells of 26.7% has been set by Kaneka Corp. using this technology. This was mainly achieved by remarkably increasing the fill-factor (FF) to 84.9% - the highest FF published for a silicon solar cell to date. High FF have for long been a challenge for SHJ technology.
