This paper presents a systematic comparison and analysis of two hole transport layers (PEDOT:PSS and MoOX), as well as the heterojunction TOPCon silicon solar cells prepared using these two hole transport layers.Firstly, the photoelectric characteristics of PEDOT:PSS and MoOX films were compared, including work function, resistivity, light absorption, and anti-reflection effects on silicon wafers. Subsequently, based on the film properties, full-back electrode PEDOT:PSS/n-Si and MoOX/n-Si heterojunction solar cells were designed for comparison and investigation. Finally, the performance of the two types of heterojunction solar cells was compared using quantum efficiency tests as well as illumination and darThis paper presents a systematic comparison and analysis of two hole transport layers (PEDOT:PSS and MoOX), as well as the heterojunction silicon solar cells prepared using these two hole transport layers.Firstly, the photoelectric characteristics of PEDOT:PSS and MoOX films were compared, including work function, resistivity, light absorption, and anti-reflection effects on silicon wafers.

Finally, the performance of the two types of heterojunction solar cells was compared using quantum efficiency tests as well as illumination and dark J-V tests. Additionally, a stability test was conducted. The results indicate that PEDOT:PSS/n-Si solar cells exhibit higher PN junction quality and conversion efficiency while MoOX/Si solar cells demonstrate higher open circuit voltage and stability. Through the analysis and comparison of the two types of solar cells, it is conducive to improving and optimizing them more pertinently.k J-V tests. Additionally, a stability test was conducted.
