Research on Characteristics of the Photovoltaic Cells Integrated on Chip

Abstract:

The influence factors of Photovoltaic (PV) cells characteristics integrated on chip were analyzed based on the fabrication process and the structure of the PV cells and CMOS devices. The results show the substrate doping concentration, the emitter doping concentration, the emitter junction depth and the thickness of device layer directly determine the conversion efficiency, open voltage and the light-generated current of photovoltaic cells. In the emitter doping concentration range of 1×10¹⁹/cm³ to 1×10²¹/cm³ and the substrate doping concentration range of 1.0×10¹⁵/cm³ to 1.0×10¹⁷/cm³, the Photovoltaic cells have batter conversion characteristics. The PV cells were designed based on the analysis results in PC1D, and the conversion efficiency is 9.43%. The Photovoltaic cells and the CMOS devices have batter fabrication technology compatibility integrated on chip.
