摘要
Abstract
Currently,tunnel oxide passivated contact structures has become a hot technology in the re-search and was applied to N-type high-efficiency solar cells.For TOPCon solar cells,the surface mor-phology on the back becomes one of the key factors affecting the tunnel passivated contact perfor-mance.This research based on TOPCon solar cell substrate used KOH alkaline solution process to prepare different morphology structures on the back surface of silicon wafer,and then tested perfor-mances of different structures and even finished solar cells samples.During this research,the influ-ences of different surface texture morphologies with solar cells bas been specifically studied by testing the micro morphology,light reflectivity,and passivation performance.As shown in the experiment re-sults,the optimal texture morphology structure preparation parameters and process conditions were identified to improve solar cells performance.关键词
