Abstract:A p‐type crystalline silicon (c‐Si) passivated emitter and rear contact (PERC) nowadays have become mainstream in the highly competitive photovoltaic market. Herein, the recently popular passivating contact concept on the front textured surface of p‐type c‐Si PERC solar cells is applied. The full‐area textured passivating contact consists of an ultrathin SiO2 film of ≈1.5 nm thickness grown with thermal oxidation and phosphorus‐doped polysilicon (poly‐Si) contact layer by low‐pressure chemical vapor deposition… Show more
“…To solve this problem, Ding et al used LPCVD equipment to prepare a TOPCon structure. 187 By fully optimizing the thickness of poly-Si, the drive-in temperature and time of phosphorus atoms, and the crystallinity of poly-Si before and after annealing, it was found that a TOPCon structure under suitable conditions can not only improve the collection efficiency of carriers by metal electrodes, but it can also maintain superior interface passivation characteristics.…”

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
