Enwetala arụmọrụ cell heterojunction nke 26.6% na ụdị silicon wafers ụdị P.

The heterojunction kpụrụ na amorphous / crystalline silicon interface (a-Si: H / c-Si) interface nwere pụrụ iche electronic Njirimara, adabara silicon heterojunction (SHJ) anyanwụ cell. Mwekota nke ultra-thin a-Si:H passivation oyi akwa nwetara voltaji mepere emepe dị elu (Voc) nke 750 mV. Ọzọkwa, oyi akwa kọntaktị a-Si:H, nke nwere ụdị n-ụdị ma ọ bụ p-ụdị, nwere ike ịgbanye n'ime usoro agwakọtara, na-ebelata nnabata parasitic na ịkwalite nhọrọ nke onye na-ebu na mkpokọta.

LONGi Green Energy Technology Co., Ltd Xu Xixiang, Li Zhenguo, na ndị ọzọ enwetala 26.6% arụmọrụ SHJ anyanwụ cell na ụdị silicon wafers. Ndị ode akwụkwọ jiri usoro mgbasa ozi nke phosphorus na-enweta pretreatment atụmatụ wee jiri nanocrystalline silicon (nc-Si: H) maka kọntaktị ndị na-ebu ibu, na-abawanye arụmọrụ P-ụdị SHJ anyanwụ cell ruo 26.56%, si otú ahụ guzobe akara ngosi arụmọrụ ọhụrụ maka P. -ụdị silicon anyanwụ cell.

Ndị ode akwụkwọ na-enye mkparịta ụka zuru ezu na mmepe usoro ngwaọrụ na nkwalite arụmọrụ fotovoltaic. N'ikpeazụ, a na-eme nyocha nyocha nke ike iji chọpụta ụzọ mmepe nke P-ụdị SHJ teknụzụ anyanwụ.
