【Cov khoom piav qhia】

Silicon Heterojunction Technology (HJT) yog ua raws li lub emitter thiab sab nraub qaum teb (BSF) uas yog tsim los ntawm qhov kub thiab txias ntawm ultra-nyias txheej ntawm amorphous silicon (a-Si: H) ntawm ob sab ntawm zoo heev ntxuav monocrystalline silicon wafers , tsawg dua 160 μm nyob rau hauv thickness, qhov twg electrons thiab qhov yog photogenerated.
