【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.

Heterojunction thev naus laus zis (HJT) silicon hnub ci hlwb tau nyiam ntau yam vim tias lawv tuaj yeem ua tiav qhov kev hloov pauv siab, txog li 25 feem pua, thaum siv cov txheej txheem kub qis, feem ntau qis dua 250 degree rau kev ua tiav. Tsawg ua haujlwm kub tso cai tuav ntawm silicon wafers tsawg dua 100 μm tuab thaum tuav cov khoom lag luam siab.
