Lub thickness ntawm monocrystalline silicon wafer yog dab tsi?

Nrog rau kev nce qib ntawm kev lag luam saw kev koom tes, cov txheej txheem thinning yog nrawm. Lub thickness ntawm silicon wafers muaj feem xyuam rau lub automation, yield, thiab conversion efficiency ntawm hlwb, thiab yuav tsum tau kom phim cov kev xav tau ntawm downstream cell thiab module manufacturers. Yog li ntawd, thinning yog ntau nyob ntawm kev koom tes thiab kev nce qib ntawm txhua qhov kev sib txuas hauv cov saw hlau.
Xyoo 2020, qhov nruab nrab tuab ntawm polycrystalline silicon wafers yog 180 μm, qhov nruab nrab tuab ntawm P-hom monocrystalline silicon wafers yog li 175 μm, qhov nruab nrab tuab ntawm N-hom silicon wafers yog 168 μm, qhov nruab nrab tuab ntawm N-hom silicon wafers rau TOPCon hlwb yog 175 μm, thiab qhov nruab nrab thickness ntawm silicon wafers rau heterojunction hlwb txog 150 μm.
1. P-hom monocrystalline silicon wafers: Nyias hlais tau ntsib ntau qhov chaw xws li 350 μm, 250 μm, 220 μm, 200 μm, thiab 180 μm, thiab xav tias yuav ncav cuag 170 μm hauv 2021. Cov txheej txheem nyias nyias ntawm {{ 9}} μm tau loj hlob thiab xav tias yuav ncav cuag 160 μm hauv 2025 .
2. N-hom monocrystalline silicon wafers: Piv nrog P-hom silicon wafers, N-hom silicon wafers yooj yim dua ua kom nyias. Nws cia siab tias yuav ncav cuag 160-165 μm hauv 2021. Tam sim no, 120-140 μm wafer tshuab muaj, thiab nws xav tias yuav ncav cuag 100-120 μm nyob rau hauv ntev.
3. N-hom monocrystalline silicon wafers rau cov hlwb heterojunction: HJT yog cov qauv ntawm tes zoo tshaj plaws thiab cov txheej txheem rau thinning, thiab muaj txiaj ntsig zoo hauv kev thinning. Cov laj thawj yog:
(1) Symmetrical qauv, tsis tshua muaj kub los yog tsis muaj kev ntxhov siab txheej txheem tuaj yeem hloov mus rau thinner silicon wafers.
(2) Kev hloov dua siab tshiab tsis cuam tshuam los ntawm qhov tuab. Txawm hais tias lub thickness yog txo kom txog li 100 μm, nyob ntawm lub ultra-low nto recombination, qhov poob ntawm lub luv luv-circuit tam sim no Isc yuav tau them los ntawm qhov qhib-circuit voltage Voc.
Raws li cov kev kwv yees muaj feem xyuam, lub thickness ntawm heterojunction N-hom silicon wafers yuav ncav cuag 140, 130, thiab 120 μm hauv 2024, 2027, thiab 2030, raws li, thiab theoretical txwv ntawm thinning tuaj yeem ncav cuag qis dua 100 μm.
