Cov cell photovoltaic tau siv tsuas yog hauv qhov chaw, tub rog thiab lwm thaj chaw hauv photon thaum ntxov - Hauv 20 xyoo dhau los, tus nqi ntawm cov cell photovoltaic tau poob qis heev los txhawb qhov chaw qhov tsua dhia photovoltaic hauv ntau yam kev siv thoob ntiaj teb. Thaum kawg ntawm 2019, tag nrho lub peev xwm ntawm lub hnub ci PV thoob ntiaj teb tau mus txog 616GW, thiab xav tias yuav ncav cuag 50% ntawm lub ntiaj teb lub zog tsim hluav taws xob los ntawm 2050. Vim tias cov khoom siv hluav taws xob photovoltaic semiconductor ntawm kev nqus ntawm lub teeb feem ntau tshwm sim hauv ob peb microns mus rau ntau pua microns thickness ntau thiab cov khoom siv hluav taws xob semiconductor yog qhov tseem ceeb heev. ntau yam kev siv hauv kev tsim hluav taws xob hnub ci.
Industrialized photovoltaic cells poob rau hauv ob pawg tseem ceeb: crystalline silicon solar cells thiab nyias zaj duab xis hnub ci. Lub xeev-of-the-art crystalline silicon cell technologies suav nrog passivated emitter thiab backside cell (PERC) technology, heterojunction (HJT) technology, passivated emitter backside full diffusion (PERT) technology, thiab tunneled oxide passivated hu (Topcon) cell technology. Kev ua haujlwm ntawm cov yeeb yaj kiab nyias hauv crystalline silicon hlwb feem ntau suav nrog passivation, kev xav txo qis, P / N doping, thiab conductivity. Mainstream nyias-film roj teeb technologies muaj xws li cadmium telluride, tooj liab indium gallium selenide, thiab chalcogenide. Nyias zaj duab xis yog tsuas yog siv raws li lub teeb absorbing txheej, conductive txheej, thiab lwm yam nyob rau hauv lawv. Kev npaj ntawm nyias zaj duab xis nyob rau hauv photovoltaic hlwb feem ntau yog siv nyob rau hauv ntau yam ntawm lub tshuab nqus tsev txheej tshuab.
