Cov hlwb photovoltaic feem ntau yog siv rau hauv qhov chaw, tub rog thiab lwm qhov chaw thaum ntxov photon - Hauv 20 xyoo dhau los, tus nqi ntawm cov hlwb photovoltaic tau poob qis heev los txhawb qhov chaw qhov tsua dhia photovoltaic hauv ntau yam kev siv thoob ntiaj teb. Thaum kawg ntawm xyoo 2019, tag nrho cov peev xwm ntsia ntawm lub hnub ci PV thoob ntiaj teb tau mus txog 616GW, thiab xav tias yuav ncav cuag 50% ntawm lub ntiaj teb tag nrho lub peev xwm tsim hluav taws xob los ntawm xyoo 2050. Vim yog cov khoom siv photovoltaic semiconductor ntawm kev nqus ntawm lub teeb feem ntau tshwm sim hauv ob peb microns mus rau ntau pua microns thickness ntau thiab semiconductor khoom nto ntawm lub cell kev ua tau zoo yog qhov tseem ceeb heev, yog li ntawd cov thev naus laus zis nqus tsev nyias nyias muaj ntau yam kev siv hauv kev tsim hluav taws xob hnub ci.
Cov cell photovoltaic uas muaj kev lag luam muaj ob pawg tseem ceeb: crystalline silicon solar cells thiab thin film solar cells. Cov thev naus laus zis crystalline silicon cell niaj hnub no suav nrog passivated emitter thiab backside cell (PERC) technology, heterojunction (HJT) technology, passivated emitter backside full diffusion (PERT) technology, thiab tunneled oxide passivated contact (Topcon) cell technology. Cov haujlwm ntawm cov zaj duab xis nyias hauv cov cell crystalline silicon feem ntau suav nrog passivation, reflection reduction, P/N doping, thiab conductivity. Cov thev naus laus zis roj teeb nyias feem ntau suav nrog cadmium telluride, copper indium gallium selenide, thiab chalcogenide. Cov zaj duab xis nyias feem ntau yog siv ua txheej nqus lub teeb, txheej conductive, thiab lwm yam hauv lawv. Kev npaj cov zaj duab xis nyias hauv cov cell photovoltaic feem ntau siv rau ntau hom txheej txheej nqus tsev.
