Amaseli e-Photovoltaic ayesetshenziswa ngokuyinhloko emkhathini, ezempi nakweminye imikhakha ekuqaleni kwe-photon - Eminyakeni engu-20 edlule, izindleko zamaseli e-photovoltaic ziye zehla ngokuphawulekayo ukuze kuthuthukiswe umhume wesikhala gxuma i-photovoltaic ezinhlobonhlobo zezinhlelo zokusebenza zomhlaba jikelele. Ekupheleni kuka-2019, isamba esifakiwe somthamo we-solar PV emhlabeni wonke sifinyelele ku-616GW, futhi kulindeleke ukuthi sifinyelele ku-50% wengqikithi yamandla okukhiqiza amandla ngo-2050. Ngenxa ye-photovoltaic semiconductor material ekumuncwani kokukhanya ikakhulukazi kwenzeka kuma-microns ambalwa kuya kumakhulu ama-microns ama-microns ugqinsi olubalulekile futhi i-semicondu yefilimu yobuchwepheshe ibaluleke kakhulu. inezinhlobonhlobo zezicelo ekwenziweni kukagesi welanga.
Amaseli e-photovoltaic athuthukisiwe awela ezigabeni ezimbili eziyinhloko: amaseli elanga e-crystalline silicon kanye namaseli amancane elanga efilimu. Ubuchwepheshe besimanjemanje be-crystalline crystalline silicon cell buhlanganisa ubuchwepheshe be-passivated emitter kanye ne-backside cell (PERC), ubuchwepheshe be-heterojunction (HJT), ubuchwepheshe be-passivated emitter backside full diffusion (PERT), kanye nobuchwepheshe beseli ye-tunneled oxide passivated (Topcon). Imisebenzi yamafilimu amancanyana kumaseli e-silicon e-crystalline ikakhulukazi ihlanganisa ukudlula, ukunciphisa ukubonakaliswa, i-P/N doping, kanye ne-conductivity. Ubuchwepheshe bebhethri lefilimu elincanyana elivamile buhlanganisa i-cadmium telluride, i-copper indium gallium selenide, ne-chalcogenide. Amafilimu azacile asetshenziswa kakhulu njengongqimba olumunca ukukhanya, ungqimba olubambayo, njll. kuwo. Ukulungiswa kwamafilimu amancanyana kumaseli e-photovoltaic kuvame ukusetshenziswa ezinhlotsheni ezahlukahlukene zobuchwepheshe be-vacuum coating.
