Iiseli ze-Photovoltaic zazisetyenziswa kakhulu esibhakabhakeni, emkhosini nakwezinye iindawo kwi-photon yokuqala – Kwiminyaka engama-20 edlulileyo, iindleko zeeseli ze-photovoltaic zehle kakhulu ukukhuthaza i-photovoltaic yokungena kwi-space cave jump kwiindidi ezahlukeneyo zezicelo zehlabathi. Ekupheleni kuka-2019, umthamo opheleleyo we-PV yelanga efakiweyo kwihlabathi liphela ufikelele kwi-616GW, kwaye kulindeleke ukuba ifikelele kwi-50% yamandla okuvelisa amandla ehlabathi ngo-2050. Ngenxa yezinto ze-semiconductor ze-photovoltaic ekufakweni kokukhanya kwenzeka ikakhulu kwii-microns ezimbalwa ukuya kumakhulu ee-microns ububanzi bobukhulu kunye nokusebenza kwezixhobo ze-semiconductor kumphezulu weseli kubaluleke kakhulu, ukuze iteknoloji yefilimu encinci ye-vacuum ibe noluhlu olubanzi lwezicelo ekuvelisweni kombane welanga.
Iiseli ze-photovoltaic ezikwimizi-mveliso zahlulwe kwiindidi ezimbini eziphambili: iiseli zelanga ze-silicon ezikristali kunye neeseli zelanga ezibhityileyo. Iiteknoloji zeseli ze-silicon ezikristali zanamhlanje ziquka iteknoloji ye-emitter engasebenziyo kunye ne-backside cell (PERC), iteknoloji ye-heterojunction (HJT), iteknoloji ye-emitter engasebenziyo backside full diffusion (PERT), kunye neteknoloji yeseli ye-tunneled oxide engasebenziyo (Topcon). Imisebenzi yeefilimu ezibhityileyo kwiiseli ze-silicon ezikristali ibandakanya kakhulu i-passivation, i-reflection reduction, i-P/N doping, kunye ne-conductivity. Iiteknoloji zebhetri ze-thin-film eziphambili ziquka i-cadmium telluride, i-copper indium gallium selenide, kunye ne-chalcogenide. Iifilimu ezibhityileyo zisetyenziswa kakhulu njengomaleko ofunxa ukukhanya, umaleko oqhubayo, njl.njl. kuzo. Ukulungiswa kweefilimu ezibhityileyo kwiiseli ze-photovoltaic kusetyenziswa rhoqo kwiintlobo ezahlukeneyo zobuchwepheshe bokugquma nge-vacuum.
