Lisele tsa photovoltaic li ne li sebelisoa haholo-holo sebakeng, sesoleng le masimong a mang qalong ea photon - Lilemong tse 20 tse fetileng, litšenyehelo tsa lisele tsa photovoltaic li theohile haholo ho khothaletsa photovoltaic ea lehaha la sebaka lits'ebetsong tse fapaneng tsa lefats'e. Qetellong ea 2019, bokhoni bohle ba PV ea letsatsi bo kentsoeng lefatšeng ka bophara bo fihlile ho 616GW, 'me ho lebelletsoe hore bo fihle ho 50% ea bokhoni bohle ba tlhahiso ea matla lefatšeng ka bophara ka 2050. Ka lebaka la thepa ea semiconductor ea photovoltaic holim'a monya oa leseli haholo-holo e etsahala ka har'a li-microns tse 'maloa ho isa ho makholo a li-microns botenya le bokaholimo ba thepa ea semiconductor ea ts'ebetso ea sele bo bohlokoa haholo, e le hore theknoloji ea filimi e tšesaane ea vacuum e na le mefuta e mengata ea lits'ebetso tlhahisong ea motlakase oa letsatsi.
Lisele tsa photovoltaic tse tsoetseng pele li oela likarolong tse peli tse ka sehloohong: lisele tsa letsatsi tsa silicon tse kristale le lisele tsa letsatsi tse tšesaane. Litheknoloji tsa sejoale-joale tsa sele ea silicon tse kristale li kenyelletsa theknoloji ea emitter e sa sebetseng le ea cellside (PERC), theknoloji ea heterojunction (HJT), theknoloji ea backside full diffusion (PERT) e sa sebetseng, le theknoloji ea sele ea tunneled oxide e sa sebetseng (Topcon). Mesebetsi ea lifilimi tse tšesaane liseleng tsa silicon tse kristale e kenyelletsa haholo-holo ho se sebetse, ho fokotsa ho bonahatsa, ho sebelisa P/N doping, le ho tsamaisa motlakase. Litheknoloji tse kholo tsa betri ea thin-film li kenyelletsa cadmium telluride, copper indium gallium selenide, le chalcogenide. Lifilimi tse tšesaane li sebelisoa haholo e le lera le monyang leseli, lera le tsamaisang motlakase, jj. ho tsona. Ho lokisoa ha lifilimi tse tšesaane liseleng tsa photovoltaic ho sebelisoa hangata mefuteng e fapaneng ea theknoloji ea ho roala ka vacuum.
