Amaseli e-photovoltaic asetshenziswa kakhulu emkhathini, kwezempi nakwezinye izindawo ekuqaleni kwe-photon – Eminyakeni engama-20 edlule, izindleko zamaseli e-photovoltaic zehle kakhulu ukukhuthaza i-photovoltaic ye-space cave jump ezinhlobonhlobo zezicelo zomhlaba wonke. Ekupheleni kuka-2019, umthamo ophelele ofakiwe we-solar PV emhlabeni wonke ufinyelele ku-616GW, futhi kulindeleke ukuthi ufinyelele ku-50% womthamo wokukhiqiza amandla emhlabeni wonke ngo-2050. Ngenxa yezinto ze-semiconductor ze-photovoltaic ekumuncweni kokukhanya kwenzeka kakhulu kuma-micron ambalwa kuya kwamakhulu ama-micron ububanzi bobukhulu kanye nobuso bezinto ze-semiconductor bokusebenza kweseli kubaluleke kakhulu, ukuze ubuchwepheshe befilimu encane ye-vacuum bube nobubanzi obukhulu bezicelo ekukhiqizeni ugesi welanga.
Amaseli e-photovoltaic asezimbonini ahlukaniswe ngezigaba ezimbili eziyinhloko: amaseli elanga e-silicon acwebezelayo kanye namaseli elanga e-thin film. Ubuchwepheshe besimanje be-crystalline silicon cell buhlanganisa ubuchwepheshe be-emitter engasebenzi kanye ne-backside cell (PERC), ubuchwepheshe be-heterojunction (HJT), ubuchwepheshe be-backside full diffusion (PERT) obungasebenzi, kanye nobuchwepheshe be-tunneled oxide passivated contact (Topcon) cell. Imisebenzi yamafilimu amancane kumaseli e-crystalline silicon ihlanganisa kakhulu i-passivation, reflection reflection, P/N doping, kanye ne-conductivity. Ubuchwepheshe bebhethri le-thin-film obujwayelekile buhlanganisa i-cadmium telluride, i-copper indium gallium selenide, kanye ne-chalcogenide. Amafilimu amancane asetshenziswa kakhulu njengengqimba emunca ukukhanya, ungqimba oluqhubayo, njll. kuwo. Ukulungiswa kwamafilimu amancane kumaseli e-photovoltaic kuvame ukusetshenziswa ezinhlotsheni ezahlukene zobuchwepheshe bokumboza i-vacuum.
