An fi amfani da ƙwayoyin photovoltaic a sararin samaniya, sojoji da sauran fannoni a farkon photon - A cikin shekaru 20 da suka gabata, farashin ƙwayoyin photovoltaic ya faɗi sosai don haɓaka tsalle-tsalle na kogon sararin samaniya a cikin aikace-aikacen duniya daban-daban. A ƙarshen 2019, jimlar ƙarfin PV na hasken rana da aka shigar a duk duniya ya kai 616GW, kuma ana sa ran zai kai kashi 50% na jimlar ƙarfin samar da wutar lantarki a duniya nan da 2050. Saboda kayan semiconductor na photovoltaic, shaye-shayen haske galibi yana faruwa ne a cikin kauri kaɗan zuwa ɗaruruwan microns kuma saman kayan semiconductor na aikin ƙwayar halitta yana da matukar muhimmanci, don haka fasahar fim ɗin da ba ta da ma'ana tana da aikace-aikace iri-iri a cikin kera wutar lantarki ta hasken rana.
Kwayoyin hasken rana na masana'antu sun kasu kashi biyu: ƙwayoyin hasken rana na silicon mai siffar crystalline da ƙwayoyin hasken rana na fim mai siffar thinner. Fasaha ta zamani ta silicon mai siffar crystalline sun haɗa da fasahar passivated emitter da fasahar bayan cell (PERC), fasahar heterojunction (HJT), fasahar passivated emitter mai siffar thinner full diffusion (PERT), da fasahar passivated oxide mai siffar passivated contact (Topcon). Ayyukan fina-finai masu siffar thinner a cikin ƙwayoyin silicon mai siffar crystalline sun haɗa da passivation, rage haske, P/N doping, da kuma conductivity. Fasaha ta batirin bakin ciki na yau da kullun sun haɗa da cadmium telluride, jan ƙarfe indium gallium selenide, da chalcogenide. Fina-finan bakin ciki galibi ana amfani da su azaman Layer mai ɗaukar haske, Layer mai ɗaukar haske, da sauransu a cikinsu. Shirye-shiryen fina-finai masu siffar thinner a cikin ƙwayoyin photovoltaic ana amfani da su sau da yawa a cikin nau'ikan fasahar rufewa ta injina daban-daban.
