Unugyada sawir-qaadista ayaa inta badan loo adeegsaday meel bannaan, militari iyo goobo kale oo hore oo sawir-qaadis ah - 20-kii sano ee la soo dhaafay, qiimaha unugyada sawir-qaadista ayaa si aad ah hoos ugu dhacay si kor loogu qaado godka bannaan ee boodhka sawir-qaadista ee ballaaran ee codsiyada caalamiga ah. Dhamaadka 2019, wadarta awoodda rakibay ee PV qorraxda adduunka oo dhan waxay gaartay 616GW, waxaana la filayaa in ay gaarto 50% awoodda koronta guud ee adduunka marka la gaaro 2050. Sababtoo ah walxaha semiconductor ee sawir-qaadista ee nuugista iftiinka ayaa inta badan ku dhaca dhowr microns ilaa boqolaal microns dhumucdiisuna waxay u badan tahay, waxqabadka unugga khafiifka ah wuxuu leeyahay dusha sare ee dhumucdiisuna tahay iyo waxqabadka semiconductor-ka. codsiyada kala duwan ee soo saaridda korontada cadceedda.
Unugyada sawir-qaadista ee warshadaysan waxay u kala baxaan laba qaybood oo waaweyn: unugyo cadceedda silikoon crystalline iyo unugyo cadceed oo filim khafiif ah. Farshaxanka casriga ah ee tignoolajiyada unugyada silikoonka waxaa ka mid ah emitter passivated iyo backside cell (PERC), tignoolajiyada heterojunction (HJT), tignoolajiyada hawada sare ee dib-u-baxa dib u faafinta buuxda (PERT), iyo tunneled oxide passivated contact (Topcon) tignoolajiyada unugyada. Shaqooyinka filimada khafiifka ah ee unugyada silikon crystalline inta badan waxaa ka mid ah dareen-celinta, dhimista milicsiga, P/N doping, iyo conductivity. Tignoolajiyada caadiga ah ee batteriga khafiifka ah waxaa ka mid ah cadmium telluride, copper indium gallium selenide, iyo chalcogenide. Aflaanta khafiifka ah waxaa inta badan loo isticmaalaa sida lakab nuugaya iftiinka, lakabka dhaqdhaqaajinta, iwm. Diyaarinta filimada khafiifka ah ee unugyada photovoltaic waxaa inta badan loo isticmaalaa noocyada kala duwan ee tiknoolajiyada daahan vacuum.
