Ka'idar canza makamashin hasken rana zuwa ma'auni daban-daban ita ce: makamashin haske yana motsa electrons don samar da makamashin lantarki;motsi na electrons yana samar da wutar lantarki, ta haka ne ke canza makamashin haske zuwa makamashin lantarki.
Tsarin canza makamashin hasken rana zuwa makamashin lantarki ana kiransa samar da wutar lantarki ta photovoltaic.Ka'idar samar da wutar lantarki ta photovoltaic ita ce amfani da photons a cikin hasken rana don tada hankalin electrons a cikin sel na photovoltaic don samar da halin yanzu.Tantanin halitta na hotovoltaic na'ura ce ta semiconductor yawanci tana kunshe da wafern silicon da yawa.
Wafer siliki ya ƙunshi abubuwa biyu, silicon-doped silicon da boron-doped silicon, waɗanda ke da tsarin lantarki daban-daban.Lokacin da hasken rana ya buga wafer silicon, photons suna buga electrons a cikin wafer siliki, suna burge su daga atom ɗin su kuma suna samar da nau'i-nau'i na electron-rami a cikin wafer.Silicon doped tare da phosphorus semiconductor ne nau'in n-nau'i, kuma siliki da aka yi da boron shine nau'in p-type semiconductor.Lokacin da aka haɗa su biyu, ana samun filin lantarki, kuma filin lantarki yana sa electrons su motsa su samar da wutar lantarki.
