An yi amfani da sel na hotuna da yawa a cikin sararin samaniya, soja da sauran wurare a farkon photon - A cikin shekaru 20 da suka gabata, farashin sel na hoto ya ragu sosai don inganta kogon sararin samaniya mai tsalle photovoltaic a cikin aikace-aikacen duniya da yawa. A karshen 2019, jimlar shigar ikon hasken rana PV a duk duniya ya kai 616GW, kuma ana sa ran ya kai 50% na duniya jimlar ikon samar da wutar lantarki ta 2050. Saboda photovoltaic semiconductor abu a kan sha na haske yafi faruwa a cikin 'yan microns zuwa daruruwan microns kauri kewayon, da bakin ciki fasahar da wani bakin ciki fasahar da wani abu mai muhimmanci surface da semiconductor. aikace-aikace da yawa a cikin kera wutar lantarki ta hasken rana.
Kwayoyin photovoltaic da aka samar da masana'antu sun fada cikin manyan nau'i biyu: sel siliki na hasken rana da sel na fim na bakin ciki. Fasahar siliki ta zamani ta zamani ta haɗa da fasahar emitter da baya (PERC), fasahar heterojunction (HJT), fasaha mai wuce gona da iri na baya-baya (PERT) fasaha, da kuma fasahar tantanin halitta mai ratsawa ta oxide (Topcon).
