Gabatarwa ga fasahar fim ɗin hasken rana ta photovoltaic

Bayan gano tasirin hasken rana a Turai a shekarar 1863, Amurka ta samar da tantanin halitta na farko mai amfani da hasken rana (Se) a shekarar 1883. A farkon zamanin, ana amfani da tantanin halitta mai amfani da hasken rana a fannin sararin samaniya, soja da sauran fannoni. A cikin shekaru 20 da suka gabata, raguwar farashin hasken rana ya haifar da yaduwar amfani da hasken rana mai amfani da hasken rana a duk fadin duniya. A karshen shekarar 2019, jimillar karfin hasken rana mai amfani da hasken rana ya kai 616GW a duk duniya, kuma ana sa ran zai kai kashi 50% na jimillar samar da wutar lantarki a duniya nan da shekarar 2050. Tunda shakar haske ta hanyar amfani da kayan hasken rana mai amfani da hasken rana ya fi faruwa ne a cikin kauri na wasu microns zuwa daruruwan microns, kuma tasirin saman kayan hasken rana kan aikin batir yana da matukar muhimmanci, ana amfani da fasahar fim mai kauri a cikin masana'antar tantanin halitta mai amfani da hasken rana.

Kwayoyin photovoltaic masu masana'antu galibi an raba su zuwa rukuni biyu: ɗaya shine ƙwayoyin hasken rana na silicon mai siffar crystalline, ɗayan kuma shine ƙwayoyin hasken rana mai siffar thin-film. Sabbin fasahohin silicon mai siffar crystalline sun haɗa da fasahar passivation emitter da fasahar bayan cell (PERC), fasahar heterojunction cell (HJT), fasahar passivation emitter bayan surface full diffusion (PERT), da fasahar oxide-piercing contact (Topcn). Ayyukan fina-finai masu sirara a cikin ƙwayoyin silicon mai siffar crystalline sun haɗa da passivation, anti-reflection, p/n doping, da conductivity. Fasahar batirin bakin ciki ta manyan fina-finai sun haɗa da cadmium telluride, jan ƙarfe indium gallium selenide, calcite da sauran fasahohi. Ana amfani da fim ɗin azaman Layer mai ɗaukar haske, Layer mai sarrafa kansa, da sauransu. Ana amfani da fasahohin fim mai siffar thin-fine daban-daban wajen shirya fina-finai masu sirara a cikin ƙwayoyin photovoltaic.

Siffofin kayan aiki:

1. Ɗauki tsarin sassauƙa, wanda zai iya ƙara ɗakin bisa ga buƙatun aiki da inganci, wanda yake da sauƙi da sassauƙa;

2. Ana iya sa ido sosai kan tsarin samarwa, kuma ana iya bin diddigin sigogin tsarin, wanda ya dace a bi diddigin samarwa;

4. Ana iya dawo da kayan aiki ta atomatik, kuma amfani da na'urar sarrafawa zai iya haɗa hanyoyin farko da na ƙarshe, rage farashin aiki, babban matakin sarrafa kansa, ingantaccen aiki da adana makamashi.

Ya dace da Ti, Cu, Al, Cr, Ni, Ag, Sn da sauran ƙarfe na elemental, kuma an yi amfani da shi sosai a cikin kayan lantarki na semiconductor, kamar: substrates na yumbu, capacitors na yumbu, maƙallan yumbu na LED, da sauransu.
