Gabatarwa zuwa fasahar fina-finai ta hasken rana na hotovoltaic

Bayan gano tasirin tasirin hoto a Turai a cikin 1863, Amurka ta yi tantanin halitta na farko na hoto tare da (Se) a cikin 1883. A cikin farkon zamanin, an fi amfani da ƙwayoyin photovoltaic a cikin sararin samaniya, soja da sauran fannoni. A cikin shekaru 20 da suka gabata, raguwar ƙima a cikin farashin sel na hotovoltaic ya haɓaka aikace-aikacen tartsatsi na hasken rana a duniya. A karshen 2019, jimlar shigar ikon hasken rana PV kai 616GW a duk duniya, kuma ana sa ran isa 50% na duniya jimlar wutar lantarki samar da 2050. Tun da sha na haske ta photovoltaic semiconductor kayan yafi faruwa a cikin kauri kewayon 'yan microns zuwa daruruwan microns, da kuma yi fim ne mai muhimmanci tasiri na baturi surface na batir, da kuma aikin batir yana da muhimmanci a kan fuskar bangon waya. ana amfani da shi sosai a masana'antar hasken rana.

Kwayoyin photovoltaic da aka ƙera masana'antu sun kasu kashi biyu: ɗaya shine sel siliki na hasken rana, ɗayan kuma sel na hasken rana na bakin ciki. The latest crystalline silicon cell fasahar sun hada da passivation emitter da backside cell (PERC) fasaha, heterojunction cell (HJT) fasaha, passivation emitter back surface full diffusion (PERT) fasaha, da oxide-huda lamba (Topcn) fasahar cell. Ayyukan fina-finai na bakin ciki a cikin ƙwayoyin siliki na crystalline sun haɗa da wucewa, anti-reflection, p / n doping, da haɓakawa. Fasahar batir na bakin ciki na yau da kullun sun haɗa da cadmium telluride, jan ƙarfe indium gallium selenide, calcite da sauran fasaha. An fi amfani da fim ɗin azaman haske mai ɗaukar haske, Layer conductive, da dai sauransu. Ana amfani da fasahar fina-finai daban-daban a cikin shirye-shiryen fina-finai na bakin ciki a cikin ƙwayoyin photovoltaic.

Zhenhuahasken rana photovoltaic shafi samar linegabatarwa:

Fasalolin kayan aiki:

1. Yi amfani da tsari na zamani, wanda zai iya ƙara ɗakin ɗakin bisa ga bukatun aiki da dacewa, wanda ya dace da sauƙi;

2. Za a iya sa ido sosai kan tsarin samarwa, kuma ana iya gano sigogin tsari, wanda ya dace don waƙa da samarwa;

4. Kayan kayan aiki na iya dawowa ta atomatik, kuma yin amfani da mai amfani zai iya haɗawa da tsoho da na baya matakai, rage farashin aiki, babban mataki na aiki da kai, babban inganci da ceton makamashi.

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