Ikirahuri cya kadmium telluride ni iki?

Icyatsi na karuboni nkeya nintego yiterambere ryiterambere mugihugu cyanjye ' s ' Gahunda yimyaka 14 yimyaka itanu ' , amashanyarazi ya Photovoltaque nimbaraga nyamukuru zo kugera kuriyi ntego. Muburyo bwo kwihuta kwiterambere ryinganda zifotora, Usibye ingirabuzimafatizo ya silicon ya silicon ikurura abantu benshi, bateri ya firime yoroheje ikoresheje kadmium telluride nkigice cyo kuyikuramo nayo yashishikaje inganda. 

Ikirahuri cya Cadmium telluride ni karubone nkeya, icyatsi, izigama ingufu, irema ingufu, ibidukikije byangiza ibidukikije kandi bifite umutekano mushya nibikoresho bishya, Byombi ni ibikoresho byubaka icyatsi nisoko ryingufu zisukuye, Ifite ibintu bisanzwe biranga ibirahuri byubatswe, Byiza kandi byiza, uburyo butandukanye, kubyara ingufu nkeya, Guha imbaraga inyubako, 'Guhindura isi ' karubone '

Cadmium telluride (CdTe) nigikoresho cyingenzi cya II-VI cyunganira igice cya kabiri , Imiterere ni umukara wa kirisiti yumukara cyangwa ifu, Ingingo yo gushonga igera kuri 1092 ℃ , Uburemere bwa molekile 240, Imiterere ya kristu ni ubwoko bwa sphalerite, Ifite imiterere yingufu zingirakamaro. Umuyoboro wacyo uhoraho ni 0.6481nm, Ubugari bwa bandgap ni 1.45eV, Ubushyuhe bwicyumba cya elegitoronike ni 1050 c ㎡ / (Vs), Icyumba cyubushyuhe bwicyumba cyari 80 c ㎡ / (Vs).

Ingufu zubusabane bwimiti ya kadmium telluride iri hejuru ya 5.7eV, Nimwe mubintu bya chemosynetique bihamye byimiterere ya kadmium muri kamere. Kubwibyo, kadmium telluride ihagaze neza mubushyuhe bwicyumba, kandi ntigishobora gukomera mumazi, acide nkeya, Ni umutekano muke mugihe cyo gukora inganda no kuyikoresha.

Twabibutsa ko, Igisubizo cyerekana imirasire y'izuba ya kadmium telluride ihuye cyane no gukwirakwiza izuba ku isi, Ubushobozi bwo gutanga ingufu burakomeye.

Cadmium telluride ifite imikorere ihamye, coefficente yo gukwirakwiza ingufu z'umucyo mwinshi, N-ubwoko bwa P cyangwa se P-semiconductor ibikoresho birashobora kuboneka mugukwirakwiza imyanda itandukanye, Irashobora gukoreshwa mugukora ibyuma byerekana imirasire ya kirimbuzi (kugirango ikoreshwe mubuvuzi), moderi ya infrarafrica-optique, insimburangingo ya infragre, idirishya nibindi bikoresho. Mu murima wa Photovoltaque, Cadmium telluride ifatwa nkibikoresho byingenzi byo gutegura ingirabuzimafatizo nini nini ya firime. Filime ya kadmium telluride ifite umubyimba wa m2 2 gusa (micron), Igipimo cyo kwinjiza optique kirenga 90% mugihe gisanzwe cya AM1.5, Uburyo bwiza bwo guhindura ibintu bugera kuri 33%, Kubwibyo, ingufu zizuba zahindutse ikibanza kinini cyo gukoresha kuri kadmium telluride. Mubisanzwe, inganda zifotora zisaba gukoresha kadmium telluride ifite ubuziranenge bwa 5N.

Ugereranije nizindi selile zuba, Imiterere ya kadmium telluride yoroheje ya firime izuba ryoroshye biroroshye; Muri rusange, Imiterere gakondo igizwe na etage eshanu, Nukuvuga, substrate yikirahure, icyerekezo cya oxyde oxyde (TCO layer), cadmium sulfide (CdS) idirishya ryamadirishya, cadmium telluride (CdTe) igorofa, igahuza inyuma na electrode yinyuma, Nkuko bigaragara mumashusho hepfo.

Uko gahunda ya politiki y’imbere mu kubaka ingufu zigenda ziyongera buhoro buhoro,  guverinoma ishimangira kubaka ingufu zikoreshwa mu kongera ingufu. Niba intego ebyiri-karubone zigomba kubahirizwa, Ntizishobora gutandukana ninzira yingenzi yo kubaka amafoto yerekana amashanyarazi (BIPV).

2020, Minisiteri ishinzwe imiturire n’ubwubatsi mu Bushinwa n’izindi minisiteri na komisiyo zirindwi zasohoye gahunda z’ibikorwa bijyanye n’inyubako y’icyatsi, Gahunda igamije kugera kuri 70% y’inyubako nshya z’icyatsi kibisi mu 2022, Irasabwa kuyobora imishinga y’ishoramari rya leta gufata iyambere mu gukoresha ibikoresho byubaka icyatsi. Cadmium telluride yamashanyarazi yububiko bwibirahure byateguwe binyuze muri kadmium telluride yoroheje ya firime ya batiri, Nibisekuru bishya byibikoresho byubaka.

Ugereranije na sisitemu ya silicon ya kristaline,  Cadmium telluride yoroheje ya firime modules ifite ibiranga coeffisente yo kwinjirira cyane, ingaruka zishyushye ntoya, ingaruka nziza nkeya-yumucyo, ubwiza buhebuje, hamwe no kwihindura bikomeye, 

Irashobora gukoreshwa muburyo bwububiko butandukanye nko kubaka ibisenge hamwe nurukuta rwumwenda, Kongera ahantu heza h’amashanyarazi hifashishijwe cyane cyane ubuso bwinyubako, Guhuza ingufu zingufu zinyubako zikenewe, Byanyuma bikagabanya imyuka yubaka imyuka iva mumasoko. Bitewe na politiki nziza, Icyifuzo cya kadmium telluride yoroheje ya firime yerekana amashusho azakomeza kwaguka mugihe kizaza.
