Ikirahure 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 silikaline ikurura abantu benshi, Batteri ya firime yoroheje ikoresheje kadmium telluride nkurwego rwimitsi nayo yakwegereye inganda. 

Ikirahuri cya Cadmium telluride ni ikirahure gito, icyatsi, kizigama ingufu, kirema ingufu, cyangiza ibidukikije kandi gifite umutekano mushya hamwe nibikoresho bishya, Byombi ni ibikoresho byubaka icyatsi n’isoko ry’ingufu zisukuye, Ifite ibintu bisanzwe biranga ibirahuri byubatswe, Byiza kandi byiza, uburyo butandukanye, kubyara amashanyarazi make, Guha imbaraga inyubako, 'Guhindura isi neza ' '

Cadmium telluride (CdTe) ningirakamaro ya II-VI igizwe ningingo ya semiconductor , Imiterere ni ibice byumukara wa kirisiti cyangwa ifu, aho gushonga bigera kuri 1092 ℃ , Uburemere bwa molekuline 240, Imiterere ya kirisiti 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 mumyanya ya chemosynetique ihamye yibintu bya kadmium muri kamere. Kubwibyo, kadmium telluride ihagaze neza mubushyuhe bwicyumba, kandi ntigishobora gukama mumazi, acide nkeya, Ni umutekano muke mugihe cyo gukora inganda no kuyikoresha.

Twabibutsa ko, Igisubizo cyizuba cyizuba cya kadmium telluride gihuye neza nogukwirakwiza izuba kwisi kwisi, Ububasha bwo gutanga ingufu burakomeye.

Cadmium telluride ifite imikorere ihamye, coefficente yo gukwirakwiza ingufu z'umucyo mwinshi, N-cyangwa se ubwoko bwa P-semiconductor ibikoresho birashobora kuboneka mugukuraho imyanda itandukanye, Irashobora gukoreshwa mugukora ibyuma byerekana imirasire ya kirimbuzi (kugirango ikoreshwe mubuvuzi), moderi ya infrarafrica optique, insimburangingo ya infragre, idirishya hamwe 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 2 μ m 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, inyuma yinyuma hamwe 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 yiyongereye ku buryo bugaragara. Niba intego ebyiri-karubone zigomba kubahirizwa, Ntizishobora gutandukana ninzira yingenzi yo kubaka amafoto yerekana amashanyarazi (BIPV).

2020, Minisiteri ishinzwe imiturire n’ubwubatsi mu Bushinwa hamwe na minisiteri na komisiyo zirindwi zasohoye gahunda z’ibikorwa bijyanye n’inyubako y’icyatsi, Gahunda igamije kuzuza 70% y’inyubako nshya z’icyatsi 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 silisiki ya kirisiti,  Cadmium telluride yoroheje ya firime modules ifite ibiranga coeffisente yo kwinjirira cyane, ingaruka zishyushye ntoya, ingaruka nziza-ntoya, ubwiza buhebuje, hamwe no kwihindura, 

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, Ibisabwa kuri kadmium telluride yoroheje ya firime yerekana amashusho azakomeza kwaguka mugihe kizaza.
