Ikoranabuhanga ryizuba rya Cadmium telluride (CdTe) nuyoboye ingufu zizuba zoroshye. Ikora neza kuko ifite imiterere yihariye yibikoresho. Ibi bifasha guhindura urumuri rwizuba mumashanyarazi neza. Imirasire y'izuba ya CdTe ifite intera ya bande ya 1.45 eV. Bafite kandi coefficente yo kwinjiza cyane ya cm 10 ^ 6 cm ^ -1. Ibi bivuze ko bashobora guhindura byihuse urumuri rwizuba mububasha. Buri module ikoresha kg 0,065 gusa yibikoresho bya selile. Kubikora bikenera 59 kWh y'amashanyarazi. Ibi bintu bituma kadmium telluride (CdTe) ikoranabuhanga ryizuba rihendutse kandi ryihuse gukora. Ni amahitamo meza kubyo ingufu zikenewe muri iki gihe.
Imirasire y'izuba ya Cadmium telluride (CdTe) ikoresha urwego ruto rw'ibikoresho bidasanzwe. Ibi bikoresho bifasha guhindura urumuri rw'izuba amashanyarazi. Ibyo babikora muburyo bukora neza kandi buhendutse. Utugingo ngengabuzima twizuba dufite igishushanyo mbonera. Igishushanyo kibafasha gufata urumuri rwizuba. Irabafasha kandi gukora imbaraga nyinshi. Ibi bituma selile zikomeye kandi zizewe. CdTe imirasire yizuba igura make gukora. Bakoresha imbaraga nke. Bakora neza ahantu hashyushye, huzuye ibicu, cyangwa ahantu hakeye. Bakora neza kuruta panike ya silicon muribi bihe. Bimara imyaka irenga 25. Birashobora gukoreshwa neza. Bafite kandi ingaruka ntoya kubidukikije. Ibi bituma bahitamo ubwenge bwingufu zisukuye. Ikoranabuhanga rya CdTe riratera imbere byihuse. Ikoreshwa mumirima minini yizuba ninyubako zubucuruzi. Irakoreshwa kandi muburyo bushya bwo kubaka. Hano haribintu bishimishije bizaza biza vuba.
CdTe yoroheje ya firime yizuba ifite ibice byegeranye hejuru yundi. Buri cyiciro gikora akazi kihariye ko gufasha gukora amashanyarazi aturuka ku zuba. Igishushanyo gikunze kwitwa superstrate iboneza. Muri iki gishushanyo, urumuri rwinjira muburyo busobanutse imbere. Ibice nyamukuru ni oxyde ikora neza, idirishya ryidirishya, imashini ya kadmium telluride, hamwe ninyuma. Ibishushanyo bimwe bishya bifashisha ibice bibiri byo gufata kugirango bifate urumuri rwizuba.
Abahanga bakoze uburyo bushya bwo kubaka izo selile. Bakoresha ibyuma byoroshye bya CdTe, bongeramo ibice bya tellurium inyuma, kandi bakora selile bilayeri hamwe na CdSeTe. Izi mpinduka zifasha selile gukora byinshi bigezweho na voltage. Bafasha kandi selile gukora neza muri rusange.
Hano hari imbonerahamwe yerekana bimwe byingenzi ibikoresho byububiko bwibikoresho :
| Ibikoresho byububiko bushya | Ibipimo ngenderwaho / Imikorere Ibipimo | Byibanze Ibisubizo / Ingaruka |
|---|---|---|
| Gutoya CdTe Absorbers (0.4 - 1.0 µm umubyimba) | Imikorere irenga 10% (0.4 µm), 15% (1.0 µm); yitwaye neza IV | Ibikoresho byoroheje bigura make kandi bigakomeza voltage nziza |
| Tellurium (Te) Igice Kuri Inyuma | Umuvuduko uri hejuru ya 1 V ku bushyuhe bwo hasi | Guhuza neza inyuma bifasha selile gukora voltage nyinshi |
| Bilayer CdSeTe / Te selile | +2 mA / cm² ikigezweho, voltage imwe igabanuka, PL nziza | Ibindi bigezweho kandi byiza Photoluminescence |
| MgZnO Imbere-Imigaragarire ya Buffer | Electron nyinshi hamwe na Ga doping | Ikibanza kinini cyo gutandukanya icyuma kireka urumuri rwinshi |
Imirasire y'izuba ya CdTe yateye imbere ikoresha imiterere ya tandem. Ibi bivuze ko batondekanya selile yo hejuru ya CdTe na selile yo hepfo ya FeSi2. Ingirabuzimafatizo zombi zahujwe na tunnel. Igishushanyo kirashobora kugera kubikorwa byiza cyane. Tandem selile zimwe zirashobora guhaguruka 44.5% gukora neza mubizamini.
CdTe firime yoroheje izuba ikoresha ibikoresho bike byingenzi. Igice nyamukuru gikurura ibintu gikozwe muri kadmium telluride. Ibi bikoresho nibyiza kumira izuba. Idirishya ryubusanzwe ni kadmium sulfide. Irekura urumuri rworoshye ariko ikabuza kwishyurwa udashaka. Ibishushanyo bishya bimwe bikoresha indium sulfide cyangwa magnesium zinc oxyde kubisubizo byiza. Guhuza imbere ni okiside ikora neza, nka tin oxyde cyangwa indium tin oxyde. Uru rupapuro rutanga urumuri kandi rutwara amashanyarazi.
Ubushakashatsi bwerekana ko ubwiza bwibi bikoresho ari ngombwa. Microstructure ya polycrystalline yoroshye murwego rwa CdTe ifasha selile gukora neza. Kurwanya shunt murwego rwo hejuru bituma selile ikora neza, nubwo itaba nziza cyane hanze. Idirishya rya CdS rigomba kuba ryoroshye kandi ridafite inenge. Ibi bifasha urumuri rw'izuba guhinduka amashanyarazi. Imbere ya electrode igomba kugira imbaraga nke kugirango ihagarike gutakaza ingufu, cyane cyane izuba ryinshi. Ihitamo nubugenzuzi bifasha tekinoroji ya CdTe gukora neza kuruta izindi selile zuba zoroshye cyane mubihe byinshi.
CdTe yoroheje-firime yizuba ikoresha semiconductor kugirango ihindure urumuri rwizuba mumashanyarazi. Iyo urumuri rw'izuba rukubise ingirabuzimafatizo, urwego rwa CdTe rwinjiza mu mucyo. Izi mbaraga zituma electron zigenda kandi zigakora electron-umwobo. Umuriro w'amashanyarazi kumasangano ya pn utandukanya ayo mafaranga. Electron ijya imbere. Imyobo ijya inyuma. Uru rugendo rukora amashanyarazi. Ibiriho birashobora guha imbaraga ibintu cyangwa kujya muri gride.
Uburyo selile yubatswe nibikoresho byakoreshejwe bigira ingaruka kuburyo ikora. Kurugero, ubunini bwurwego rwa CdTe, urwego rwa doping, hamwe nubwiza bwitumanaho byose. Imbonerahamwe ikurikira irerekana ibintu byingenzi byerekeranye ningirabuzimafatizo ya CdTe isanzwe: Agaciro

CdTe yoroheje ya firime izuba irashobora gukomeza hafi 70-80% yubushobozi bwabo busanzwe no mumucyo muto. Ibi bituma bahitamo neza kubikoresha byinshi. Kuvanga ibishushanyo mbonera, ibikoresho byiza, hamwe na semiconductor idasanzwe bifasha tekinoroji yizuba ya kadmium telluride itanga ingufu zizuba zikomeye kandi zizewe.
Ababikora bakurikiza intambwe nke zo gukora izo selile. Batangirana ikirahure cyangwa urufatiro rworoshye. Noneho, bashira kumurongo usobanutse ureka urumuri kandi rugatwara amashanyarazi. Nyuma yibyo, bongeramo idirishya rito ryakozwe muri kadmium sulfide. Ibikurikira, bashira kumurongo nyamukuru winjiza bakoresheje ifu ya CdTe. Bakoresha uburyo nka sputtering cyangwa chimique de pompe kuriyi ntambwe. Ibigo bimwe bikora CdTe kristu ikoresheje uburyo bwihariye bwo gukonjesha. Izi ntambwe zubaka ibice bihindura urumuri rwizuba imbaraga. Imishinga minini, nka Solar ya 457 MW itumiza, yerekana uburyo izo panne zishobora gukorwa vuba. Inkunga ya guverinoma nubushakashatsi bifasha gukora izo selile zihendutse kandi nziza.
Inzira yoroheje ya firime ikoresha ibikoresho ningufu nkeya kuruta panike ya silicon. Ibi bituma byihuta kandi byiza kubidukikije.
CdTe yoroheje ya firime izuba ikenera kadmium na tellurium. Byombi biva mubikoresho bisigaye biva mu bucukuzi. Ibi bifasha kugabanya imyanda. Imbonerahamwe ikurikira iratanga amakuru yingenzi yerekeye aho ibyo bikoresho biva nuburyo bikoreshwa:
