Mu ishami ry’ikoranabuhanga rigezweho ry’amashanyarazi akoresha imirasire y’izuba, HJT (Heterojunction) na TOPCon (Tunnel Oxide Passivated Contact) ni byo byibanze ku nganda. Ariko, hamwe no gushyira ahagaragara ibikoresho bya perovskite, HJT ivanze na perovskite irimo kwitabwaho kubera ibyiza byayo bidasanzwe, ikaba ingingo ikomeye mu nganda zikoresha imirasire y’izuba. Iyi nkuru irasuzuma ibyiza bya HJT ivanze na perovskite kurusha TOPCon n’uburyo ubu buryo burimo gushyiraho ahazaza h’ikoranabuhanga rikoresha imirasire y’izuba.
1. Intangiriro ku ikoranabuhanga rya HJT
HJT izwiho gukoresha ikoranabuhanga ryayo mu guhindura amashanyarazi mu buryo buhanitse kandi ikora neza cyane mu bihe by'urumuri ruto. Ikora ihuriro ry'ibintu bitandukanye binyuze mu gushyira agace gato ka silikoni kadafite ishusho ku gice cya silikoni gikozwe mu buryo bwa crystalline, bigagabanya gusubiranamo kw'ubuso no kongera ingufu z'amashanyarazi zifunguye mu turemangingo hamwe n'umuyoboro w'amashanyarazi mu buryo bwa short-circuit.
2. Imbogamizi zijyanye n'ikoranabuhanga rya TOPCon
TOPCon igera ku guhindagurika kw'ubuso binyuze mu gushyira urwego rwa okiside n'urwego rwa silicon rwa polycrystalline ku buso bw'uturemangingo, bigabanya igihombo cyo gusubiranamo. Ariko, kugera ku musaruro mwiza hamwe na TOPCon bihura n'imbogamizi, zirimo inzira zigoye, imicungire y'ikiguzi, ndetse n'ingorane zo kunoza imikorere.
3. Uruhare rw'ibikoresho bya Perovskite
Ibikoresho bya Perovskite ni byiza cyane mu kongera imikorere myiza ya selile z'izuba bitewe n'uko zikoresha ingufu nyinshi mu gufata urumuri, icyuho cy'umugozi gishobora guhindurwa, ndetse n'uburyo bwo gutunganya ibisubizo. Mu guhuza perovskite n'ikoranabuhanga rya HJT, birashoboka gukoresha imikorere myiza ya HJT no kuyinoza binyuze mu miterere ya perovskite yo gufata urumuri mu buryo bwagutse.
4. Ibyiza bya HJT bivanze na Perovskite
a. Ubushobozi bwo guhindura amashanyarazi hakoreshejwe fotoelectric mu buryo bwiza cyane:Kongeramo perovskite byongera cyane uburyo uturemangingo twa HJT twitwara, byongera umubare w’uturemangingo twakozwe n’amafoto. Uturemangingo twa HJT, dufite ubushobozi bwo gukora neza bwa 27.5%, twamaze kurusha ikoranabuhanga rya PV risanzwe. Imiterere y’uruhererekane rw’amajwi, ihinduranya urwego rwa silikoni rudafite ishusho n’urukiramende, yongera ubushobozi bwo kwinjiza urumuri, ikongera ubushobozi bwo guhindura ingufu.
b. Ituze ryiza:Uturemangingo twa HJT ntabwo dutanga gusa imikorere myiza ahubwo tunatanga n’ubudahangarwa buhebuje. Imiterere ya HJT-perovskite ikomeza imikorere myiza mu gihe kirekire, bitandukanye na TOPCon-perovskite, nubwo ibiciro byayo ari bike, igorwa no guhuza HJT mu bijyanye n’imikorere myiza.
c. Uburyo bworoshye bwo gukora:Uburyo ibikoresho bya perovskite bishobora gutunganywa mu buryo bushoboka bigabanya ikiguzi cyo gukora, bikaba ari ingenzi mu kugabanya ikiguzi cy’amashanyarazi (LCOE). Uturemangingo twa HJT dufite kandi inyungu mu gukora, dukoresha ubwiyongere bw’umwuka w’ubushyuhe buke (CVD) kugira ngo dushyiremo utwenda twa silikoni tudafite ubushyuhe bwinshi, hagakurikiraho utwenda twa silikoni tudafite ubushyuhe bwinshi (TCO) hamwe n’utwenda twa silikoni tudafite ubushyuhe bwinshi (p-type cyangwa n-type). Ubu buryo bworoshye bugabanya ikiguzi kandi bukongera umusaruro ugereranije n’uburyo bwa TOPCon bwo gutera ubushyuhe bwinshi, byongera ikiguzi cyo gukora no guhindagurika k’ubwiza.
d. Umusaruro utangiza ibidukikije:Ibikoresho bya Perovskite bitanga uburyo bwo gukora ibintu bitangiza ibidukikije kuko bitarimo ibintu by’uburozi cyangwa ibidakunze kuboneka. Bitandukanye n’ibikoresho bimwe na bimwe bya PV bikenera ibintu biteza akaga nka lead cyangwa cadmium, perovskites nta burozi nk’ubwo, bigabanya ingaruka mbi ku bidukikije no ku buzima. Byongeye kandi, perovskites ntizishingikiriza ku bintu bidakunze kuboneka, ibyo bikaba bishobora kwangiza ibidukikije. Umusaruro wazo ukoresha ingufu nke, bigatuma imyuka ihumanya ikirere igabanuka.
Muri make, guhuza HJT na perovskite bigaragaza icyerekezo cyiza cyo guteza imbere ingufu za photovoltaic mu gihe kizaza, hamwe n'ibyiza byabyo mu gukora neza, gutuza, kugabanya ikiguzi, no kubungabunga ibidukikije biruta TOPCon mu buryo bwinshi.
