Njengoba sonke sazi, amandla elanga angumthombo oyinhloko wamandla okukhanya. Amaphaneli e-silicon angaguqula ukukhanya kube ugesi, futhi amabhethri e-lithium endabuko e-tandem elanga angenza lokhu ngempumelelo ngokumunca ubude obungeziwe bokukhanya.

Akukhona lokho kuphela, abacwaningi baye baqaphela ukuthi ukusebenzisa ukucushwa kwe-dual-series, kuwuhlelo olusha olusebenzisa i-silicon-based yendabuko kanye nolunye ungqimba lwe-peroxide eyenziwe ngokuhlanganiswa “kochungechunge” lwezinhlelo ezintsha, ezingaqoqa amandla amaningi futhi bamba Ukukhanya okuningi okumoshiwe, okubonisiwe nokuhlakazekile okuvela phansi (okuthiwa “i-albedo”) ukuze kwandiswe ngokuphawulekayo kwamanje kochungechunge lwamaseli elanga.

Ngomhla ziyi-11 kuMasingana 2021, i-International Cooperation Organization, okuhlanganisa nabacwaningi abavela e-King Abdullah University of Science and Technology (KAUST) kanye ne-UT School of Engineering) bashicilele isihloko esithi “High Efficiency Based on Band Gap Engineering” kujenali Amandla Emvelo. I-Peroxide/Double Monocrystalline Silicon Solar Cell” (I-EfficientbifacialmonolithicperovskitePaper/Silicontandemsolarcellsviabandgapineering).

Leli phepha libonisa yonke inqubo yethimba yokuklama amadivayisi e-peroxide/silicon ukuze eqe imikhawulo yokusebenza eyamukelwe njengamanje yokucushwa kochungechunge.

Amalungu ethimba aqede lolu cwaningo ndawonye. Phakathi kwabo, uDkt. Michele DeBastiani ubeke umbono wocwaningo futhi wenza idivayisi kanye no-alessandro j. Mirabelli.

Ozakwethu be-University of Toronto electronic and computer postdoctoral ozakwethu u-YiHou, u-Bin Chen no-Anand S. Subbiah bathuthukise igebe lebhendi ye-peroxide, kuyilapho u-Erkan Aydin noFurkan H. Isikgor bathuthukisa ukuthintana okuphezulu kwe-tandem nesakhiwo.

Isiphetho salolu cwaningo ukuthi i-monolithic peroxide/silicon tandem solar cell enezinhlangothi ezimbili zisebenzisa ukukhanya kwe-albedo okusabalale endaweni ezungezile, futhi ukusebenza kungcono kunokweseli elinohlangothi olulodwa lwe-peroxide/silicon tandem solar. Ithimba labacwaningi liqale labika imiphumela yokuhlolwa kwangaphandle. Ngaphansi kokukhanya kwelanga okukodwa kwe-AM 1.5g, ukuguqulwa kwamandla okuqinisekisiwe kochungechunge olunezinhlangothi ezimbili kudlule u-25%, futhi ukuminyana kokukhiqizwa kwamandla kwakuphezulu njengokungu-26 mwcm-2.

Ngasikhathi sinye, abacwaningi bafunda igebe lebhendi ye-peroxide edingekayo ukuze kufane kwamanje okufanelekile ngaphansi kwezimo ezihlukahlukene zokukhanya kwangempela kanye nezimo ze-albedo, kuqhathaniswa izici zalezi zinsika ezinamaceleni amabili ezivezwe ku-albedo ehlukene, futhi zanikeza ukuqhathanisa phakathi kwemiphumela emibili yokubala yamandla. ukukhiqizwa endaweni enezimo zemvelo ezahlukene.

Ekugcineni, ithimba liqhathanise izindawo zokuhlola zangaphandle ezinezintambo zohlangothi olulodwa nezinhlangothi ezimbili ze-peroxidase/silicon ukuze libonise inani elingeziwe le-tandem duality ezindaweni ezine-albedo yangempela efanele.

Umzimba oyinhloko weseli entsha ye-tandem yelanga yakhiwe ungqimba lwe-silicon kanye nongqimba lwe-peroxide. Ngesikhathi esifanayo, zihlanganiswa nezinye izinhlanganisela eziningi. Kusho uSolwazi Stefanan DeWolf. “Inselelo enkulu ubunkimbinkimbi bomshini we-tandem. Kukhona izinto ezingu-14 ezihilelekile, futhi impahla ngayinye kufanele yenziwe kahle ukuze icabangele ithonya le-albedo. “

kusho uDkt. Michele DeBastiani, umbhali ohamba naye kulolu cwaningo. “Ngokusebenzisa i-albedo, manje sesingakwazi ukukhiqiza imisinga ephakeme kakhulu kune-bipolar membranes ngaphandle kokukhuphuka kwezindleko zokukhiqiza.” Ababhali balolu cwaningo bahlanganisa uSolwazi Ted Sargent kanye nomcwaningi we-postdoctoral u-YiHou eMnyangweni Wezobunjiniyela Bakagesi Nekhompyutha eNyuvesi yaseToronto.

wenze ucwaningo mayelana namandla okuthwebula ukukhanya kwelanga okungaqondile esikhathini esidlule, kodwa akazange enze ukuhlola kokuhlola. Ngaphezu kweNyuvesi Yezobunjiniyela Nezobuchwepheshe, abacwaningi baseKing Abdullah University of Science and Technology (KAUST) baphinde babambisana nabahlanganyeli abavela eKarlsruhe Institute of Technology kanye naseNyuvesi yaseBologna ukuxazulula isayensi edingekayo ukuze kufakwe ukukhanya kwelanga okungaqondile emandleni okuvuna amandla. zamamojula wabo Kanye nezinselele zobunjiniyela.

Bese, ngaphansi kwezimo zangaphandle, bahlole amaseli elanga e-tandem anezinhlangothi ezimbili futhi bathola ukusebenza kahle ukudlula noma yimaphi amaphaneli elanga e-silicon okuhweba.

“Amaseli elanga e-silicon e-bifacial e-solar akhulisa ngokushesha isabelo sawo emakethe ye-PHOTOVOLTAIC ngoba anganikeza ukuthuthukiswa kokusebenza okuhlobene okungama-20%. Ukusebenzisa le ndlela ku-peroxide/silane kungasebenza kangcono kunamaseli elanga e-silicon yendabuko. Futhi kunganciphisa izindleko zezinto ezingavuthiwe.” UProfesa Stefanan DeWolf waphetha. UDeWolf nozakwabo bathuthukise lobu buchwepheshe ngokubambisana namaqembu aseCanada, eJalimane nase-Italy.

Ekuphetheni kwephepha, abacwaningi bafakazele ngokuhlolwa ukuthi bangasisebenzisa kanjani isici esinezinhlangothi ezimbili ukwenza ngcono ukusebenza kwesakhiwo sonke se-peroxide/silicon. Ngenxa yokusetshenziswa kwegebe lebhande le-peroxide elincane, izakhiwo zedivayisi ezinama-electrode angemuva asobala zithembele ku-albedo ukuze kwandiswe isizukulwane samanje sengqamuzana eliphansi futhi ngesikhathi esifanayo andise isizukulwane samanje seseli ephezulu ye-peroxide.

Lokhu kufanisa kufinyelelwa kuma-peroxides ngegebe lebhande lika-1.59-1.62 eV. Uma kuqhathaniswa nochungechunge olunohlangothi olulodwa lwe-peroxide/silicon, okuqukethwe kwe-bromine kuncane kakhulu, ngakho ukuzinza okuhlobene nokuhlukaniswa kwe-halide kuncipha kakhulu. inkinga. Ithimba lihlole ukusebenza kwesakhiwo se-tandem esinezinhlangothi ezimbili ezivivinyweni zenkambu, futhi labikezela ukuphuma kwamandla kwesakhiwo se-tandem esinezinhlangothi ezimbili nezinohlangothi olulodwa ngaphansi kwezimo zezulu ezihlukene.

Kuzo zombili izimo, i-tandem ingcono kunesakhiwo sohlangothi olulodwa, okubonisa isithembiso salobu buchwepheshe. Lo msebenzi ubonisa amandla ekilasi elisha lamaseli elanga asebenza kahle kakhulu angasebenzisa ubuchwepheshe bokusebenza okuphezulu kodwa obungabizi kakhulu ukuvala igebe ngesithiyo esingu-30mwcm-2PGD.

Ukusuka lapha, ukuthuthukiswa okuqhubekayo kokusebenza kwemishini kanye nokwandiswa kwesikali sobuchwepheshe yizinyathelo ezilandelayo ezinengqondo zokusondeza lobu buchwepheshe emakethe ye-photovoltaic.

USolwazi Christophe Ballif, umqondisi we-Photovoltaic Laboratory ye-Federal Institute of Technology eLausanne, eSwitzerland, akazange ahlanganyele kulolu cwaningo. Uthe. “Leli phepha linikeza ubufakazi bokuqala obucacile bokuhlola idivayisi ye-tandem enezinhlangothi ezimbili. Ukuhlaziywa komthamo wokusebenza okubikwe ngabacwaningi kubaluleke kakhulu ekutholeni imishini ezinzile edingekayo ukuze lobu buchwepheshe bungene emakethe enkulu. ”
