Kuvandudzwa kwesolar cell performance!
Sezvatinoziva tese, simba rezuva ndiro tsime guru resimba rechiedza. Silicon mapaneru anogona kushandura mwenje kuita magetsi, uye echinyakare tandem solar lithium mabhatiri anogona kuita izvi zvakanyanya nekutora mamwe mafungu echiedza.
Kwete izvozvo chete, vatsvakurudzi vakaona kuti kushandisa dual-series configuration, ihwo hutsva hunoshandiswa hunoshandisa tsika yesilicon-based uye imwe yero peroxide yakagadzirwa ne “series” yekubatanidza maitiro matsva, anogona kuunganidza simba rakawanda uye kubata Kuwanda kwemarara, kuratidzwa uye kwakapararira chiedza kubva pasi (chinonzi “albedo”) kuti chiwedzere zvakanyanya ikozvino yezvikamu zvakatevedzana solar cells.
Musi waNdira 11, 2021, International Cooperation Organisation, kusanganisira vaongorori kubva kuKing Abdullah University of Science and Technology (KAUST) uye UT Chikoro cheUinjiniya) vakaburitsa chinyorwa chakanzi “Kushanda Kwepamusoro Kwakavakirwa paBand Gap Engineering” mujenari Natural Energy. Peroxide/Double Monocrystalline Silicon Solar Cell” (EfficientbifacialmonolithicperovskitePaper/Silicontandemsolarcellsviabandgapineering) chinyorwa.
Iri bepa rinoratidza maitiro ese echikwata ekugadzira peroxide / silicon zvishandiso kuti zvipfuure iyo ikozvino inogamuchirwa kuita miganho yeakatevedzana masisitimu.
Nhengo dzechikwata dzakapedza tsvakiridzo iyi pamwe chete. Pakati pavo, Dr. Michele DeBastiani akaisa pfungwa yekutsvakurudza uye akaita chigadziro pamwe chete na alessandro j. Mirabelli.
Yunivhesiti yeToronto zvemagetsi nekombuta engineering postdoctoral shamwari YiHou, Bin Chen naAnand S. Subbiah vakagadzira iyo peroxide band gap, nepo Erkan Aydin naFurkan H. Isikgor vakagadzira tandem yepamusoro kuonana uye marongero.
Mhedziso yechidzidzo ichi ndeyekuti iyo yakapetwa kaviri-mativi monolithic peroxide/silicon tandem solar cell inoshandisa diffuse light albedo munzvimbo, uye kuita kuri nani pane kuya kwe single-sided peroxide/silicon tandem solar cell. Boka rekutsvagisa rakatanga kuzivisa mhedzisiro yebvunzo yekunze. Pasi pechiedza chezuva che AM 1.5g, simba rakasimbiswa rekushandura simba remativi maviri akatevedzana rakapfuura 25%, uye simba rekugadzira magetsi rakanga rakakwirira se26 mwcm-2.
Panguva imwecheteyo, vatsvakurudzi vakadzidza peroxide bhendi gap inodiwa kuti yakakwana ikozvino inoenderana pasi pezvakasiyana-siyana zvekuvhenekera uye albedo mamiriro ezvinhu, zvichienzaniswa nemaitiro embiru idzi mbiri-mativi mbiru dzakafumurwa kune albedo dzakasiyana, uye dzakapa kuenzanisa pakati pezviviri zveKuverenga simba. kugadzirwa munzvimbo ine mamiriro akasiyana ezvakatipoteredza.
Chekupedzisira, timu yakaenzanisa nzvimbo dzekunze dzekuyedza dzine divi rimwechete uye mbiri-mativi peroxidase/silicon tambo kuratidza kukosha kwakawedzerwa kwetandem duality kune nzvimbo dzine chaiyo yakakodzera albedo.
Muviri mukuru weiyo itsva tandem solar cell inoumbwa nesilicon layer uye peroxide layer. Panguva imwecheteyo, ivo vanosanganiswa nemamwe akawanda akawanda. Muzvinafundo Stefanan DeWolf akadaro. “Chinetso chikuru kuoma kwechigadzirwa chetandem. Pane zvinhu gumi neina zvinosanganisirwa, uye chinhu chimwe nechimwe chinofanirwa kunyatsogadziriswa kuti tifunge nezvesimba realbedo. “
akadaro Dr. Michele DeBastiani, munyori anotungamira wekudzidza. “Nekushandisa albedo, isu tave kukwanisa kugadzira mafungu akakwira kupfuura echinyakare bipolar membrane pasina kuwedzera kwemitengo yekugadzira.” Vanyori vechidzidzo ichi vanosanganisira Muzvinafundo Ted Sargent uye postdoctoral muongorori YiHou muDhipatimendi reMagetsi neComputer Engineering paYunivhesiti yeToronto.
yakaita tsvakiridzo pamusoro pekugona kwekutora chiedza chezuva chisina kunanga munguva yakapfuura, asi haina kuita bvunzo dzekuyedza. Pamusoro peYunivhesiti yeUinjiniya neTekinoroji, vaongorori veKing Abdullah University yeScience neTekinoroji (KAUST) vakabatanawo nevabatsiri kubva kuKarlsruhe Institute of Technology neYunivhesiti yeBologna kugadzirisa sainzi inodiwa kuisa chiedza chezuva musimba rekukohwa simba. yemamodule avo Uye matambudziko einjiniya.
Zvadaro, pasi pemamiriro ekunze, vakaedza masero ezuva maviri etandem uye vakawana hunyanzvi kupfuura chero yekutengesa silicon solar panels.
“Single bifacial silicon solar maseru ari kukurumidza kuwedzera chikamu chavo mumusika wePHOTOVOLTAIC nekuti anogona kupa 20% hukama hwekuita kuvandudzwa. Kushandisa nzira iyi mu peroxide / silane inogona kuva inoshanda kupfuura tsika nesilicon solar masero. Uye zvinogona kuderedza mutengo wezvigadzirwa. ” Purofesa Stefanan DeWolf akagumisa. DeWolf nevamwe vake vakagadzira tekinoroji iyi mukubatana nezvikwata muCanada, Germany, neItaly.
Mukupera kwebepa, vaongorori vakaratidza kuburikidza nekuedza nzira yekushandisa iyo yakapetwa-mativi chimiro kuvandudza mashandiro eiyo yese peroxide / silicon chimiro. Nekuda kwekushandisa yakamanikana peroxide bhendi gap, mudziyo zvimiro zvine läpinäkyvä shure electrodes anovimba albedo kuwedzera ikozvino chizvarwa chepasi sero uye panguva imwe chete kuwedzera chizvarwa chepamusoro peperoxide sero.
Uku kuwirirana kunowanikwa kune peroxides nebhendi gap re 1.59-1.62 eV. Kuenzaniswa ne-single-sided peroxide/silicon series, bromine content ndiyo iduku, saka kugadzikana kune chokuita nehalide segregation kunoderedzwa zvikuru. dambudziko. Chikwata chakaongorora mashandiro eiyo mativi maviri-maviri tandem chimiro mumiyedzo yemumunda, uye akafanotaura kubuda kwesimba kweaviri-mativi uye ega-side-tandem zvimiro pasi pemamiriro ekunze akasiyana.
Muzviitiko zvese izvi, tandem iri nani pane imwe-yakatarisana chimiro, iyo inoratidza chivimbiso cheiyi tekinoroji. Iri basa rinoratidza kukwanisa kwechikwata chitsva chepamusoro-soro masero ezuva anogona kushandisa kushandiswa kwepamusoro-soro asi teknolojia inodhura yekuvhara gaka ne 30mwcm-2PGD barrier.
Kubva pano, kumwe kuvandudzwa kwekuita kwemidziyo uye kuwedzera kwechiyero chetekinoroji ndiwo matanho anotevera ane musoro ekuunza tekinoroji iyi padyo nemusika wephotovoltaic.
Purofesa Christophe Ballif, mutungamiriri wePhotovoltaic Laboratory yeFederal Institute of Technology muLausanne, Switzerland, haana kutora chikamu muongororo iyi. Akati. “Iri bepa rinopa humbowo hwekutanga hwakajeka hwekuyedza kwechigadzirwa chine mativi maviri tandem. Kuongororwa kwehuwandu hwekuita kwakashumwa nevatsvaguri kwakakosha pakumisa michina yakagadzikana inodiwa kuti tekinoroji iyi ipinde mumusika mukuru. ”
