Tekinoroji Yekuputira muCalcitonite Solar Cells

Muna 2009, apo masero e calcite thin-film akatanga kuoneka, kushanda kwekushandura kwaive 3.8% chete, uye kwakawedzera nekukurumidza, Unit 2018, kushanda kwerabhoritari kwakapfuura 23%. Fomura yekutanga yemolecular ye chalcogenide compound iABX3, uye chinzvimbo cheA chinowanzova metal ion, senge Cs+ kana Rb+, kana boka re organic functional. Sezvakaita (CH3NH3;), [CH (NH2)2]+; B chinzvimbo chinowanzova divalent cations, senge Pb2+ uye Sn2+ ions; X chinzvimbo chinowanzova halogen anions, senge Br-, I-, Cl-. Nekuchinja zvikamu zvemakomputa, bandwidth inorambidzwa yemakomputa e chalcogenide inogadziriswa pakati pe1.2 ne3.1 eV. Kushandurwa kwemasero echalcogenide ne photovoltaic kunoshanda zvakanyanya pahurefu hwemafungu mapfupi, akaiswa pamasero ane mashandiro akanaka ekushandura pahurefu hwemafungu marefu, akadai semasero esilicon ane crystalline akasiyana-siyana, anogona kuwana mashandiro ekushandura e photovoltaic anopfuura 30%, achipfuura nemuganho wekushanda kwekushandura kwe crystalline silicon cells kwe29.4%. 2020, bhatiri iri rakaiswa muzvikamu rakatowana kushanda kwekushandura kwe29.15% muBerlin Laboratory yeHeimholtz, Germany, uye chalcogenide-crystalline silicon Stacked cell inoonekwa seimwe yehunyanzvi hukuru hwemabhatiri echizvarwa chinotevera.

Rutivi rwefirimu rechalcogenide rwakaonekwa nenzira ine matanho maviri: kutanga, mafirimu ePbl2, neCsBr ane maburi akaiswa pamusoro pemasero eheterojunction ane nzvimbo dzakapfava kuburikidza ne co-evaporation, uye akazofukidzwa ne organohalide solution (FAI, FABr) ne spin-coating. Mhinduro ye organic halide inopinda mumaburi efirimu re inorganic rakaiswa ne vapor uye yozosangana uye inonamira pa 150 degrees Celsius kuti igadzire rutivi rwefirimu rechalcogenide. Ukobvu hwefirimu rechalcogenide hwakawanikwa hwaive 400-500 nm, uye yakabatana ne heterojunction cell iri pasi kuti iwedzere kuenderana kwe current. Ma electron transport layers pafirimu rechalcogenide ndiLiF neC60, anowanikwa sequentially ne thermal vapor deposition, ichiteverwa ne atomic layer deposition ye buffer layer, Sn02, uye magnetron sputtering yeTCO se transparent front electrode. Kuvimbika kwesero iri rakaunganidzwa kuri nani pane kwesero rechalcogenide rine layer imwe chete, asi kugadzikana kwefirimu rechalcogenide pasi pesimba remhepo, chiedza, uye kupisa kuchiri kufanira kuvandudzwa.
