Muna 2009, apo calcite yakaonda-firimu maseru akatanga kuoneka shanduko yekushandura yaingova 3.8%, uye yakawedzera nekukurumidza, Unit 2018, kushanda kwerabhoritari kwakapfuura 23%. The basic molecular formula ye chalcogenide compound iABX3, uye A position inowanzoita ioni yesimbi, yakadai seCs+ kana Rb+, kana boka rinoshanda. Zvakadai se(CH3NH3;), [CH (NH2)2]+; B chinzvimbo kazhinji divalent cations, akadai Pb2+ uye Sn2+ ions; X chinzvimbo kazhinji halogen anions, akadai Br-, I-, Cl-. Nekushandura zvikamu zvemakomponi, iyo inorambidzwa bandwidth yechalcogenide yakasanganiswa inogadziriswa pakati pe1.2 uye 3.1 eV. Iyo yepamusoro-soro yephotovoltaic kutendeuka kwechalcogenide masero papfupi-wavelengths, akaiswa pamusoro pemaseru ane yakanakisa kutendeuka kwekuita pahurefu-wavelengths, senge heterogeneous crystalline silicon masero, anogona ne theoretically kuwana photovoltaic kutendeuka kunobudirira kweanopfuura 30%, kutyora muganho weiyo theoretical crystal masero. 2020, bhatiri iri rakaturikidzana rakatowana shanduko inoshanda ye29.15% muBerlin Laboratory yeHeimholtz, Germany, uye chalcogenide-crystalline silicon Stacked cell inoonekwa seimwe yehukuru hwebhatiri tekinoroji yechizvarwa chinotevera.
Iyo chalcogenide film layer yakaonekwa nenzira ine-matanho maviri: yekutanga, porous Pbl2, uye CsBr mafirimu akaiswa pamusoro pemaseru heterojunction ane fluffy surface by co-evaporation, ndokuzofukidzwa ne organohalide solution (FAI, FABr) ne spin-coating. Iyo organic halide solution inopinda mumapores emhute-yakaiswa inorganic firimu yobva yaita nekupenya pa150 degrees Celsius kuita chalcogenide film layer. Ukobvu hwefirimu rechalcogenide rakawanikwa raive 400-500 nm, uye raive rakabatana munhevedzano neseri kweheterojunction sero kukwirisa kuenzanirana kwazvino. Iwo maelectronic transport layers pa chalcogenide firimu iLiF neC60, akawanikwa achitevedzana neanopisa mhute deposition, achiteverwa neatomic layer deposition yebuffer layer, Sn02, uye magnetron sputtering yeTCO seyakajeka yekumberi electrode. Kuvimbika kweiyo sero yakaturikidzana iri nani pane yechalcogenide single-layer cell, asi kugadzikana kwechalcogenide firimu pasi pemamiriro ekunze emhute yemvura, chiedza, uye kupisa kuchiri kuda kuvandudzwa.
