Ngo-2009, xa iiseli ze-calcite ezibhityileyo zefilimu zaqala ukubonakala ukusebenza kakuhle kokuguqulwa kwaba yi-3.8% kuphela, kwaye kwanda ngokukhawuleza, i-Unit 2018, ukusebenza kakuhle kwelebhu kudlule i-23%. Isiseko se-molecular formula ye-chalcogenide compound yi-ABX3, kwaye i-A isikhundla ngokuqhelekileyo i-ion yensimbi, njenge-Cs + okanye i-Rb +, okanye iqela elisebenzayo lezinto eziphilayo. Njenge (CH3NH3;), [CH (NH2)2]+; Indawo ye-B idla ngokuba yi-divalent cations, njenge-Pb2+ kunye ne-Sn2+ ions; Indawo ye-X idla ngokuba yi-halogen anion, njenge-Br-, I-, Cl-. Ngokutshintsha amacandelo e-compounds, i-bandwidth engavumelekanga ye-chalcogenide compounds ilungiswa phakathi kwe-1.2 kunye ne-3.1 eV. Ukuguqulwa kwe-photovoltaic ephezulu yeeseli ze-chalcogenide kubude obufutshane, obubekwe phezulu kwiiseli ezinokuguqulwa okugqwesileyo kumanqanaba amade amade, njengeeseli ze-silicon ze-crystalline ze-heterogeneous, zinokuthi zifumane i-photovoltaic yokuguqulwa kwe-photovoltaic engaphezulu kwe-30%, iphule umda we-conversion ye-crystalline ye-conversion ye-container ye-conduct4. Ngo-2020, le bhetri igciniweyo sele iphumelele uguqulo olusebenzayo lwe-29.15% kwiLebhu yaseBerlin yaseHeimholtz, eJamani, kunye ne-chalcogenide-crystalline silicon Iseli egciniweyo ithathwa njengenye yetekhnoloji enkulu yebhetri yesizukulwana esilandelayo.
Ifilimu ye-chalcogenide yefilimu yaqatshelwa ngendlela yamanyathelo amabini: okokuqala, i-Pbl2 e-porous, kunye neefilimu ze-CsBr zafakwa kumphezulu weeseli ze-heterojunction kunye neendawo ezithambileyo ngokunyuka kwe-co-evaporation, kwaye emva koko zigqunywe ngesisombululo se-organohalide (FAI, FABr) nge-spin-coating. Isisombululo se-organic halide singena kwi-pores yefilimu ye-inorganic efakwe ngumphunga kwaye emva koko iphendule kwaye ikhanye kwi-150 degrees Celsius ukwenza umaleko wefilimu ye-chalcogenide. Ubukhulu befilimu ye-chalcogenide efunyenweyo yayiyi-400-500 nm, kwaye yadityaniswa kuthotho kunye ne-heterojunction cell ephantsi ukuze kuphuculwe ukuhambelana kwangoku. Izaleko zothutho lwe-electron kwifilimu ye-chalcogenide yi-LiF kunye ne-C60, efunyenwe ngokulandelelana ngokubekwa komphunga oshushu, ilandelwa ngumaleko we-athomu wokubekwa kwe-buffer layer, i-Sn02, kunye ne-magnetron sputtering ye-TCO njenge-electrode esobala yangaphambili. Ukuthembeka kwale seli egciniweyo ingcono kune-chalcogenide ye-cell-layer cell, kodwa ukuzinza kwefilimu ye-chalcogenide phantsi kweempembelelo zokusingqongileyo zomphunga wamanzi, ukukhanya, kunye nobushushu kusafuna ukuphuculwa.
