Ka 2009, ha lisele tsa filimi e tšesaane ea calcite li qala ho hlaha, katleho ea phetoho e ne e le 3.8% feela, 'me ea eketseha ka potlako haholo, Yuniti ea 2018, katleho ea laboratori e fetile 23%. Foromo ea motheo ea limolek'hule ea motsoako oa chalcogenide ke ABX3, 'me boemo ba A hangata ke ion ea tšepe, joalo ka Cs+ kapa Rb+, kapa sehlopha sa ts'ebetso ea organic. Joalo ka (CH3NH3;), [CH (NH2)2]+; Boemo ba B hangata ke li-cation tse arohaneng, joalo ka li-ion tsa Pb2+ le Sn2+; Boemo ba X hangata ke li-anion tsa halogen, joalo ka Br-, I-, Cl-. Ka ho fetola likarolo tsa metsoako, bandwidth e thibetsoeng ea metsoako ea chalcogenide e ka fetoloa pakeng tsa 1.2 le 3.1 eV. Phetoho e phahameng ea photovoltaic ea lisele tsa chalcogenide boleleleng ba maqhubu a makhutšoane, e behiloeng holim'a lisele tse nang le ts'ebetso e ikhethang ea phetoho boleleleng ba maqhubu a malelele, joalo ka lisele tsa silicon tse fapaneng tsa kristale, ka khopolo-taba li ka fumana ts'ebetso ea phetoho ea photovoltaic e fetang 30%, li feta moeling oa ts'ebetso ea phetoho ea khopolo-taba ea lisele tsa silicon tse kristale ea 29.4%. 2020, betri ena e kopantsoeng e se e fihletse ts'ebetso ea phetoho ea 29.15% Laboratoring ea Berlin ea Heimholtz, Jeremane, 'me silicon ea chalcogenide-crystalline Sele e kopantsoeng e nkoa e le e 'ngoe ea mahlale a maholo a betri a moloko o latelang.
Lera la filimi la chalcogenide le ile la bonoa ka mokhoa oa mehato e 'meli: ea pele, lifilimi tsa Pbl2, le CsBr tse nang le masoba li ile tsa beoa holim'a lisele tsa heterojunction tse nang le libaka tse boreleli ka ho kopana le mouoane, ebe li koaheloa ka tharollo ea organohalide (FAI, FABr) ka ho koahela ka spin. Tharollo ea halide ea organic e kenella ka har'a masoba a filimi e sa tloaelehang e bolokiloeng ka mouoane ebe e arabela le ho kristaleha likhatong tse 150 tsa Celsius ho theha lera la filimi la chalcogenide. Botenya ba filimi ea chalcogenide e fumanoeng ka tsela eo e ne e le 400-500 nm, 'me e ile ea hokahanngoa ka tatellano le sele ea heterojunction e ka tlase ho ntlafatsa ho lumellana ha hona joale. Mealo ea lipalangoang tsa elektrone filiming ea chalcogenide ke LiF le C60, e fumanoeng ka tatellano ka ho kenngoa ha mouoane oa mocheso, e lateloa ke ho kenngoa ha athomo ea lera la buffer, Sn02, le magnetron sputtering ea TCO e le electrode e ka pele e bonaletsang. Botšepehi ba sele ena e kopaneng bo betere ho feta ba sele ea chalcogenide e nang le lera le le leng, empa botsitso ba filimi ea chalcogenide tlas'a tšusumetso ea tikoloho ea mouoane oa metsi, leseli le mocheso bo ntse bo hloka ho ntlafatsoa.
