Ka 2009, ha lisele tse tšesaane tsa filimi ea calcite li qala ho hlaha, katleho ea phetoho e ne e le 3.8% feela, 'me e eketsehile ka potlako, Unit 2018, katleho ea laboratori e fetile 23%. Mokhoa oa motheo oa molek'hule oa motsoako oa chalcogenide ke ABX3, 'me boemo ba A hangata ke ion ea tšepe, e kang Cs + kapa Rb +, kapa sehlopha se sebetsang sa lintho tse phelang. Joalo ka (CH3NH3;), [CH (NH2)2]+; B boemo hangata ke divalent cations, tse kang Pb2+ le Sn2+ ions; X boemo hangata ke halogen anions, tse kang Br-, I-, Cl-. Ka ho fetola likarolo tsa metsoako, bandwidth e hanetsoeng ea metsoako ea chalcogenide e ka fetoha pakeng tsa 1.2 le 3.1 eV. Phetoho e phahameng ea matla a photovoltaic ea lisele tsa chalcogenide ka nako e khutšoanyane ea wavelengths, e behiloeng ka holim'a lisele tse nang le ts'ebetso e tsotehang ea ho fetoha ha nako e telele, joalo ka lisele tsa silicon tsa crystalline tse fapaneng, ka khopolo e ka fumana katleho ea ho fetola photovoltaic ho feta 30%, ho tlōla moeli oa silicon ea theory 29. Ka 2020, betri ena e pakiloeng e se e fihletse katleho ea phetoho ea 29.15% Berlin Laboratory ea Heimholtz, Jeremane, 'me sele ea chalcogenide-crystalline silicon Stacked cell e nkoa e le e' ngoe ea mahlale a maholo a betri a moloko o latelang.
Lera la filimi ea chalcogenide le ile la lemohuoa ka mokhoa oa mehato e 'meli: pele, lifilimi tsa Pbl2, le CsBr tse porous li ile tsa behoa holim'a lisele tsa heterojunction tse nang le libaka tse fokolang ka ho fetoha mouoane, ebe li koaheloa ka tharollo ea organohalide (FAI, FABr) ka ho pota-pota. Tharollo ea organic halide e kenella ka har'a masoba a filimi e kentsoeng ke mouoane, ebe e arabela le ho phatsima ka likhato tse 150 tsa Celsius ho etsa lera la filimi ea chalcogenide. Botenya ba filimi ea chalcogenide e fumanoeng e ne e le 400-500 nm, 'me e ne e hokahane ka letoto la sele ea heterojunction e ka tlase ho ntlafatsa papali ea hajoale. Likarolo tsa lipalangoang tsa elektrone filiming ea chalcogenide ke LiF le C60, tse fumanoeng ka tatellano ka ho beoa ha mouoane oa mocheso, ho lateloa ke deposition ea atomic layer ea buffer layer, Sn02, le magnetron sputtering ea TCO e le electrode e bonaletsang e ka pele. Ho tšepahala ha sele ena e nang le stacked ho molemo ho feta ea chalcogenide single-layer cell, empa botsitso ba filimi ea chalcogenide tlas'a tšusumetso ea tikoloho ea mouoane oa metsi, leseli le mocheso o ntse o hloka ho ntlafatsoa.
