Sannadkii 2009, markii unugyada khafiifka ah ee calcite-ka ah ay bilaabeen inay soo baxaan waxtarka beddelka wuxuu ahaa 3.8% oo keliya, oo si dhakhso ah u kordhay, Cutubka 2018, waxtarka shaybaarku wuxuu dhaafey 23%. Qaaciddada molecular ee aasaasiga ah ee isku dhafka chalcogenide waa ABX3, booska A badanaa waa ion bir ah, sida Cs + ama Rb+, ama koox shaqeynaya organic. Sida (CH3NH3;), [CH (NH2)2]+; Booska B inta badan waa cations kala duwan, sida Pb2+ iyo Sn2+ ions; Booska X inta badan waa anions halogen, sida Br-, I-, Cl-. Beddelidda qaybaha xeryahooda, xadiga mamnuuca ah ee xeryahooda chalcogenide waa la hagaajin karaa inta u dhaxaysa 1.2 iyo 3.1 eV. Beddelka waxtarka sare leh ee sawir-qaadista ee unugyada chalcogenide ee hirarka gaaban, oo lagu dul saaray unugyada leh waxqabadka beddelka ee cajiibka ah ee dhererka dhaadheer, sida unugyada silikon crystalline heterogeneous, waxay aragti ahaan heli karaan hufnaanta beddelka sawir-voltaic ee in ka badan 30%, jabinta xadka aragtida unugyada kristal effili4. 2020, baytarigan isku xidhan waxa uu horeba u gaadhay wax ku oolnimada beddelka 29.15% ee Shaybaadhka Berlin ee Heimholtz, Jarmalka, iyo unugga chalcogenide-crystalline silicon Stacked cell ayaa loo arkaa mid ka mid ah tignoolajiyada batteriga ugu weyn ee jiilka soo socda.
Lakabka filimka chalcogenide waxaa lagu xaqiiqsaday hab laba-tallaabo ah: marka hore, filimada Pbl2, iyo filimada CsBr ayaa lagu dhejiyay dusha sare ee unugyada heterojunction oo leh sagxadaha qallafsan ee wadajirka ah, ka dibna lagu daboolay xal organohalide (FAI, FABr) by lafdhabarta. Xalka halide-ka dabiiciga ah wuxuu dhex galayaa daloollada filimka aan noolaha lahayn ee uumiga ku kaydsan yahay ka dibna wuxuu ka falceliyaa oo uu kraysaleeyaa 150 darajo Celsius si uu u sameeyo lakabka filimka chalcogenide. Dhumucda filimka chalcogenide ee sidaas la helay waxay ahayd 400-500 nm, waxaana si taxane ah loogu xidhay unugga heterojunction ee hoose si loo wanaajiyo isbarbardhigga hadda. Lakabyada gaadiidka elektaroonigga ah ee filimka chalcogenide waa LiF iyo C60, oo si isdaba joog ah loo helay kaydinta uumiga kulaylka, oo ay ku xigto dhigista lakabka atomiga ee lakabka buffer, Sn02, iyo magnetron sputtering TCO sida korantada hore ee hufan. Kalsoonida unugyadan la isku dhejiyay ayaa ka fiican kan chalcogenide hal lakab, laakiin xasiloonida filimka chalcogenide ee hoos yimaada saamaynta deegaanka ee uumiga biyaha, iftiinka, iyo kulaylka ayaa weli u baahan in la hagaajiyo.
