Fasahar Rufi a cikin Kwayoyin Rana na Calcitonite

A cikin 2009, lokacin da ƙwayoyin sel-fim na bakin ciki suka fara bayyana tasirin jujjuyawar shine kawai 3.8%, kuma ya karu da sauri, Unit 2018, ingancin dakin gwaje-gwaje ya wuce 23%. Tsarin kwayoyin halitta na fili na chalcogenide shine ABX3, kuma matsayin A yawanci ion karfe ne, kamar Cs + ko Rb+, ko ƙungiyar aiki na kwayoyin halitta. Kamar (CH3NH3;), [CH (NH2)2]+; Matsayin B yawanci cations ne, kamar Pb2+ da Sn2+ ions; Matsayin X yawanci halogen anions ne, kamar Br-, I-, Cl-. Ta hanyar canza abubuwan da ke cikin mahadi, haramtaccen bandwidth na mahaɗan chalcogenide yana daidaitawa tsakanin 1.2 da 3.1 eV. Canjin hoto mai inganci mai inganci na sel chalcogenide a ɗan gajeren zango, wanda aka ɗauka akan sel tare da ingantaccen aikin jujjuyawa a tsayin tsayin tsayi, kamar ƙwayoyin silicon crystalline daban-daban, na iya samun ingantaccen juzu'i na hotovoltaic fiye da 30%, yana karya ta iyakar ƙwararrun sel na siliki 2. 2020, wannan baturi mai tarin yawa ya riga ya sami ingantaccen juzu'i na 29.15% a cikin dakin gwaje-gwaje na Berlin na Heimholtz, Jamus, kuma ana ɗaukar chalcogenide-crystalline silicon Stacked cell a matsayin ɗayan manyan fasahar batir na ƙarni na gaba.

An gano fim ɗin fim ɗin chalcogenide ta hanyar matakai biyu: na farko, Pbl2 mai laushi, da fina-finai na CsBr an ajiye su a saman sel heterojunction tare da fashe mai laushi ta hanyar haɓakawa, sannan an rufe shi da maganin organohalide (FAI, FABr) ta hanyar sutura. Maganin halide na kwayoyin halitta yana shiga cikin ramukan fim din da aka ajiye a cikin tururi sannan ya amsa kuma ya yi crystallizes a digiri 150 na Celsius don samar da Layer na fim na chalcogenide. Girman fim ɗin chalcogenide don haka aka samu shine 400-500 nm, kuma an haɗa shi a cikin jerin tare da tantanin halitta heterojunction da ke ƙasa don haɓaka daidaitattun yanzu. Yaduddukan sufuri na lantarki akan fim ɗin chalcogenide sune LiF da C60, waɗanda aka samo su a jere ta hanyar jigon tururi na thermal, sannan saitin atomic Layer na wani buffer Layer, Sn02, da magnetron sputtering na TCO a matsayin fili na lantarki na gaba. Amincewar wannan tantanin halitta ya fi na chalcogenide guda ɗaya, amma kwanciyar hankali na fim din chalcogenide a ƙarƙashin tasirin muhalli na tururin ruwa, haske, da zafi har yanzu yana buƙatar ingantawa.
