Ikoreshwa rya tekinoroji muri Calcitonite Solar selile

Muri 2009, igihe calcite yoroheje-firime yatangiraga kugaragara imikorere yo guhindura yari 3.8% gusa, kandi ikiyongera vuba, Unit 2018, laboratoire yarenze 23%. Inzira fatizo ya molekuline yibanze ya chalcogenide ni ABX3, naho A umwanya mubisanzwe ni ion yicyuma, nka Cs + cyangwa Rb +, cyangwa itsinda ryimikorere kama. Nka (CH3NH3;), [CH (NH2) 2] +; Umwanya B mubisanzwe ni cations zingana, nka Pb2 + na Sn2 + ion; Umwanya X mubisanzwe ni halogen anion, nka Br-, I-, Cl-. Muguhindura ibice bigize ibice, umurongo wabujijwe kwaguka wa chalcogenide urashobora guhinduka hagati ya 1.2 na 3.1 eV. Ihinduramiterere ryinshi rya fotovoltaque ya selile ya chalcogenide kumurambararo mugufi, hejuru ya selile zifite imikorere idasanzwe yo guhinduranya kumurongo muremure, nka selile ya silicon ya heterogeneous, ishobora kubona uburyo bwo guhindura amafoto arenga 30%, bikarenga imipaka yuburyo bwiza bwo guhindura imikorere ya selile ya silicon ya 29.4%. 2020, iyi bateri yegeranye imaze kugera kuri 29.15% muri Laboratoire ya Berlin ya Heimholtz, mu Budage, kandi selile ya chalcogenide-crystalline silicon Stacked selile ifatwa nkimwe mu buhanga bukomeye bwa batiri bwibisekuruza bizaza.

Igice cya firime ya chalcogenide cyatahuwe nuburyo bubiri: icya mbere, ama pbl2 ya Pbl2, na CsBr yashyizwe hejuru yutugingo ngengabuzima twa heterojunction hamwe nuduce twinshi hamwe no guhumeka, hanyuma igapfundikirwa igisubizo cya organohalide (FAI, FABr) ukoresheje spin-coating. Umuti wa halide wibanze winjira mu byobo bya firime itabitswe na pompe ya organique hanyuma ikabyitwaramo ikabika kuri dogere selisiyusi 150 kugirango ikore firime ya chalcogenide. Ubunini bwa firime ya chalcogenide yabonetse rero ni 400-500 nm, kandi yahujwe murukurikirane na selile ya heterojunction kugirango ihuze neza. Ibikoresho bya transport bya elegitoronike kuri firime ya chalcogenide ni LiF na C60, byabonetse bikurikiranye no guhumeka imyuka yumuriro, hanyuma bigakurikirwa na atomic layer ya buffer, Sn02, na magnetron bisuka TCO nka electrode yimbere. Ubwizerwe bwiyi selile yegeranye nibyiza kuruta ubw'akagari ka chalcogenide kamwe kamwe, ariko ituze rya firime ya chalcogenide munsi y’ibidukikije byangiza imyuka y’amazi, urumuri, nubushyuhe biracyakenewe kunozwa.
