Ikoranabuhanga ryo gusiga irangi mu turemangingo tw'izuba twa Calcitonite

Mu 2009, ubwo uturemangingo twa calcite twatangiraga kugaragara, ubushobozi bwo guhindura ibintu bwari 3.8% gusa, kandi bwiyongereye vuba cyane, muri Unit 2018, ubushobozi bwo muri laboratwari bwarenze 23%. Formula y'ibanze ya molekyuli y'ikintu cya chalcogenide ni ABX3, naho umwanya wa A ubusanzwe ni iyoni y'icyuma, nka Cs+ cyangwa Rb+, cyangwa itsinda ry'imikorere ya organic. Nka (CH3NH3;), [CH (NH2)2]+; umwanya wa B ubusanzwe ni cation zivanze, nka Pb2+ na Sn2+ iyoni; umwanya wa X ubusanzwe ni anioni za halogen, nka Br-, I-, Cl-. Mu guhindura ibice by'ibice, bandwidth ibujijwe y'ibice bya chalcogenide ihinduka hagati ya 1.2 na 3.1 eV. Guhinduranya uturemangingo twa chalcogenide mu buryo bugezweho ku burebure bugufi, bishyirwa ku turemangingo dufite imikorere myiza yo guhinduranya uturemangingo ku burebure bunini, nk'uturemangingo twa silicon dutandukanye, mu buryo bw'imitekerereze dushobora kubona ubushobozi bwo guhinduranya uturemangingo bwa fotovoltaic burenze 30%, bikanyura mu rugero ntarengwa rwo guhinduranya uturemangingo twa silicon dusanzwe ku kigero cya 29.4%. 2020, iyi bateri yashyizwe ku rwego rumwe yamaze kugera ku bushobozi bwo guhinduranya uturemangingo bwa 29.15% muri Laboratwari ya Berlin ya Heimholtz, mu Budage, kandi silicon ya chalcogenide-crystalline ifatwa nk'imwe mu ikoranabuhanga rikomeye rya bateri mu gisekuru gitaha.

Urusobe rwa filime ya chalcogenide rwakozwe mu buryo bw'intambwe ebyiri: ubwa mbere, filime za Pbl2, na CsBr zifite imyenge zashyizwe ku buso bw'uturemangingo twa heterojunction hamwe n'ubuso bworoshye binyuze mu guhumeka, hanyuma zigatwikirwa n'umuti wa organohalide (FAI, FABr) binyuze mu gutwikira. Umuti wa halide organic winjira mu mwenge wa filime inorganic yashyizwemo umwuka hanyuma ugahinduka umunyu ku bushyuhe bwa dogere selisiyusi 150 kugira ngo ukore urwego rwa filime ya chalcogenide. Ubunini bwa filime ya chalcogenide yabonetse bwari 400-500 nm, kandi yahujwe mu buryo bukurikiranye n'akagari ka heterojunction gashingiyeho kugira ngo habeho guhuza neza umuriro. Uduce twa electron transporting kuri filime ya chalcogenide ni LiF na C60, twabonetse mu buryo bukurikiranye binyuze mu gushyira umwuka ushyushye, hagakurikiraho gushyira urwego rwa atome rw'urwego rwa buffer, Sn02, na magnetron sputtering ya TCO nk'electrode ibonerana imbere. Ubuziranenge bw'iyi selile igizwe n'ibice bibiri ni bwiza kurusha ubw'iseli ifite urwego rumwe rwa chalcogenide, ariko uburyo filime ya chalcogenide ihagaze neza bitewe n'ingaruka z'umwuka w'amazi, urumuri n'ubushyuhe biracyakeneye kunozwa.
