MAPbI3 VA MAPbICl2 ASOSIDAGI PEROVSKIT QUYOSH ELEMENTLARNING HARORATNI NAZORAT QILISH ORQALI FOTOVOLTAIK PARAMETRLARINI YAXSHILASH
##submission.downloads##
Perovskit quyosh element (PQE) larida termik qizdirish usuli va prekursorning tarkibi fotovoltaik parametrlarining yuqori
natijalarga erishish uchun, kristallanish jarayonini nazorat qilish hamda, perovskit faol qatlamlarning morfologiyasini
shakllantirishda muhim ro‘l o‘ynaydi. Ushbu ishda (CHNH 3 PbI 3 ) MAPbI 3 va MAPbICl 2 prekursorlaridan tayyorlangan
perovskit faol qatlamlarning qizdirish haroratining kristallanishiga ta’siri o‘rganildi. Bunda, yuqori qizdirish harorati perovskit
kristall strukturasining aglomeratsiya (tugunchalar) hosil bo‘lishiga olib keldi. Bu o‘z navbatida PQE larining fotovaltaik
parametlar pasayishiga olib keladi. MAPbICl 2 PQE larida qizdirish haroratining oshishi bilan faol qatlamda kristallanish hajmi
shakllanishining sezilarli darajada o‘zgarishi kuzatildi. Ammo, MAPbI 3 perovskit asosidagi quyosh elementalari morfologiyasi
va kristallanish hajmi qizdirish haroratining oshishi bilan MAPbICl 2 perovskit quyosh elementlariga qaraganda fotovaltaik
ko‘rsatkichlari oshdi, bu yutilish spektri va energiya o‘zgartirish samaradorligi (EO‘S) bilan ham tasdiqlangan.
