Ushbu ishda galogenidli perovskit yarimo‘tkazgichlar asosidagi quyosh elementlarining fizik asoslari, so‘nggi yillardagi yutuqlari va amaliy qo‘llanilishini cheklovchi omillar tahlil qilingan. Perovskit materiallarning yuqori yorug‘lik yutish koeffitsiyenti, taqiqlangan zona kengligining kimyoviy tarkib orqali boshqarilishi hamda zaryad tashuvchilarning katta diffuziya uzunligi ularning samaradorligini qisqa vaqt ichida 3,8 % dan 26 % dan yuqori qiymatgacha oshirish imkonini berdi. Perovskit/kremniy tandem tuzilmalari Shokli–Kvaysser chegarasidan oshib, 34 % dan yuqori samaradorlikka erishdi. Shu bilan birga, namlik, harorat, yorug‘lik ta’sirida fazaviy beqarorlik va ion migratsiyasi texnologiyani sanoat miqyosida joriy etishdagi asosiy to‘siq bo‘lib qolmoqda. Maqolada ushbu muammolarning fizik tabiati va ularni yechishning zamonaviy yondashuvlari ko‘rib chiqilgan.
