Maqolada chuqur aralashma satxlarning p-CdTe/n-CdS va p-CdTe/n-CdSe plyonka geterostrukturalarining fotoelektrik parametrlariga ta'siri o'rganiladi. Cho'kish jarayonida chuqur satxlarni shakllantirish mexanizmlari va qatlamlarni keyingi termal ishlov berish ko'rib chiqiladi. Chuqur satxlarning mavjudligi zaryad tashuvchining rekombinatsiyasi jarayonlariga sezilarli ta'sir ko'rsatishi, ozchilik tashuvchilarning ishlash muddatini qisqartirishi va tuzilmalarning spektral sezgirligining o'zgarishiga olib kelishi aniqlandi. Asosiy fotoelektrik xarakteristikalar - fototok, fotovoltaj va kvant rentabelligining chuqur sathlarning zichligi va energiya holatiga bog'liqligi tahlili keltirilgan. Olingan natijalar p-CdTe/n-CdS va p-CdTe/n-CdSe geterostrukturalari asosida yuqori samarali fotoelektron qurilmalar va quyosh batareyalarini yaratish uchun texnologik parametrlarni optimallashtirish bo‘yicha tavsiyalar ishlab chiqish imkonini beradi. Aniqlanganki, CdTe tarkibidagi chuqur aralashmalar Ec=1,15 eV ga teng aktivlanish energiyalariga ega.
