Kirish. Kuchli quyosh nurlanishi ta’sirida fotoelektr modullarining ishchi haroratining ortishi ularning elektr samaradorligini pasaytiradi hamda konstruksion materiallarning degradatsiya jarayonlarini tezlashtiradi. Issiq va quruq iqlim sharoitlarida qo‘shimcha energiya sarfini talab qilmaydigan passiv sovitish usullaridan foydalanish alohida ahamiyat kasb etadi.
Metodlar va materiallar. Mazkur ishda fotoelektr modulning orqa qismiga joylashtirilgan nam to‘qimachilik qatlami yordamida amalga oshiriladigan passiv bug‘latib sovitishning bir o‘lchamli statsionar matematik modeli ishlab chiqildi. Model fotoelektr modulning ko‘p qatlamli tuzilmasida issiqlik o‘tkazuvchanligi, bug‘lanish natijasidagi massa almashinuvi hamda nam havoning psixrometrik parametrlarini kompleks ravishda hisobga olishga asoslangan. Hisoblashlarda havo harorati, nisbiy namlik, namlik miqdori, barometrik bosim, havo oqimi tezligi hamda fotoelektrik energiya konversiyasi foydali ish koeffitsientining haroratga bog‘liqligi e’tiborga olindi.
Natijalar. Toshkent shahri iqlim sharoitlari uchun, havo harorati 40 °C va nisbiy namlik 20 % bo‘lganda, nam termometr harorati taxminan 24 °C ekanligi aniqlandi. Issiqlik o‘tkazuvchanlik tenglamalari asosida fotoelektr modulning kremniy qatlamidagi harorat taxminan 26 °C gacha pasayishi ko‘rsatildi. Natijada modulning haqiqiy foydali ish koeffitsienti 13,6 % ni tashkil etib, bu uning 14 % ga teng loyihaviy samaradorligiga yaqin qiymat ekanligi aniqlandi.
Xulosa. Olingan natijalar nam kapillyar-g‘ovakli to‘qimachilik qatlamidan foydalanish fotoelektr modullarni passiv bug‘latib sovitishning samarali usuli ekanligini ko‘rsatadi. Taklif etilgan usul qo‘shimcha energiya sarfisiz fotoelektrik energiya konversiyasidagi harorat tufayli yuzaga keladigan yo‘qotishlarni kamaytiradi hamda issiq va quruq iqlim sharoitlarida ishlovchi quyosh energetikasi tizimlari uchun istiqbolli yechim hisoblanadi.
