Abstract

Bulk heterojunction organic solar cells (OSCs) were fabricated by using the mist deposition method. The mist flow of two organic materials poly(3-hexylthiophene-2,5-diyl) (P3HT) and [6,6]-Phenyl C61 butyric Methyl Ester (PCBM) was generated using an ultrasonic oscillator and deposited on substrates as active layers of OSCs. Their thickness strictly depended on the substrate temperature. The current-voltage characteristics depended on the duration time of the mist deposition. The maximum power conversion efficiency (PCE) was about 1.61%.
