Abstract :
Summary form only given. We have studied the performance of bulk hetorojunction solar cell after the thermal treatment of active layer, where donor and acceptor molecules have been poly(3-hexylthiophene) (P3HT) and Buckminster fullerene (PCBM) respectively. The devices under study were fabricated in bulk hetorojunction configuration ITO/PEDOT:PSS/P3HT:PCBM/Al. Devices have been fabricated in different P3HT:PCBM ratio. For this PEDOT:PSS was spin coated on cleaned ITO substrates and cured at 100 degC for 30 min. Subsequently P3HT:PCBM was spin coated and thermal treated at different temperatures. Finally Al electrode was thermally evaporated in vacuum through the shadow mask on the substrates. The films were deposited in inert conditions.
