| Abstract: | Hybrid organic solar cells using nano-porous TiO2 infiltrated with MEH-PPV were made and characterized under standard AM 1.5 G solar illumination. Reverse biased annealing was performed on the fabricated cells as a post treatment and origin of the counter-diode was investigated by illuminating the cells through a UV-blocking filter. Treated devices deliver increased open circuit voltage and short circuit current density values, leading to significant increase in cell performances. |
