We report a general approach involving the heating of glass substrates for fabricating spray-coated organic photovoltaic cells. We heated a substrate was heated to temperatures of 50, 100, and 150 °C during the spray-coating process and observed different morphology of the active layer. It was found that the morphology influenced the performance of the organic solar cell. The solar cell subjected to spray coating at a substrate temperature of 150 °C showed a power conversion efficiency (PCE) of ${\sim}3.84$%, an open voltage of ${\sim}0.61$ V, and a short current density of ${\sim}20$ mA/cm2. After optimizing post annealing, we obtained the PCE up to 4.3%.
