Abstract

. In this paper, we fabricated organic solar cells using spray-coating with substrate heated method. We heated substrate temperature to 50 °C, 100 °C, and 150 °C respectively, during spray-coating process and observed different morphologies of the active layer. The difference of morphologies affected the performance of the organic solar cell. One of these samples, substrate heated as 150 °C, showed an open voltage of 0.61 V, short current density of 20 mA/cm2 and power conversion efficiency of 3.84%.
