A small organic moleculeCSORG5developed as non fullerene acceptor for BHJ solar cells. The device based on P3HT : CSORG5(1 : 1) spin coated from DIO/THF showed high PCE 2.80% compared to spin coated from THF. The PCE has been further increased to 4.16%, when the TiO2film was inserted between the active layer and Al electrode.
