Abstract
The effect of central donor core on the properties of A-π-D-π-A donors where D is a porphyrin macrocycle was investigated for the fabrication of the organic solar cells, along PC 71 BM as electron acceptor. A new molecule consisting of Ni-porphyrin central donor core ( VC9 ) showed deep HOMO energy level and OSCs based on optimized VC9 :PC 71 BM realized overall power conversion efficiency (PCE) of 10.66% (J SC = 15.48 mA/cm 2 , FF = 0.65) with high open circuit voltage of 1.06 V with very low energy loss of 0.49 eV whereas VC8 :PC 71 BM counterpart showed PCE of 9.69% with V OC of 0.89 V, J SC of 16.25 mA/cm 2 and FF of 0.67. Although the OSCs based on the Zn-Porphyrin analogous VC8 showed higher J SC in comparison to VC9 , originated from the broader absorption profile of VC8 , leading the more exciton generation, the higher value of PCE of VC9 is due to higher value of V OC and reduced energy loss.
