In this study, we investigated the photovoltaic properties of newly synthesized low bandgap conjugated polymers, P1-TCP (thiophene-based conjugated polymer) and P2-SCP (selenophene-based conjugated polymer). These two conjugated low bandgap polymers were characterized by NMR and gel permeation chromatography. The physical properties of the polymers were studied by thermogravimetric analysis. Moreover, we also investigated the optical, electrochemical and morphological properties of both polymers by UV-vis spectroscopy, cyclic voltammetry and atomic-force microscopy (AFM), respectively. Later, we studied the photovoltaic properties of both low bandgap polymers blended with PC6161BM in different ratios with different thicknesses. In addition, post thermal annealing at different temperatures for both polymers was investigated, and the results show that P2-SCP exhibited stronger molecular orientation properties as compared to P1-TCP.
