The main goal of this paper was to show that organic layers prepared for organic solar cells construction can be partially characterized by IR thermographic camera to detect dysfunctionalities of the active layer. Moreover, we used IR thermographic camera to check thermal and electrical behaviour of created simple solar cells to reduce time and cost in global production of solar cells. As model system organic compounds such as PTB7 polymer and small molecule PC71BM as commercial components and newly synthesized imine PV-BLJ-SC11 there were used, to construct simple devices.

The Relationship

In this review, small-molecule donors for application in organic solar cells reported in the last three years are highlighted. Especially, the effect of donor molecular structure on power conversion efficiency of organic solar cells is reported in detail. Furthermore, the mechanism is proposed and discussed for explaining the relationship between structure and power conversion efficiency. These results and discussions draw some rules for rational donor molecular design, which is very important for further improving the power conversion efficiency of organic solar cells based on the small-molecule donor.
