**7. Conclusion**

In sum, the work carried out showed the advisability of application of new organic materials for solar cell development. A combination of PANI with fullerene-containing polymer was used for formation of OSC on the basis of binary donor-acceptor systems. The poly-2-(1-methyl-2-buten-1-yl)aniline/methanofullerene bulk heterojunction, which is composed of newly synthesized compounds, is optimal for the manufacturing of solar cells.

The potential use of polymerizable acrylate and methacrylate fullerene derivatives to form a buffer electron-selective charge-transport layer in inverted-configuration solar cells was demonstrated. Achieved light conversion efficiency indicates prospects of further development in this research. Optimization of technological conditions of the thin films fabrication and correct selection of the organic materials composition will provide higher values of OSC efficiency.
