In polymer solar cells, the active layers of the device must be located between two layers of conducting electrodes, one of which is transparent to incident light. Typically, for this purpose, a compound comprising indium tin oxide (ITO) coatings (a mixture of indium and tin oxides) applied to a glass or a flexible polymer substrate is used.
Experimental prototypes of organic solar cells were obtained on the basis of binary donor-acceptor layers and bulk heterojunctions, consisting of novel polyaniline derivatives and fullerene-contained polymers.
To further increase the efficiency of solar cells, it is necessary to develop donor polymers that absorb light in an even longer wavelength region than P3HT, that is, the absorption boundary should lie at wavelengths greater than 700 nm.
The photoactive layer of organic solar cells was created on the basis of the traditional composites: the acceptor component PCBM or PCBM and conjugated polymer Р3НТ or poly [ [9- (1-octylnonyl)-9H-carbazole-2,7-diyl]-2,5-thiophenediyl-2,1,3-benzothiadiazole-4,7-diyl-2,5-thiophenediyl] (PCDTBT).
Thus, the poly-2- (1-methyl-2-buten-1-yl)aniline/methanofullerene heterojunction, which is composed of newly synthesized compounds, is optimal for manufacturing a laboratory sample of a solar energy photoconverter. 5. Organic solar cells based on thin polymer films
