海报摘要
- In this poster we reporte the results of a detailed comparative LEPR study of photovoltaics composits P3DDT:PC61BM slightly doped with several simplest acenes and others 2D molecules. Acenes are characterized by the most conjugate and planar structure. Therefore, the using of these small molecules as additives could be expected to more increase intermolecular π-π-interaction in the P3DDT:PC61BM composite, improve its ordering and energy-conversion properties. With this modification of the composite, we found an increase in the concentration and stability of both mobile charge carriers. Such an effect was interpreted in favor of trigger-like polymorphic α-β-transition in the composite stimulated by π⸺π interaction of 2D molecules. The data obtained allowed us to find the correlations interconnecting the main spectral resonant parameters of spin charge carriers with the structure, composition of the samples studied, as well as with the energy of the initiating light photons
