Highly sensitive spectroscopic study of interfacial disorder and its correlation with the solvent additive and the molecular structure of the donor in bulk heterojunction organic solar cells.
Dithienopyrrole-based small molecular materials were developed achieving PCEs up to 5.3% in bulk-heterojunction organic solar cells by the tuning of the alkyl substitution pattern and use of a solvent additive.
This article presents the results of research output voltage characteristics of solar cells on an organic basis with the use of P3HT: PCBM system. There were produced organic solar cells in a coating in air, current-voltage characteristics were measured. It was determined the characteristic influence of a substrate cleaning and annealing temperature of layers applied on fill factor and conversion efficiency.
