Special Issue Information

Dear Colleagues,

Organic solar cells (OSC) and dye-sensitized solar cells (DSSC) are very important emerging photovoltaics. The power conversion efficiency (PCE) of OSCs and DSSCs is a bottleneck for commercialization. The design and synthesis of novel molecules/materials for OSCs and DSSCs play a critical role in improving PCE, although dopant, addictive, electrolyte, morphology, electrode, device architectures also impact photovoltaic performance. Meanwhile, the thorough understanding of work principles both experimentally and theoretically, such as exciton dynamics in OSCs and electron injection dynamics in DSSCs, are fundamental for improving PCE with the aim of developing novel materials.

In order to promote the development of OSCs and DSSCs, this Special Issue is devoted to reporting the latest advances from chemistry, materials and physics points of study. Research works on all aspects of OSCs and DSSCs are welcome in this Special Issue, especially the novel active layer materials of OSCs and dye sensitizers for DSSCs, as well as theoretical studies.

Interface modification is an important way to get better performance from organic solar cells (OSCs). A natural biomolecular material methionine was successfully applied as the electron transport layer (ETL) to the inverted OSCs in this work. A series of optical, morphological, and electrical characterizations of thin films and devices were used to analyze the surface modification effects of methionine on zinc oxide (ZnO). The analysis results show that the surface modification of ZnO with methionine can cause significantly reduced surface defects for ZnO, optimized surface morphology of ZnO, improved compatibility between ETL and the active layer, better-matched energy levels between ETL and the acceptor, reduced interface resistance, reduced charge recombination, and enhanced charge transport and collection. The power conversion efficiency (PCE) of OSCs based on PM6:BTP-ec9 was improved to 15.34% from 14.25% by modifying ZnO with methionine. This work shows the great application potential of natural biomolecule methionine in OSCs. Full article
