Dye Sensitized

We demonstrate the use of small molecules to improve the performance of quasi-solid-state DSSC, the efficiency can reach 8.0% or 9.2% when a phenothiazine-based molecule is co-sensitized with black dye or a porphyrin-based dye.

The Relationship

This review attempts to summarize recent advances with respect to solution-processable molecular semiconductors having 2,1,3-benzothiadiazole or its fluorine substituted derivatives as electron-acceptor units published in the last few years. The relationship between the structure, optoelectronic properties, and photovoltaic performance of these molecular semiconductors is discussed.
