Developments in and Prospects for Photocathodic and Tandem Dye-sensitized Solar Cells

Publication date: Available online 30 June 2016 Source:Journal of Photochemistry and Photobiology C: Photochemistry Reviews Author(s): Andrew Nattestad, Ishanie Perera, Leone Spiccia Third generation photovoltaics are based on the concept of providing high conversion efficiencies with low device production costs. As such, second generation concepts, such as Dye-sensitized Solar Cells (DSCs), serve as a good starting point for the development of these new devices. Tandem DSC devices are one example of such a concept, and can be constructed using two photoactive electrodes (one photoanode and one photocathode) inside the one cavity, increasing the theoretical efficiency limit by around 50% as compared to the conventional design. As there has been substantial effort devoted to the development of n-type DSCs, the focus of researchers investigating tandem DSCs has been to create high performance p-type systems, which operate by an analogous, but inverted, mechanism to n-type DSCs.
