Nanomaterials for photoelectrodes in dye sensitized solar cells-a Review

摘要

Dye-sensitized solar cells (DSSCs) are the representative of third generation photovoltaicdevices due to its low cost, easy fabrication, and relatively high energy conversion efficiency. Still, there is a lot of scope for the replacement of current DSSC materials due to their high cost, less abundance, and long-term stability. Thispaper summarizes the recent progress in DSSC technology for improving efficiency, focusing on the active layer in the photoanode,with a part of the DSSC consisting of dyes and a TiO2film layer. The application of these nanostructured photoanode materials and their impact on the device efficiency has been described in detail.
