V2O5 as an inexpensive counter electrode for dye sensitized solar cells
MATERIALS RESEARCH EXPRESS(2016)
摘要
In pursuit of an abundant, inexpensive and stable counter electrode as an alternative to platinum for dye-sensitized solar cells (DSSCs), we report a new, low-cost substitute material. Here for the first time, we demonstrate that V2O5 can be used as a counter electrode material in DSSCs. We note that the efficiency of DSSCs with commercial V2O5 and hydrothermal treated V2O5 are upto 1.2% and 1.6%, respectively. The results indicate that, with optimization, V2O5 can be a promising choice to replace platinum from a cost perspective. The innovation of new economical counter electrodes offers a potential way to cut down the industrial costs which is crucial for large-scale production and commercial applications of DSSCs.
