| Abstract |
| Dye sensitized solar cells (DSSCs), the third generation solar cell devices have been
designed to produce large-scale, inexpensive, environmentally benign solar power
devices having promising efficiency and lifetime. Albeit, perfect commercialization
of the devices has not been possible worldwide so far, research in this area is
immensely growing with promising future. Basic principles of DSSCs along with
essential characteristics of working electrode, photoanode and other major
components, namely photosensitizers, electrolytes and counter electrodes, which
are essential to fabricate an efficient device, are concisely highlighted in this review.
In addition, successive propagation of research based on the semiconducting oxides
as photoanode for the DSSC device starting from binary to ternary oxides, the
perspectives, selection strategies and the status with respect to performance has
also been highlighted. In an effort to introduce newer oxides as appropriate alternatives
to the pioneer TiO2, ZnO-SnO2 based ternary oxide Zn2SnO4 has become successful
and even better than its well-studied binary counterparts ZnO and SnO2 in a short
time. Taking into account the scattered reports available, the structural,
microstructural, opto-electronic and physico-chemical properties together with the
performance of the newly projected ternary oxide Zn2SnO4 are discussed in this short
review with a prospect of its potential as an alternative photoanode in DSSCs.
