The huge energy demand is increasing due to global population growth and economic development results in fast depletion of traditional energy sources. Therefore we need an alternative energy source which not only satisfy our current energy needs but also have low environmental effect. Among the renewable energy sources solar energy would be best option because sun is the most abundant energy source. The dye-sensitized solar cell (DSSC) is an alternative to common silicon solar cells due to its advantages of easy fabrication, cost effective and high solar to electric conversion efficiencies. In DSSC technology, does not require clean room facility and highly pure materials. An attempt has been made through this article to report the development of key components transparent conducting substrate, photoanode, dye sensitizers, counter electrode and redox electrolyte in dye-sensitized solar cells. Additionally, DSSC operating principal and characterizations are also described in the review article.
