The conversion of solar energy is likely to play a key role as one of the technologies in the generation of mass energy. However, the current high cost of solar panels made from traditional inorganic semiconductors imposes a restriction on their mass usage. Alternative cheaper solar energy technologies are therefore under intensive study and in this context dye-sensitized solar cells have emerged as an important class of photovoltaic device to obtain robust, efficient and cheap devices that are suitable for practical use. Dyes play an important role in dye-sensitized solar cells. N3, N719 and Black dyes are the best known stable dyes having more than 10 % power conversion efficiency. The purpose of this project is to develop novel dye component for DSSC. N-heterocyclic carbene based ruthenium complex was designed in order to obtain high thermostability and high conversion efficiency than the known dyes.
