While hopes are high, heterogeneous photochemical systems seem not yet to have found major practical application. The photovoltaic cell or solar cell is the only system with important (although specialized) commercial use (see Ref. 343). 

Explain the photochemical principles of the dye-sensitised solar cell and understand the importance of various physicochemical parameters to the overall performance of such a cell.

In this review article, the functions of polymers and molecular assemblies for solar energy conversion will be described including photochemical conversion models, elemental processes for the conversion such as charge separation, electron transfer, and catalysis for water decomposition, as well as solar cells. 

Electron transfer of sensitizers m the photoexcited state is important for constructing photochemical conversion systems since energy conversion such as that shown in the scheme of Fig. 19.2 can be realized only by heterogeneous phase(s). Heterogeneous electron transfer is also important in the development of a dye-sensitized solar cell thal is attracting the attention of many researcners now. This is discussed in the next section.

This type of device has been contrasted489 with a series connection of a photovoltaic p-n junction solar cell and a water electrolyzer. Unlike the latter which is a majority carrier system (i.e., the n-side of the junction is the cathode and the p-side becomes the anode), in a photochemical diode, minority carriers (holes for the n-type and electrons for the p-type) are injected into the electrolyte. This distinction translates to certain advantages in terms of the overall energetics of the solar energy conversion system (see Ref. 489). 

For example, rhenium(I) complexes have been used as emitter materials in electroluminescent devices 17-20) and biological probes (11), as dye for dye-sensitized solar cells (21), as chromophores for photochemical electron or energy transfer studies (14,17,22), and as a redox photosensitizer (23).
