Dye-sensitized TiO2 solar cells, DSSC, are a promising alternative for the development of a new generation of photovoltaic devices. DSSC are a successful combination of materials, consisting of a transparent electrode coated with a dye-sensitized mesoporous film of nanocrystalline particles of TiO2, an electrolyte containing a suitable redox-couple and a Pt coated counter-electrode. In general, Ru bipyridyl complexes are used as the dye sensitizers. The light-to-energy conversion performance of the cell depends on the relative energy levels of the semiconductor and dye and on the kinetics of the electron-transfer processes at the sensitized semiconductor | electrolyte interface. The rate of these processes depends on the properties of its components. This contribution presents a discussion on the influence of each of the materials which constitute the DSSC of the overall process for energy conversion. An overview of the results obtained for solid-state dye-sensitized TiO2 solar cells assembled with polymer electrolytes is also presented.

• Recent advances in dye sensitized solar cells (2014, background): “This phenomenon, the resulting current of which is known as the dark current, diminishes the efficiency of DSSCs, and it can be minimized by employing structural changes, use of insulating layers, or surface treatment of TiO 2 [28].”
• Status and outlook of sensitizers/dyes used in dye sensitized solar cells (DSSC): a review (2016, background): “It helps in absorbing the visible light, pumping an electron into the conduction band of TiO2 layer, accepting an electron from the redox couple, and then repeating the cycle [27,28].”
