“…A solid-state device based on CuI was first demonstrated by Tennakone et al [97], and a conversion efficiency as high as 4.7% has been reported [98]. Although CuI is a very promising material, the cells are generally unstable, which is attributed to a stoichiometric excess of iodine molecules adsorbed at the CuI surface, acting as hole-trapping sites [99]. An alternative is incorporated CuSCN as the hole-transporter, which improved stabilities.…”

Dye-sensitized solar cells (DSSCs) are recognized as one of the world's leading innovation in nanosciences and photovoltaic technology. In contrast to the conventional silicon-based solar cells the demand on purity of materials for DSSC is lower and forecasted manufacturing costs are approximately halved which make the DSSCs attractive alternative. Nowadays the conversion efficiency of DSSCs exceeds 10% which makes it competitive with other thin film solar cells. In this chapter the structure and the fundamental operation of the DSSC are presented. Afterwards the properties and requirements for each individual component used in a DSSC are given. In addition advanced hybrid DSSC systems also are presented. In overall, the emphasis of this chapter is given to the involvement of sol-gel chemistry in the preparation of the individual DSSCs components, primarily of TiO 2 layers and electrolytes.

This Progress Report highlights recent developments in dye‐sensitized solar cells composed of both liquid electrolytes and solid‐state hole transport materials. The authors discuss and review the present understanding of and recent developments in the operational processes, such as charge generation, transport, recombination, and charge collection. Also, the merits and challenges of alternative device approaches are discussed, including extremely thin absorber cells, devices containing inorganic p‐type hole‐transporters and non‐TiO2 mesoporous metal‐oxide electrodes employed in dye‐sensitized solar cells.

A convenient liquid-phase route was proposed to synthesize well-dispersed CuI nanoparticles from Cu+–DMF solution precursor, which was prepared by dissolving bulk CuI in DMF. When water was gradually added, nanoscaled CuI was produced through the decomposition of the complex formed in this solution. A passivation layer of Cu+–DMF adsorbed on the particle surface was suggested to be responsible for the nanoparticle formation.
