✦ Synopsis

Solid state dye-sensitized solar cells were fabricated using polydiacetylene as the hole transport material. The polydiacetylene was incorporated into the nanoporous TiO 2 film by solution casting of an amphiphilic diacetylene and subsequent in situ polymerization. Polydiacetylenes as prepared via solid state polymerization are crystalline, exhibiting high charge carrier mobility. Our preliminary experiments demonstrated a short-circuit current density of 3.73 mA/cm 2 and an overall power conversion efficiency of 0.62% under AM 1.5 illumination (100 mW/cm 2 ).

## Abstract The control of interfacial charge transfer is central to the design of photovoltaic devices. This charge transfer is strongly dependent upon the local chemical environment at each interface. In this paper we report a methodology for the fabrication of a novel nanostructured multicompone
