In situ polymerization of amphiphilic diacetylene for hole transport in solid state dye-sensitized solar cells
2006
Abstract 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 ).
