ELECTROSYNTHESIS OF QUANTUM DOT-SENSITIZED SOLID-STATE SOLAR CELLS

摘要

Finding alternative earth abundant solar cell materials beyond Si has been at the leading edge of research for many years. Hybrid materials based on conducting polymers (CPs) and inorganic semiconductors (SCs) undoubtedly constitute one of the most promising classes of such new materials. In this vein CPs can be employed as solid-state hole-transporter materials in dye-sensitized solar cells (DSSCs) using either molecular dyes, or quantum dots (ODs) as sensitizer. By replacing the homogenous redox couple (I/I3~-) by a solid-state hole-conductor, it is possible to avoid use of the liquid electrolyte, and the consequent drawbacks of conventional DSSCs, such as leakage, low thermal stability, corrosion of the counter electrode.
