Quantum dot-sensitized solar cells using Si nanoparticles

Abstract

We have synthesized size-controlled Si nanoparticles using multi-hollow discharge plasma CVD and have assembled Si quantum dot-sensitized solar cells which are candidates for multiple exciton generation solar cells of the third generation photovoltaics. We have demonstrated extraction of carriers from Si nanoparticles to an external circuit using the Si quantum dot-sensitized solar cells.
