| Outline of Final Research Achievements |
Silicon (Si) nanoparticles-based solar cells have been attracting significant attention because of the possession of greater advantages such as low production cost of the solar cells. In this research project, we develop hybrid solar cells that combine impurity (i.e., phosphorus (P) or boron (B))-doped Si nanostructures with conducting organic polymers so as to reduce the production cost and improve the power conversion efficiency (PCE). We have succeed in establishing the impurity-doping, surface-passivation and size-control techniques of Si nanostructures, and also facile preparation technique of impurity-doped Si nanostructures-based solar cells. Additionally, the hybrid solar cells combining the P-doped Si nanostructures with the polymers attained a higher PCE compared to the hybrid solar cells combining the B-doped Si nanostructures with the polymers. From this result, we constructed optimal photoelectric conversion layer in hybrid solar cells, which can improve the PCE.
