| Outline of Final Research Achievements |
We have developed a high-efficiency solar cell created by synthesizing silicon nanoparticles with a quantum size effect and using printing technology. As a result of evaluating the performance of the photoelectric device using simulated indoor light as well as simulated solar light, a conversion efficiency of 10% was obtained with respect to the standard LED light source. We have shown the path to the implementation of low-cost and high-efficiency photovoltaic devices by consistently realizing mass synthesis of silicon nanoparticles, silicon ink production, development and evaluation of bulk heterostructures, and development of high-efficiency photoelectric conversion devices.
