Formation of high-quality poly-Si films by flash lamp annealing and their application to high-efficiency solar cells
We investigate on formation of high-quality poly-Si on glass substrates by flash lamp annealing, with millisecond duration, of Cat-CVD a-Si films and fabrication of solar cells using the poly-Si films.
Application of Cat-CVD to the fabrication process of c-Si solar cells
Cat-CVD (catalytic chemical vapor deposition), in which gas molecules are decomposed on heated catalyzing wire by catarytic reaction, can deposit high-quality passivation films to reduce the recombination of photo-generated carriers on crystalline Si surface. We develop high-quality Cat-CVD passivation films for crystalline Si solar cells. We also investigate a novel doping method using a Cat-CVD system.
Potential-induced degradation for n-type crystalline silicon photovoltaic modules
The performance degradation of photovoltaic modules originating from a large voltage between an Al frame and cells (potential-induced degradation: PID) has been a significant problem in large-scale PV power plants. We investigate the mechanism of PID and its suppression particularly for n-type c-Si PV modules, which have higher performances than p-type ones and are thus expected to be widely utilized in the future.
