Fabrication of Si Quantum Dots/SiC Multilayers for All-Si Solar Cells
In this study,amorphous Si/SiC multilayers were fabricated in plasma enhanced chemical vapor deposition (PECVD) system.As-deposited films were subsequently annealed at 900℃ to form Si quantum dots (QDs)/SiC stacked structures.The microstructures and optical properties were studied.The cells containing Si QDs/SiC stacked structures were prepared.The photovoltaic properties were observed and a good spectral response in a wide spectral range (400nm-1000nm) can be achieved.It was also found that by reducing the SiC barrier thickness,the external quantum efficiency can be improved significantly due to the better carrier collections.
