High-efficiency ultrathin crystalline silicon solar cells
Abstract/Contents
- Abstract
- The climate change associated with burning fossil fuels as dominant energy resource has been a significant concern. Solar photovoltaics (PV) is the dominant type of renewable and eco-friendly energy resource to alleviate this problem. Crystalline silicon (c-Si) PV has been the dominant type of solar cell with more than 90% of the global PV market at the end of 2017, because of its low-cost, good stability and well-developed processing technology. To continue reducing the price of solar modules, ultrathin c-Si solar cells have been investigated: they are a feasible pathway to continue "price scaling" by effectively reducing the c-Si material consumption. However, the performance of ultrathin c-Si cells is constrained by two physical limitations: poor light absorption and contact recombination. To achieve the optimal efficiency from ultrathin c-Si cells, the cells must be designed to overcome these limitations. This dissertation provides comprehensive experimental strategies to overcome these two performance limitations of ultrathin c-Si solar cells. The main part of this dissertation concludes with the characterization of the "free-standing", ultrathin c-Si cell integrated with carrier-selective contacts and light trapping structures. These cells show very consistent performance before and after being released from the substrate. These findings show the capability of ultrathin c-Si technology to not only reduce the material cost, but also maintain high efficiency.
