论文摘要
薄晶硅太阳能光伏具有巨大的潜力，可以通过材料节省来降低模块价格，并通过减少体积重组损失来提高效率。但是，随着模块温度在阳光下的上升，模块效率降低了。有效，廉价的冷却模块方法将加速大规模的市场采用薄晶硅光伏。为了有效冷却，我们利用了单晶薄硅膜的高灵活性来产生波浪状的太阳能电池。这些波浪细胞比常规平坦细胞具有更大的表面积，同时占据了相同的投影区域。我们在实验上证明，由于其较大的表面积引起的对流冷却，可以大大降低阳光下薄波浪状晶体太阳能电池的温度。通过有效去除热量来实现的大量效率增益指向高性能薄晶体硅光伏系统，与常规系统的配置截然不同。
Thin crystalline silicon solar photovoltaics holds great potential for reducing the module price by material saving and increasing the efficiency by reduced bulk recombination loss. However, the module efficiency decreases rather sensitively as the module temperature rises under sunlight. Effective, inexpensive approach to cooling modules would accelerate large-scale market adoption of thin crystalline silicon photovoltaics. For effective cooling, we exploit high flexibility of single-crystalline thin silicon films to create wavy solar cells. These wavy cells possess larger surface area than conventional flat cells, while occupying the same projected area. We experimentally demonstrate that the temperature of thin wavy crystalline silicon solar cells under the sunlight can be significantly reduced by increased convective cooling due to their large surface area. The substantial efficiency gain, achieved by the effective heat removal, points to high-performance thin crystalline silicon photovoltaic systems that are radically different in configuration from conventional systems.
