Dye-sensitized solar cells (DSSCs) have been deemed as promising alternatives to silicon solar cells for the conversion of clean sunlight energy into electricity. A major limitation to their conversion efficiency is their inability to utilize light in the infrared (IR) spectral range, which constitutes almost half the energy of the sun's radiation. This fact has elicited motivations and endeavors to extend the response wavelength of DSSCs to the IR range. Photon upconversion through rare-earth ions constitutes one of the most promising approaches toward the goal of converting near-IR (NIR) or IR light into visible or ultraviolet light, where DSSCs typically have high sensitivity. In the present review, we summarize recent progress based on the utilization of various upconversion materials and device structures to improve the performance of dye-sensitized solar cells.
染料敏化太阳能电池 (DSSC) 被认为是将清洁的太阳能转化为电能的硅太阳能电池的有前途的替代品。其转换效率的一个主要限制是它们无法利用红外 (IR) 光谱范围内的光，而红外光构成了太阳辐射能量的近一半。这一事实激发了人们的动机和努力，以将 DSSC 的响应波长扩展到 IR 范围。通过稀土离子进行光子上转换是将近红外 (NIR) 或 IR 光转换为 DSSC 通常具有高灵敏度的可见光或紫外光的最有前途的方法之一。在本综述中，我们总结了基于利用各种上转换材料和器件结构来提高染料敏化太阳能电池性能的最新进展。
