摘要：
单线态裂变是多激子产生的一种形式，发生于有机发色团中：一个高能单线态激子分离为两个低能三线态激子，每个三线态激子的能量约为单线态能量的一半。由于该过程是自旋允许的，它可以在不到数皮秒的超快时间尺度上进行，胜过大多数其他损耗机制，并达到接近200%的定量产率。由于这种高量子效率，单线态裂变过程有望成为减少光伏电池中热化损耗的一种手段。这将有可能使效率提升超过单结电池的热力学极限。在过去十年中，将这一过程纳入太阳能光伏电池的努力涵盖了广泛的器件结构。在本综述中，我们对这些尝试进行比较和分类，以评估该领域的现状，并确定未来研究与开发最有前景的途径。
英文摘要：
Singlet fission is a form of multiple exciton generation which occurs in organic chromophores when a high energy singlet exciton separates into two lower energy triplet excitons, each with approximately half the singlet energy. Since this process is spin-allowed it can proceed on an ultrafast timescale of less than several picoseconds, outcompeting most other loss mechanisms and reaching quantitative yields approaching 200%. Due to this high quantum efficiency, the singlet fission process shows promise as a means of reducing thermalisation losses in photovoltaic cells. This would potentially allow for efficiency improvements beyond the thermodynamic limit in a single junction cell. Efforts to incorporate this process into solar photovoltaic cells have spanned a wide range of device structures over the past decade. In this review we compare and categorise these attempts in order to assess the state of the field and identify the most promising avenues of future research and development.
