AI 中文摘要
单线态裂变（SF）材料能将高能光子转化为多个电荷载流子，为超越单结硅太阳能电池的效率极限提供了一条途径，且无需多结叠层设计的许多复杂性。在2025年首次演示了SF增强型硅太阳能电池之后，有必要理解如何将SF材料有效集成到高效率的工业硅器件中，并将其从概念验证转化为可制造的技术。通过耦合光学和电学模拟，我们评估了几种与SF材料结合的工业相关硅电池架构的效率潜力。交叉背接触（IBC）电池由于前表面无限制接触而具有最大的改进潜力，可实现超过33%的效率。然而，性能对前表面钝化质量高度敏感。适当的硅设计，特别是受控的表面掺杂和固定的界面电荷，可以减轻复合损失并放宽超薄激子传输层的钝化要求。
英文摘要
Singlet fission (SF) materials convert high-energy photons into multiple charge carriers, providing a route to exceed the efficiency limits of single-junction silicon solar cells without many of the complexities of multi-junction tandem designs. Following the first demonstration of an SF-enhanced silicon solar cell in 2025, there is a need to understand how SF materials can be effectively integrated into high-efficiency industrial silicon devices and translated from proof of concept to a manufacturable technology. Using coupled optical and electrical simulations, we assess the efficiency potential of several industrially relevant silicon cell architectures combined with SF materials. Interdigitated back-contact (IBC) cells offer the greatest potential for improvement due to unrestricted front-surface access and can achieve efficiencies exceeding 33%. However, performance is highly sensitive to front-surface passivation quality. Appropriate silicon design, particularly controlled surface doping and fixed interfacial charge, can mitigate recombination losses and relax passivation requirements for ultra-thin exciton-transfer layers.
