Abstract

An innovative solar-powered integrated system is proposed, combining a perovskite/homojunction tin sulfide (PSC/SnS) tandem solar cell, a solar selective absorber (SSA), and thermally regenerative electrochemical cycles/refrigerators (TRECs-TRERs) to maximize solar energy utilization. The PSC/SnS tandem solar cell (TSC), with well-matched bandgaps, efficiently converts a wider solar spectrum into electricity, while the SSA harnesses unabsorbed spectral components to drive cascaded TRECs-TRERs, providing additional cooling alongside power generation. Mathematical models incorporating irreversible physical and chemical processes are developed to elucidate the interaction between the TSC and the TRECs-TRERs system. Comprehensive analysis identifies key parameters influencing system performance, including operating temperature, defect density, doping density, work function of contact materials, regenerative efficiency, and internal resistance of TRECs-TRERs. The hybrid system maintains relatively stable efficiency under fluctuating operating temperatures, mitigating typical high-temperature degradation. Optimized parameters yield a maximum output power density of 368.1 W·m-² and a maximum energy efficiency of 36.81 %, demonstrating a 57.76 % enhancement over standalone PSC. This study provides valuable guidance the design of high-efficiency solar energy systems with integrated heat and power management.

串联太阳能电池与热再生电化学装置相结合的混合系统提高太阳能利用效率

提出了一种创新的太阳能集成系统，结合了钙钛矿/均结硫化锡（PSC/SnS）串联太阳能电池、太阳能选择性吸收剂（SSA）和热再生电化学循环/制冷机（TRECs-TRERs），以最大限度地利用太阳能。PSC/SnS串联太阳能电池（TSC）具有良好匹配的带隙，可以有效地将更宽的太阳光谱转化为电能，而SSA利用未吸收的光谱成分驱动级联trec - trers，在发电的同时提供额外的冷却。建立了包含不可逆物理和化学过程的数学模型，以阐明TSC与TRECs-TRERs系统之间的相互作用。综合分析确定了影响系统性能的关键参数，包括工作温度、缺陷密度、掺杂密度、接触材料的功函数、再生效率和TRECs-TRERs的内阻。混合动力系统在工作温度波动的情况下保持相对稳定的效率，减轻了典型的高温退化。优化后的参数产生的最大输出功率密度为368.1 W·m-2，最大能量效率为36.81%，比独立PSC提高了57.76%。该研究为高效太阳能热电源集成系统的设计提供了有价值的指导。
