摘要

摘要 光电超级电容器(PSC)是一种独立的能源,可同时实现光电转换和能量存储。要在这些集成系统中实现更高的效率,就必须深入了解 PSC 的工作原理,因此非常有必要进行理论分析。本文对由 CdS/CdTe 薄膜太阳能电池和超级电容器组成的 PSC 进行了理论研究。太阳能电池的器件物理特性采用 Sah-Noyce-Shockley (SNS) 理论,超级电容器的工作则采用电路模型。PSC 充电的时间演化由集成电路微分方程进行理论模拟,并使用数值方法求解。研究了太阳能电池因素对 PSC 充电的影响。通过优化太阳能电池参数,拟议的 PSC 可实现约 8.8% 的最大能量转换和存储效率 (ECSEmax %)。

Investigations on Integration of CdS/CdTe Thin Film Solar Cell with Supercapacitor

Photo-supercapacitors (PSCs) are independent energy sources serving the cause of simultaneous photoelectric conversion and energy storage. Insights on the working of PSCs are inevitable to realize higher efficiencies in these integrated systems and so theoretical analyses are highly required. A theoretical study on PSC comprising a CdS/CdTe thin film solar cell with a supercapacitor is carried out. The device physics of the solar cell is characterized by Sah-Noyce-Shockley (SNS) theory and the Electrical Circuit Model is used to model the working of supercapacitor. The temporal evolution of the PSC charging is theoretically simulated by the differential equation of the integrated circuit, solved using numerical methods. The effect of solar cell factors on the PSC charging is studied. With the optimized solar cell parameters, the maximum value of Energy Conversion and Storage Efficiency (ECSEmax %) of about 8.8% can be achieved with the proposed PSC.
