Thermal behaviour of Silicon Solar cells in low-concentration quasi-static PV systems and impact of high temperature on their photoconversion performance

Innovative Solar Power （ISP）开发了一种准静态太阳能聚光系统，该系统结合了聚光系统的高功率转换优势和静态安装的低成本，无需昂贵的太阳跟踪元件。这种系统的估计成本相当于今天典型安装价格的25%。该公司已经花费了大约100万美元来开发这项新技术，制作原型并展示其概念的潜力。然而，为了使ISP系统商业化，有必要对其可靠性进行评估，因为该参数是与标准pv技术在投资盈利能力估计方面进行比较的基础。在这个项目中，我们将研究作为系统重要组成部分的硅太阳能电池的可靠性。由于接收器及其硅光电转换器位于聚光镜的焦轴上，因此它们将暴露在高温下。在这个项目中，我们将研究温度对系统性能的影响及其对太阳能电池老化和ISP系统性能的影响。

Innovative Solar Power (ISP) has developed a quasi-static solar concentration system that combines theadvantage of high power conversion of concentrating systems with low cost of static installations withoutexpensive sun tracking elements. The estimated cost of such system is equal to 25% of price of today's typicalinstallations. The company has spent as far approximately $1M to develop this new technology, to fabricateprototypes and to demonstrate the potential of their concept. However, in order to commercialize ISP systems,it is necessary to evaluate their reliability, since this parameter is fundamental for comparison with standard PVtechnology in terms of investment's profitability estimation. In this project, we will study the reliability of thesilicon solar cells, which are important components of the system. Since the receiver, with its silicon photoconverter, are in the focal axis of the concentrating mirrors, they will be exposed to a high temperature.In this project we will investigate the effect of temperature on the system performance and its impact on solarcells aging and on ISP system performances.
