摘要

太阳能光伏能源是各国实现其能源矩阵更大多样性的主要可再生能源替代品之一。它受益于高水平的入射太阳辐照度。然而,随之而来的温度升高,加上其他环境变量,降低了它的总产量。一种冷却方法是使用热电或珀尔帖电池。本文旨在研究一种混合系统,该系统寻求通过热电电池的主动冷却来增加光伏组件的产量。研究策略包括评估控制温度、给定光伏组件的热电电池数量、使用最大功率跟踪算法以及控制热电电池电源以达到最佳运行点。这项研究使用数学模型和模拟表明,在研究的情况下,使用热电电池冷却光伏组件可以将其产量提高7%。

Development of a Hybrid PV-Thermoelectric System
The solar photovoltaic energy is one of the main renewable energy alternatives for countries to achieve a greater diversity in their energy matrix. It benefits from high levels of incident solar irradiance. However, the increase in temperature that comes with it, allied to other environmental variables lowers its overall yield. One cooling option is to use thermoelectric, or Peltier cells. This paper aims to study a hybrid system that seeks an increase of a photovoltaic module yield through its active cooling by a thermoelectric cell. Research strategies include evaluation of controlled temperature, number of thermoelectric cells for a given photovoltaic module, use of maximum power tracking algorithms together with control of the thermoelectric cells power supply to achieve an optimum point of operation. This study uses mathematical models, and simulations to show that the use of thermoelectric cells to cool off the photovoltaic module can increase its yield by up to 7% in the cases studied.
