Abstract

ABSTRACT Photovoltaics (PV) have admittedly seen substantial advancements during the last decades. Improvements in the performance of conventional technologies as well as the emergence of cost effective alternatives facilitated its establishment as a major contributor towards the adoption of a green power production model. Nevertheless, photovoltaics still suffer from efficiency issues, mainly related to performance dependency upon operating temperature. For perovskite cells, it is also crucial to maintain temperature below a defined threshold to avoid premature degradation. Photovoltaic-thermoelectric hybridization has been recently proposed as a means of restricting excessive temperature increase, reducing recombination and improving the overall efficiency response. In this work, the performance of a hybrid photovoltaic-Peltier system is examined through an analytical modelling approach. Different thermoelectric coolers (TECs) and PV cell types have been studied. Furthermore, a sensitivity analysis has been conducted in order to identify the most critical parameters for obtaining optimum coupling between PV and TEC technologies.

光电器件和Peltier冷却器的最佳耦合，以提高性能和稳定性

在过去的几十年里，光伏发电(PV)取得了巨大的进步。传统技术性能的改进以及成本效益高的替代办法的出现，促进了它成为采用绿色电力生产模式的主要贡献者。然而，光伏电池仍然存在效率问题，主要与工作温度对性能的依赖有关。对于钙钛矿电池来说，保持温度低于定义的阈值以避免过早降解也是至关重要的。近年来，光电热电杂交技术被提出作为一种限制温度过高升高、减少复合和提高整体效率响应的手段。在这项工作中，通过分析建模方法检查了混合光伏-珀尔帖系统的性能。研究了不同的热电冷却器(tec)和光伏电池类型。此外，还进行了敏感性分析，以确定获得PV和TEC技术之间最佳耦合的最关键参数。

期刊介绍： Engineering and sustainable development are intrinsically linked. All capital plant and every consumable product depends on an engineering input through design, manufacture and operation, if not for the product itself then for the equipment required to process and transport the raw materials and the final product. Many aspects of sustainable development depend directly on appropriate and timely actions by engineers. Engineering is an extended process of analysis, synthesis, evaluation and execution and, therefore, it is argued that engineers must be involved from the outset of any proposal to develop sustainable solutions. Engineering embraces many disciplines and truly sustainable solutions are usually inter-disciplinary in nature.
