This project is focused on optimizing photovoltaic system performance by integrating an optimum fin configuration for passive cooling. The choice and design of the fin is to ensure the configuration provides optimum passive heat dissipation at low cost towards sustainable energy development and poverty alleviation. With no moving parts this would be free from mechanical problems. As a passive device with no external energy requirements, it provides robust solutions to ensuring the PV system performs optimally in comparatively higher ambient temperature environments where the PV cell temperature can increase more than 30°C above ambient conditions. The reduction in PV cell temperature as is well established in literature, improves the conversion efficiency leading to a comparatively lower unit cost of electricity generated and a shorter payback period on investment. The chosen location for this project is Nigeria in Sub-Saharan Africa where peak ambient temperature ranges between 30.7--36.0°C. Here, almost 40% of the population have no access to electricity with the roughly 60% with access facing challenges of comparatively high cost per kW and intermittent power supply leading to widespread significant use of fossil fuel-based power generators. With anthropogenic greenhouse gas emission increasing global climate change, it is imperative that opportunities for clean renewable energy is explored and developed. Nigeria with all these challenges in electricity generation has abundant solar energy resources. However, this abundant solar resource comes with associated heat that impacts the electricity conversion efficiency of PV cells due to rise in surface temperature. To improve clean energy access in this sub-Saharan African country facing myriad energy problems, we propose the integration of an optimum fin design with PV systems towards passive cooling and enhancement of the conversion efficiency. The purpose is to achieve a lower unit cost of electricity and shorter payback. To achieve this, we will carry out numerical evaluation of the proposed integrated system for its theoretical performance. Once ascertained, a laboratory prototype would be developed and tested under laboratory conditions to ascertain experimental performance. Afterwards, the prototype system will be tested under real conditions in Nigeria to validate its real performance for adoption in the region. Critical to our design is the fins would be made from cheap, available, and highly conductive materials such as aluminium, copper, or a comparative alloy, to ensure that the optimization is done cost effectively with zero maintenance requirements by the end users to encourage its adoption.

这个项目的重点是优化光伏系统的性能，通过集成一个最佳的鳍片配置来进行被动冷却。翅片的选择和设计是为了确保配置以低成本提供最佳的被动散热，以实现可持续能源发展和扶贫。没有活动部件，就不会有机械问题。作为一种无源器件，不需要外部能量，它提供了强大的解决方案，以确保光伏系统在相对较高的环境温度下发挥最佳性能，其中光伏电池温度可高于环境条件30°C以上。正如文献所证实的那样，光伏电池温度的降低提高了转换效率，从而导致相对较低的单位发电成本和较短的投资回报期。该项目的选址是撒哈拉以南非洲的尼日利亚，那里的峰值环境温度在30.7- 36.0°C之间。在这里，几乎40%的人口无法获得电力，而大约60%的人口面临着每千瓦成本相对较高和间歇性电力供应的挑战，导致化石燃料发电机的广泛大量使用。随着人为温室气体排放加剧全球气候变化，探索和开发清洁可再生能源的机会势在必行。尼日利亚在发电方面面临着所有这些挑战，但它拥有丰富的太阳能资源。然而，这种丰富的太阳能资源伴随着相关的热量，由于表面温度的升高，影响了光伏电池的电力转换效率。为了改善这个面临无数能源问题的撒哈拉以南非洲国家的清洁能源获取，我们建议将最佳散热片设计与光伏系统相结合，以实现被动冷却和提高转换效率。其目的是实现更低的单位电力成本和更短的投资回报。为了实现这一点，我们将对所提出的集成系统的理论性能进行数值评估。一旦确定，将开发实验室原型并在实验室条件下进行测试，以确定实验性能。之后，原型系统将在尼日利亚的实际条件下进行测试，以验证其在该地区采用的实际性能。我们设计的关键是鳍片将由廉价、可用和高导电性的材料制成，如铝、铜或相对合金，以确保最终用户在零维护需求的情况下以经济有效的方式进行优化，以鼓励其采用。
