Development of Proof of Concept Modules for Concentrator Photovoltaic Receivers

集中式光伏(CPV)是一种很有前途的技术，适用于阳光直射程度较高的国家。与标准的平板模块相比，潜在的能源成本(每千瓦时发电量的便士)更低。Narec Solar光伏技术中心(PVTC)的团队一直在向80多家国际公司、大学和机构提供硅基太阳能电池，这些电池旨在集中运行五年以上。除了硅太阳能电池的制造和开发，NSL还为离网紧急路边电话和交通管理产品等应用制造One SUN模块。在这个项目中，NSL将利用他们丰富的电池和模块制造经验为CPV开发概念验证模块。CPV模块需要专门的设计，因为与单日照条件相比，集中的阳光会导致更高的电池温度和更快的薄膜和粘合剂的紫外线降解。经过深入的研究、实验和测试，将选择前片、后片和密封剂等模块组件作为概念验证CPV模块。这些模块将为许多不同的电池设计，在不同的阳光浓度下运行，它们将进行环境测试，以确保长期的可靠性。

Concentrator Photovoltaics (CPV) is a promising technology for countries with high direct sunlight. The potential cost of energy (pence per kWh of electricity generated) is low compared to standard 'flat plate' modules. The team at Narec Solar’s Photovoltaic Technology Centre (PVTC) have been providing silicon based solar cells designed to operate under concentration for over five years to more than 80 international companies, universities and institutions. In addition to silicon solar cell manufacture and development, NSL manufacture one sun modules for applications such as off grid emergency roadside telephones and traffic management products.In this project NSL will utilise their extensive cell and module manufacturing experience to develop proof of concept modules for CPV. CPV modules require specialised design since concentrated sunlight leads to higher cell temperatures and more rapid UV degradation of films and adhesives, compared to one sun conditions. Following thorough research, experimentation and testing, module components such as front sheets, back sheets and encapsulant will be selected for proof of concept CPV modules. These modules will be designed for a number of different cells operating at varying concentrations of sunlight and they will be environmentally tested to ensure long term reliability.
