Development of Proof of Concept Modules for Concentrator Photovoltaic Receivers

聚光光伏（CPV）是一种很有前途的技术，适用于直射阳光较多的国家。与标准的“平板”模块相比，潜在的能源成本（每千瓦时发电几便士）很低。Narec太阳能光伏技术中心（PVTC）的团队已经为80多家国际公司，大学和机构提供了设计用于聚光运行的硅基太阳能电池超过五年。除了硅太阳能电池的制造和开发外，NSL还生产用于离网应急路边电话和交通管理产品等应用的太阳能模块。在该项目中，NSL将利用其丰富的电池和模块制造经验来开发CPV的概念验证模块。CPV组件需要专门的设计，因为与单一的阳光条件相比，集中的阳光会导致更高的电池温度和更快的紫外线降解薄膜和粘合剂。经过彻底的研究，实验和测试，模块组件，如前片，后片和密封剂将被选择用于CPV模块的概念验证。这些模块将被设计用于许多不同的电池，在不同浓度的阳光下工作，并将进行环境测试，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.
