摘　　要：【目的】野外作业和户外生存对能源的需求越来越大,现有常规供能方式存在一些重要缺陷,例如常规发电机需携带大量燃油、蓄电池重量大等。太阳能光伏/光热(photovoltaic/thermal,PV/T)发电技术可有效解决户外生存和野外作业能源缺乏的问题,而现有的PV/T集热器多为刚性结构、重量大而不便于携带。【方法】提出一种基于铜铟镓硒薄膜电池和毛细管网相结合的轻薄型PV/T组件,通过实验的方法研究该组件的集热性能及水流量对组件光电、光热转换效率的影响。【结果】在典型上海气候下,该组件的全天电效率、热效率分别为13.04%、22.50%;在平均辐照度为760 W/m^(2)的实验条件下,水流量为2.1 L/min时,此PV/T的集能性能最优;毛细管网内冷却水可有效降低电池温度(10℃)、提高能量利用效率(23.94%)。【结论】该组件具有高功率密度、轻便灵活的特点,可用于野外作业、户外生存时的能源供给,为户外能源装备的设计提供了新思路。[Objectives]The demand for energy in outdoor work and survival is increasing,and there are some significant shortcomings in the existing conventional energy supply methods,such as the need to carry a large amount of fuel for conventional generators and heavy weight of cells.Solar photovoltaic/thermal(PV/T)technology can effectively solve the problem of lack of energy for outdoor survival and field work.However,most of the existing PV/T collectors are rigid structures with large weight and are not easy to carry.[Methods]A light and thin PV/T module based on the combination of a Cu(In,Ga)Se2(CIGS)thin film battery and a piece of capillary network were proposed.The energy collection performance of the module and the impact of water flow rate on the photoelectric and photothermal conversion efficiency of the module were studied experimentally.[Results]Under the typical Shanghai climate conditions,the all-day electrical efficiency and thermal efficiency of the module are 13.04%and 22.50%,respectively.Under experimental conditions with an average irradiance of 760 W/m^(2),the optimal energy collection performance of this PV/T is achieved when the water flow rate is 2.1 L/min.The cooling water in the capillary network can effectively reduce the cell temperature(by 10℃)and improve the energy utilization efficiency(by 23.94%).[Conclusions]The module has the characteristics of high power density,light weight and flexibility,and can be used for energy supply during outdoor work and survival,providing a new idea for the design of outdoor energy equipment.
