Abstract

Photovoltaic systems encounter significant challenges related to the decline in efficiency due to the high surface temperature. To mitigate these issues, Photovoltaic thermal systems are developed to face the drawbacks of temperature and enhance the overall efficiency. This study examines the overall efficiency of the newly designed PV/T. The new absorber tube featured an inner and outer micro-fin surface absorber tube with broken double V-cuts twisted tapes. This study uses an indoor solar simulator under six different coolants, namely water, 0.4 % CuO, 0.8 % CuO, and the same coolants with 1 % CuO nano-phase change material, to assess the performance of the newly designed collector. The experiment’s test conditions, including irradiances of (400, 550, 700, 850, and 1000) W/m², and flow rates of (0.01, 0.02, 0.03, 0.04, and 0.05) kg/s. The results indicated a proportional relationship between mass flow rates and electrical and thermal performance. The highest electrical and thermal efficiencies were obtained using 0.8 % CuO with nano-phase change material with 12.01 % and 83.61 %, respectively, at an irradiance of 850 W/m² and a flow rate of 0.05 kg/s. Under the same conditions, the maximum power production achieved was 26.01 W.

新设计的内外微翅片表面管双v形扭带破碎光伏集热器的电学和热分析：实验研究

由于表面温度高，光伏系统遇到了与效率下降相关的重大挑战。为了缓解这些问题，开发了光伏热系统，以面对温度的缺点，提高整体效率。本研究考察了新设计的PV/T的整体效率。新型吸收管的特点是内外微翅片表面吸收管带有破碎的双v形切割扭曲带。本研究利用室内太阳能模拟器，在水、0.4% CuO、0.8% CuO和相同的1% CuO纳米相变材料的冷却剂下，对新设计的集热器的性能进行了评估。实验的测试条件为辐照度为（400、550、700、850、1000）W/m2，流速为（0.01、0.02、0.03、0.04、0.05）kg/s。结果表明，质量流量与电学和热学性能成正比关系。在辐照度为850 W/m2，流速为0.05 kg/s的条件下，当CuO含量为0.8%，纳米相变材料含量为12.01%和83.61%时，获得了最高的电效率和热效率。在相同条件下，最大输出功率为26.01 W。
