In the event of disasters, the provision of energy encounters significant challenges. Flexible photovoltaic (FlexPV) is an ideal choice for emergency shelters to supply the daily activities for displaced populations. S(P)EEDKITS is a project to develop rapid deployable emergency shelters as seeds of self-recovery. Based on the project, this study is to assess the feasibility of FlexPV on the roof of emergency shelters. Various measurements have been conducted on a multipurpose tent to investigate the reliability of the flexible solar cells, thermal performance, acoustic performance, and power generation in the winter solstice. From the results, the Electroluminescence tests show that serious microcracks occur on the FlexPV cells after a long-term application, which is hidden danger for power output. I-V tests show the degradation of PCE is within 2.8 % after one year usage Moreover, the energy yield during the winter solstice is sufficient to fulfill the minimum power requirement essential for the effective operation of the emergency shelter in Milan. Additionally, the integration of FlexPV panels causes an average 8.6 °C temperature increase, showing a negative influence on the power output of FlexPV. Finally, the integration leads to a 6.7 % increase of the indoor noise. So, the FlexPV panels are more suitable to be applied for a short period of time after disaster to solve the energy crisis of disaster victims.

灾后应急避难所供能柔性光伏板性能评价



在发生灾害时,能源供应面临重大挑战。柔性光伏 (FlexPV) 是紧急避难所的理想选择,可为流离失所者提供日常活动。S(P)EEDKITS 是一个开发可快速部署的紧急避难所作为自我恢复种子的项目。基于该项目,本研究旨在评估 FlexPV 在紧急避难所屋顶上的可行性。已经对多功能帐篷进行了各种测量,以研究柔性太阳能电池的可靠性、热性能、声学性能和冬至发电量。从结果表明,电致发光测试表明,FlexPV 电池在长期应用后会出现严重的微裂纹,这对功率输出存在隐患。I-V 测试显示,使用一年后 PCE 的降解率在 2.8% 以内此外,冬至期间的发电量足以满足米兰紧急避难所有效运行所必需的最低电力要求。此外,FlexPV 面板的集成会导致平均温度升高 8.6 °C,对 FlexPV 的功率输出产生负面影响。最后,集成导致室内噪声增加 6.7%。因此,FlexPV 面板更适合在灾后短时间内应用,以解决灾民的能源危机。
