本研究详细分析了地中海气候下塑料隧道式温室屋顶上有机光伏 (OPV) 面板的户外行为，研究了环境变量和面板方向对面板电气行为和退化的影响，从而提供了该气候地区温室集成 OPV 的重要户外测试结果。放置在屋顶塑料隧道屋脊上的 OPV 面板在测量期间产生了最高的输出、效率和填充系数。然而，在温室屋顶的东侧和西侧使用面板可以减少中午的输出峰值，从而在全天提供更平衡的电力供应。OPV 行为的日变化受到辐照度和温度变化的同时影响。研究发现，尽管输出较高，但 OPV 在高入射辐照度下有时会表现出填充因子和效率下降。这被认为是由于高直接辐照条件下的可逆退化现象造成的，这导致早上的性能比下午更高，随后在夜间和一定程度上在阴凉条件下恢复。
This study presents a detailed analysis of the outdoor behaviour of organic photovoltaic (OPV) panels on a polytunnel type greenhouse roof in a Mediterranean climate, looking at the effects of environmental variables and panel orientations on the electrical behaviour and degradation of the panels, thus providing crucial outdoor testing results of greenhouse integrated OPVs in this climatic region.The OPV panel placed at the polytunnel ridge of the roof yielded highest outputs, efficiencies and fill factors during the measurement period. However, the use of panels on the East and West sides of the greenhouse roof, could reduce midday output peaks and therefore provide a more balanced power supply throughout the day.The diurnal variation in OPV behaviour was influenced by simultaneous effects of changing irradiance and temperature. It was found that although output was higher, the OPVs showed dips in fill factor and efficiency at times with high incident irradiance. This was assumed to be due to a reversible degradation phenomenon under high direct irradiance conditions, which led to higher performance during morning hours compared to the afternoon and was followed by a recovery overnight and to some extent in shaded conditions.
