将半透明有机太阳能电池（ST-OSC）添加到温室结构中可以同时实现植物栽培和发电，从而减少温室能源需求。然而，有必要确定这种系统对植物生长和室内气候的影响，并优化系统的权衡。在这项工作中，我们考虑植物生长下的OSC和系统相关的设计。我们评估了ST-OSC滤光片下红叶生菜的生长，并比较了具有独特透射率的三种不同OSC活性层的影响。我们发现，在这些OSC过滤器下生长的生菜的鲜重和叶绿素含量没有显着差异。此外，OSC通过设备设计和光学涂层为温室的进一步光和热管理提供了机会。因此，OSC可以影响植物生长，发电，温室的热负荷，这种设计的贸易空间进行审查和举例说明。
Adding semitransparent organic solar cells (ST-OSCs) to a greenhouse structure enables simultaneous plant cultivation and electricity generation, thereby reducing the greenhouse energy demand. However, there is a need to establish the impact of such systems on plant growth and indoor climate and to optimize system tradeoffs. In this work, we consider plant growth under OSCs and system-relevant design. We evaluate the growth of red leaf lettuce under ST-OSC filters and compare the impact of three different OSC active layers that have unique transmittance. We find no significant differences in the fresh weight and chlorophyll content of the lettuce grown under these OSC filters. In addition, OSCs provide an opportunity for further light and thermal management of the greenhouse through device design and optical coatings. The OSCs can thus affect plant growth, power generation, and thermal load of the greenhouse, and this design trade space is reviewed and exemplified.
