为了解决太阳能的关键问题，当前的研究重点是开发低成本、轻质且环保的先进太阳能收集材料。在许多有机光伏（PV）中，卟啉化合物表现出独特的结构特征，具有强烈的紫外线（UV）和近红外吸收以及高平均可见光透射率，使其成为太阳能应用的理想选择。卟啉化合物还被发现具有很强的光热（PT）效应，最近被应用于建筑表皮的光学隔热。卟啉化合物的这些结构和光学特性使其能够在充分收集太阳能的情况下充当 PT 或 PV 器件。可以开发具有 PT 和 PV 双模态的透明卟啉薄膜，用于将阳光转化为电能或热能，并可根据能源消耗需求进行改变。建筑表皮可以设计成具有 PT 和 PV 双模态的有源装置，用于大规模能量收集、节约和发电。本综述提供了叶绿素和叶绿酸等卟啉化合物的 PT 和 PV 特性的最新实验结果。他们的 PT 和 PV 机制与其电子结构相关进行讨论。还讨论了卟啉化合物的合成路线、薄膜沉积和势能应用。
To address the critical issues in solar energy, the current research has focused on developing advanced solar harvesting materials that are low cost, lightweight, and environmentally friendly. Among many organic photovoltaics (PVs), the porphyrin compounds exhibit unique structural features that are responsible for strong ultraviolet (UV) and near infrared absorptions and high average visible transmittance, making them ideal candidates for solar-based energy applications. The porphyrin compounds have also been found to exhibit strong photothermal (PT) effects and recently applied for optical thermal insulation of building skins. These structural and optical properties of the porphyrin compounds enable them to function as a PT or a PV device upon sufficient solar harvesting. It is possible to develop a transparent porphyrin thin film with PT- and PV-dual-modality for converting sunlight to either electricity or thermal energy, which can be altered depending on energy consumption needs. A building skin can be engineered into an active device with the PT- and PV-dual modality for large-scale energy harvesting, saving, and generation. This review provides the current experimental results on the PT and PV properties of the porphyrin compounds such as chlorophyll and chlorophyllin. Their PT and PV mechanisms are discussed in correlations to their electronic structures. Also discussed are the synthesis routes, thin film deposition, and potential energy applications of the porphyrin compounds.
