摘要本体异质结有机光伏电池的活性层通常基于包含供体聚合物和基于富勒烯的聚合物电子受体的聚合物共混物。然而，在过去十年中，基于非富勒烯聚合物的太阳能电池取得了快速发展，因为它们具有非凡的化学、热和光稳定性，并且能够降低电压损失。传统的有机光伏电池 (OPV)，基于 P3HT:PCBM 本体异质结 (BHJ) 聚合物混合物或 P3HT/PCBM 双层异质结的结构，效率和稳定性有限，主要是由于富勒烯衍生物用作受体组分。例如，PCBM 与许多其他富勒烯衍生物一样，表现出一些缺陷，例如：有限的化学和能量可调性，吸收光谱范围小，形态不稳定，生产成本相对较高。这就是为什么在过去几年中，为了克服与富勒烯受体相关的上述限制，开始使用新型非富勒烯材料。在本文中，已经测试了两种不同的非富勒烯受体材料作为基于 P3HT 供体聚合物作为主要吸收剂的高效 OPV 的潜在候选材料：一种含有螯合配体如 1,10-菲咯啉 (Phen) 的新型共轭聚合物，以及一种小分子受体，如 5,10,15,20-Tetra(4-pyridyl)-21H,23H-porphine (TPyP)。对于两种电池配置，都获得了电压损失的降低，

On the physical and photo-electrical properties of organic photovoltaic cells based on 1,10-Phenanthroline and 5,10,15,20-Tetra(4-pyridyl)-21H,23H-porphine non-fullerene thin films

Abstract The active layer of the bulk heterojunction organic photovoltaic cells is typically based on a polymeric blend containing a donor polymer and a fullerene-based polymer electron acceptor. However, in the last decade non-fullerene polymer-based solar cells have seen a rapid progress, due to their extraordinary chemical, thermal and photo stability, and because of their ability to decrease the voltage loss. The conventional Organic Photovoltaic Cells (OPVs), structures based on either P3HT:PCBM bulk heterojunction (BHJ) polymeric blend or P3HT/PCBM bilayer heterojunction, have limited efficiency and stability, in principal due to the fullerene derivatives used as acceptor component. PCBM for example, as many other fullerene derivatives, exhibits some deficiencies, such as: limited chemical and energetic tunability, small range of absorption spectra, morphological instability and relatively high production costs. That is why in the last years, novel non-fullerene materials started to be used in order to overcome the above limits associated with the fullerene acceptors. In this paper two different non-fullerene acceptor materials have been tested as potential candidates for the efficient OPVs based on P3HT donor polymer as main absorber: a new conjugated polymer containing chelating ligands like 1,10-Phenanthroline (Phen), and a small-molecule acceptor like 5,10,15,20-Tetra(4-pyridyl)-21H,23H-porphine (TPyP). For both cell configurations a decrease of the voltage loss was obtained, and it was also observed that the thickness of the P3HT donor layer has an important contribution to the output power ( P max ) and fill factor ( FF ) of the OPV structures ( FF and P max increased almost two times by decreasing the thickness of the P3HT donor layer).
