Organic photovoltaic cells are a promising technology for generating renewable energy from sunlight. These cells are made from organic materials, such as polymers or small molecules, and can be lightweight, flexible, and low-cost. Here, we have created a novel mixture of magnesium phthalocyanine (MgPc) and chlorophenyl ethyl diisoquinoline (Ch-diisoQ). A coating unit has been utilized in preparing MgPc, Ch-diisoQ, and MgPc-Ch-diisoQ films onto to FTO substrate. The MgPc-Ch-diisoQ film has a spherical and homogeneous surface morphology with a grain size of 15.9 nm. The optical absorption of the MgPc-Ch-diisoQ film was measured, and three distinct bands were observed at 800-600 nm, 600-400 nm, and 400-250 nm, with a band gap energy of 1.58 eV. The current density-voltage and capacitance-voltage measurements were performed to analyze the photoelectric properties of the three tested cells. The forward current density obtained from our investigated blend cell is more significant than that for each material by about 22%. The photovoltaic parameters (Voc, Isc, and FF) of the MgPc-Ch-diisoQ cell were found to be 0.45 V, 2.12 μA, and 0.4, respectively. We believe that our investigated MgPc-Ch-diisoQ film will be a promising active layer in organic solar cells.
有机光伏电池是一种很有前途的技术，可以利用阳光产生可再生能源。这些电池由有机材料制成，如聚合物或小分子，并且可以是轻量级的、灵活的和低成本的。在这里，我们创造了一种新型的镁酞菁（MgPc）和氯苯基乙基二异喹啉（Ch-diisoQ）混合物。我们使用一个涂层单元在 FTO 衬底上制备 MgPc、Ch-diisoQ 和 MgPc-Ch-diisoQ 薄膜。MgPc-Ch-diisoQ 薄膜具有球形和均匀的表面形态，晶粒尺寸为 15.9nm。测量了 MgPc-Ch-diisoQ 薄膜的光学吸收，在 800-600nm、600-400nm 和 400-250nm 处观察到三个明显的带，带隙能为 1.58eV。进行了电流密度-电压和电容-电压测量，以分析三个测试电池的光电性能。我们研究的混合电池获得的正向电流密度比每个材料的正向电流密度高约 22%。MgPc-Ch-diisoQ 电池的光伏参数（Voc、Isc 和 FF）分别为 0.45V、2.12μA 和 0.4。我们相信，我们研究的 MgPc-Ch-diisoQ 薄膜将成为有机太阳能电池中很有前途的活性层。
