Aluminum Phthalocyanine Chloride (AlPcCl) is generally known as donor material in organic photovoltaic cells (OPVs). Nevertheless, in the present study we have demonstrated a successful use of AlPcCl as acceptor material to replace fullerene (C₆₀) in a planar heterojunction OPVs based Alpha-Sexithiophene (α-6T) as donor material. For this purpose, we have elaborated two series of OPVs: α-6T/AlPcCl and α-6T/C₆₀ using thermal sublimation technique. After the optimization of the AlPcCl thickness we have compared both solar cells current density vs. voltage characteristics, we have shown that the use of AlPcCl as acceptor instead of C₆₀ induces to an increase in the open circuit voltage (V_oc) and the short current density (J_sc) values by 18% and 23%, respectively, from 0.5 to 0.61 V and from 6.10 to 7.98 mA/cm², while, we have obtained a decrease in the shunt resistance which has dropped the fill factor (FF) from 58 to 51%. The V_oc and J_sc increase allows to increase the power conversion efficiency by 28%. These findings have been supported by absorbance measurements and morphological studies. The V_oc and J_sc increase have been discussed and assigned to the difference between the theoretical V_oc of both heterojunctions, and to the complimentary absorption of AlPcCl with α-6T. While, the FF deceases has been attributed to the low electron mobility of AlPcCl compared with C₆₀. These findings, brought in the spotlight the potential of the metal phthalocyanines, which can open up a wide range of possibilities to test other materials based like this family.

铝酞菁氯化物 (AlPcCl) 通常被认为是有机光伏电池 (OPV) 中的供体材料。尽管如此，在本研究中，我们已经证明了在基于 α-六噻吩 (α-6T) 作为供体材料的平面异质结 OPV 中，成功使用 AlPcCl 作为受体材料来替代富勒烯 (C ₆₀ )。为此，我们制定了两个系列的 OPV：α-6T/AlPcCl 和 α-6T/C ₆₀使用热升华技术。在优化 AlPcCl 厚度后，我们比较了两种太阳能电池的电流密度与电压特性，我们已经表明使用 AlPcCl 作为受体而不是 C _{60 会}导致开路电压 (V _oc ) 和短路的增加。电流密度（J_sc ) 值分别从 0.5 到 0.61 V 和从 6.10 到 7.98 mA/cm ²降低了 18% 和 23%，同时，我们已经获得了分流电阻的降低，这使填充因子 (FF) 从 58 下降到51%。V _oc和 J _{sc 的}增加允许将功率转换效率提高 28%。这些发现得到了吸光度测量和形态学研究的支持。已经讨论了V _oc和 J _{sc 的}增加，并将其归因于两种异质结的理论 V _oc之间的差异，以及 AlPcCl 与 α-6T 的互补吸收。而 FF 的下降归因于与 C ₆₀相比 AlPcCl 的低电子迁移率. 这些发现使金属酞菁的潜力成为人们关注的焦点，它可以为测试类似该系列的其他材料开辟广泛的可能性。
