This research paper aims to study the carrier transport mechanisms and photovoltaic properties of the SiPcCl2 thin film. To achieve this, Au/silicon phthalocyanine dichloride (SiPcCl2)/p-Si/Al heterojunction device was prepared. The heterojunction microelectronic parameters such as ideality factor, m and reverse current Is were estimated at room temperature and found to be 6.77 and 408 nA respectively. The series resistance Rs of the fabricated device was also calculated. Two mechanisms were deduced in SiPcCl2/p-Si according to the voltage range. The results revealed that the height of effective barrier $$\varphi_{bi}$$ is clearly increased from 0.71 to 0.80 eV. Moreover, the photovoltaic properties of Au/SiPcCl2/p-Si/Al cell were studied under illumination such as the short circuit current, Isc, open circuit voltage, Voc, maximum current IM, maximum voltage, VM, filling factor FF and power conversion efficiency, η were measured to be 0.59 mA, 0.47 V, 0.44 mA, and 0.24 V, 0.40 and 3.7% respectively. The topographical properties of the SiPcCl2 thin film deposited on the flat glass substrate were investigated using atomic force microscope method.
