Abstract:

The efficacy of modified Aluminothermic processed Si-NPs to improve the photovoltaic performance of spin coated copper oxide/zinc oxide (CuO/ZnO) heterojunction solar cell deposited on FTO using simple spin coating technique has been investigated in this contribution. At first, copper oxide was directly synthesized from its acetate through solution process and silicon Nano-particles (Si-NPs) were prepared by ultra-sonication of extracted silicon from Padma river sand through Magnesio-Aluminothermic (modified alumino-thermic) reaction. After that, thin films of CuO and Si-NPs doped CuO are deposited through simple and inexpensive spin coating technique. X-ray diffraction (XRD), Energy Dispersive X-ray Spectroscopy (EDX), ultraviolet-visible spectroscopy (UV-Vis) and thickness profilometer were used to characterize the deposited films. Photovoltaic performance of Si-NPs doped CuO as an absorber of metal oxide ZnO/CuO based inorganic heterojunction solar cells also studied. Experimental results show that, Si-NPs have improved the optical and electrical properties of CuO noticeably. Optical absorbance of NPs-CuO thin film is increased ~21%. The photo conversion efficiency of FTO/ZnO/Si-NPs-CuO/Al heterostructure solar cell is enhanced from η= 0.96 % to η= 1.37 % for the using of Si-NPs with absorber CuO.  With no anti-reflection coating, hole transport layer and electron transport layer, this value of inorganic heterojunction solar cell efficiency is one of the highest reported value for a ZnO/CuO interface formed in air using spin coating technique.
