In this paper, we study on the effects of ZnO nanorods /seed ZnO on properties of hybrid solar cells. ZnO nanorods fabricated by electrochemical method of two-step stable flow of liquid Zn(NO3)2. 6H2O (0.005 M) and C6H12N4 (0.005 M). Morphology and optoelectronic properties of ZnO nanorods were studied by SEM images, UV-VIS transmission spectra, X-ray diffraction and photoluminescence spectrum. Elaboration of hybrid solar cells by inserting ZnO nanorods on organic photoactive layer of P3HT:PCBM and ITO, as result the solar cell conductivity performance is significantly improved. Experimental results show that ~ 1,392 mA/cm2 Jsc, Voc ~ 0.49 V, FF = 0.32, and PCE = 0.23%.

In this paper we investigated the effect of Hexamethylenetetramine (HMTA, C6H12N4) concentration on the growth of ZnO nanorods on ITO substrates and the influence of the ZnO seed layer on its orientation growth. ZnO nanorods were synthesized by the two-step method of stable flow electrochemical method of saline solution Zn(NO3)2 at 90oC. As result, the high hexagonal crystalline ZnO nanorods were well oriented according to the (002) lattice network. The change of amperage and electrolysis time have show the effetive control of morphology and size of ZnO nanorods which has been studied by XRD and SEM images
