    Electrochemically grown ZnO nanorods for hybrid solar cell applications
    (Pergamon-Elsevier Science Ltd, 2010) Hames, Yakup; Alpaslan, Zuehal; Koesemen, Arif; San, Sait Eren; Yerli, Yusuf
    A hybrid solar cell is designed and proposed as a feasible and reasonable alternative, according to acquired efficiency with the employment of zinc oxide (ZnO) nanorods and ZnO thin films at the same time. Both of these ZnO structures were grown electrochemically and poly(3-hexylthiophene):phenyl-C61-butyric acid methyl ester; (P3HT:PCBM) was used as an active polymer blend, which was found to be compatible to prepared indium-tin-oxide (ITO) substrate base. This ITO base was introduced with mentioned ZnO structure in such a way that, the most efficient configuration was optimized to be ITO/ZnO film/ZnO nanorod/P3HT: PCBM/Ag. Efficiency of this optimized device is found to be 2.44%. All ZnO works were carried out electrochemically, that is indeed for the first time and at relatively lower temperatures.

    Manufacturing of inorganic-organic hybrid solar cells by screen printing method
    (2010) Hameş, Yakup; San, Sait Eren; Özdal, Teoman; Aslan, Erdem; Çabalak, Hasip; Şar, Hüseyin
    In this study, hybrid bulk heterojunction (BHJ) organic solar cells with a poly(3-hexylthiophene-2,5- diyl)(P3HT):(6,6)-phenyl $C _{61}$ -butyric acid methyl ester (PC61 BM) active layer, a poly(3,4-ethylenedioxyt- hiophene)-poly(styrenesulfonate)(PEDOT:PSS) buffer layer, and an electrochemically deposited zinc oxide (ZnO) n-type inorganic layer were produced. The PET/ITO/ZnO/PEDOT:PSS/P3HT:PC61 BM/Al device was manufactured and tested under solar illumination (AM1.5G, 100 mW/$Cm^ 2$ ).
