Abstract

In this study, graphene oxide (GO) was prepared by the modified Hummers method. Later the synthesized graphene oxide was reduced to reduced graphene oxide (RGO) by the chemical reduction process. In summary, the pure TiO2 and TiO2-graphene composite photoanode based quantum dot sensitized solar cells have been fabricated by the one-step method of electrospinning technique. The solar cells fabricated have been measured short current density (Jsc) and open-circuit voltage (Voc). The short current densities of TiO2 and TiO2-RGO-based composite quantum dot solar cells are 0,672 mA/cm2 and 0,770 mA/cm2 , respectively. In addition, admittance spectroscopy of solar cells were measured in a variable frequency ranges of 10 kHz-10 MHz. The fabricated of solar cells were investigated the capacitance-voltage (C-V), conductance-voltage (G/ω-V) characteristics by attention the series resistance (Rs) effect.

Özet

Bu çalışmada öncelikle modifiye Hummers metodu kullanılarak grafen oksit (GO) üretilmiştir. Üretilen grafenoksit kimyasal yolla indirgenerek, indirgenmiş grafen oksit (RGO) sentezlenmiştir. Sentezlenen RGO ve TiO2çözeltileri kullanılarak tek adım elektro eğirme yöntemi ile saf TiO2 ve TiO2-RGO tabanlı fotoanaot yüzeyleresahip kuantum nokta duyarlı güneş pilleri üretilmiştir. Üretilen güneş pillerinin kısa devre akım yoğunluğu (Jsc) veaçık devre gerilimi (Voc) ölçümleri yapılmıştır. Saf TiO2 fotoanota sahip güneş pilinin kısa devre akımı yoğunluğu0,672 mA/cm2, TiO2-RGO kompozit fotoanota sahip güneş pilinin ise 0,770 mA/cm2 olarak ölçülmüştür. Ayrıcagüneş pillerinin admitans spektroskopisi 10 kHz-1MHz frekans aralığında ölçülmüştür. Üretilen güneş pillerininkapasite-voltaj (C-V), iletkenlik-voltaj (G-V) karakteristikleri seri direnç etkisi dikkate alınarak incelenmiştir.
