Abstract
Organik güneş hücrelerinin performansları üzerinde yüzey modifikasyonu ve metal nanopartiküller önemli bir rol oynamaktadır. Tek tabaka kendiliğinden organize olan (self assembly monolayer, SAM) organik malzemeler ucuz ve kolay uygulanabilir olmaları nedenleriyle diğer yüzey uygulama tekniklerine alternatif bir malzemelerdir. Metal nanopartiküllerin organik güneş hücrelerinde uygulama alanlarının geliştirilmesi son yıllarda önemli bir başlık haline gelmiştir. Bu çalışmada, sol-jel yöntemi ile sentezlenen TiO2 elektrot yapısına Ag np’ler katkılanmış ve Ag-/TiO2 yüzeyi SAM molekülü ile modifiye edilerek yeni bir tür elektrot tasarlanmıştır. TiO2 elektrotlu güneş hücresinde elde edilen verimlilik değeri % 2,25 iken, bu çalışmada tasarlanan Ag-TiO2/SAM elektrot yapısından elde edilen güneş hücre verimliliği % 2,84 olarak bulunmuştur.
Surface modification and metal nanoparticles, play an important role on the performance of organic solar cell. Organic materials of self assembly monolayer (SAM) is a alternative material to other surface application techniques due to their cost effective and easy processing. The development of application area of metal nanoparticles, have become an important issue in organic solar cells. In this study, TiO2 electrode, synthesized by sol-gel method, was doped with Ag np's and a novel electrode was designed by modification Ag-TiO2 surface with SAM. While the efficiency of organic solar cell with TiO2 electrode was obtained as 2,25%, the value of efficiency was found as a 2,84% by the use of designed Ag-TiO2/SAM electrode
