Silicon is dominating the world in photovoltaic technology. The widely used mono crystalline and poly crystalline wafer technologies are expensive to process. As an alternative, technology of silicon nanocrystals (Si-NCs) is a necessity for economical processing of PV modules. In this work, commercially prepared Si-NCs with a mean diameter of 60 nm is utilized with a pretreatment process followed by functionalization. Styryl and 1-ethenyl-4-fluoro benzyl conjugate moieties are grafted on hydrogen-terminated Si-NCs via hydrosilylation of phenylacetylene and 1-ethyny1-4-fluoro benzene, respectively. Thick-films of these functionalized Si-NCs with different thicknesses are prepared and analyzed in a purposed device architecture at room temperature which reveals a p-type character of functionalized Si-NCs films. Detail analysis of current density voltage U V) characteristics of styryl functionalized Si-NCs films shows that the drifting of charge carriers follows a power law relationship V") in the presence of exponentially distributed trap states. Moreover, a unique voltage dependence of the J V curves also reveals a transition between direct and Fowler Nordheim (F N) tunneling mechanisms.
