Silicon nanostructured based hybrid solar cells have attracted much attention due to their potential advantages of extremely simple device fabrication and the cost-effectiveness of their hybrid structure. These hybrid solar cells open a new research direction in new-generation photovoltaics. Hybrid solar cells made of PEDOT:PSS poly (3,4-ethylenedioxythiophene):poly(styrenesulfonate) and nanostructured silicon have been extensively investigated for the recent development of low-cost solar cells due to their light trapping abilities and simple solution processes. However, the performance of hybrid organic/Si nanostructure solar cells is hindered due to long-term stability and poor coverage of organic material PEDOT:PSS on nanostructure surfaces. There is a growing demand for the development of alternative materials with high-stability and high-conductivity ‘metal-like’ organic molecules.
