\section{Introduction}\label{sec:intro}
Due to the increasing demand of energy throughout the world during the past decades as well as the pollution provided by conventional energy resources, e.g. oil and coal, it is essential to develop renewable and clean energy resources. Solar energy as an eternal and promising energy source, which has a great potential
