Composites as candidate materials for photovoltaic cells

Abstract

Composites are two or more materials with different properties joined together to manufacture a new material. The resulting physical and chemical properties of each constituent new materials which remain distinct with enhanced properties when compared to the individual constituent materials.With this background, Photovoltaic cells (PV) are very important source of energy in recent years falling under Renewable Energy Resources (RES) meaning that it is abundant in nature, and also environmentally friendly in producing electricity. PV cells contains tiny different types of silicon layers which when the sun shines through it causes reaction between the electrons. In this way, the movement of the electrons through itself and around the circuit generate electricity. Subsequently, the solar cell keeps generating electricity as long as the sun is shining on it. A lot of research has been done and still on-gong on the enhancement of the PV cells to optimize their application. Therefore, the objective of this study is to review and compare the current state-of-the-art articles on different types of composites, which have been used for the PV cells enhancement, especially some twodimensional (2D) materials. Therefore, graphene and MoS used as nanocomposites are considered in this review to support appropriate and informed decisions that are made available to researchers and industries to know the best materials to use going forward in the manufacture of PV cells for better enhancement. Summary of these and more have been presented and prospected in this article.
