Increasing populations of about 29.24 million people in Malaysia along with rapid improvement and development results in increasing of the energy usage demands [1]. It is estimated that primary sources of energy consumption in the world is 86.4 % from fossil fuels which consists of 36.0 % from petroleum, 27.4 % from coal, 23.0 % from natural gas [2]. However, fossil fuels energy sources are non-renewable and also contribute to pollution. In order to fulfill the needs of energy used, solar light is expected to become a leading next-generation for clean and sustainable energy resources. The main interest of solar energy over other energy sources is that sunlight can be directly harvested into solar energy with the use of small and tiny photovoltaic (PV) solar cells [3].
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
