Comparative study for using chlorophyll extracted from green leaves for solar cell fabrication after treatment with other materials

摘要

A solar cell or photovoltaic cell is a device which generates electricity directly from visible light. However, the Gratzel solar cells' efficiency is fairly low. So, it costs expensive according to other energy resources products. There is several factors affect gratzel solar cell efficiency which formed from chlorophyll. This research work is a comparative study between Grätzel chlorophyll solar cells and chlorophyll solar cells extracted from different plants after different types of treatment to enhance its efficiency, current, voltage and durability. We aim that, this study has moved a step closer to overcoming one of the troubles to manufacture a low cost solar cell from plant with low price, high voltage, current and long durability
