Having the opportunity to see beyond our field of study was a great experience. That was what happened when Dr. Ferrer and Dr. Velázquez presented their work on a photosynthesis analog method. It really amazed me to see how they used a leaf as inspiration to create an analog process of photosynthesis, a process that converts sunlight, water, and carbon dioxide into carbohydrates and oxygen, transforming solar energy into chemical energy using the leaf as the transforming facility. As they show this artificial leaf will differ from the natural leaf by producing hydrogens molecules sunlight.

Subsequently, we prepared a cathode (covering with graphite), cleaned the electrode with Ethanol, and assembled the finished anode conductive side and the cathode conductive side with binder clips. To test the cells we used a light source. It was a great experience seeing our solar cell voltage when it was hit by light. This lab provided us with the opportunity to explore the photovoltaics and efficiency of this lab made solar cell.
