Photosynthesis and semiconductor-based solar cells Over time plants have come up with possibly the most proficient power supply in the world. This power supply is known as photosynthesis. This is the transfer of sunlight, carbon dioxide and water into utilizable power, giving off oxygen along the way. When it comes to plants, usable fuel comes in the form of proteins, fats and carbohydrates. People, alternatively, are looking for liquid power in order to run things like cars and refrigerators. Scientists believe that trying to artificially recreate photosynthesis can be a way to solve the expensive and dwindling energy issues that society faces today (Layton, 2012). "For years, scientists have been trying to come up with a way to use the same energy system that plants do but with an altered end output. Using nothing but sunlight as the energy input, plants execute massive energy conversions, turning billions of CO2 into energy for animals in the form of food, every year, using only 3% percent of the sunlight that reaches Earth" (Layton, 2012). The power that is accessible in sunlight is an under used source that has only just lately started to truly be assessed. Present photovoltaic-cell technology, which is characteristically a semiconductor-based system, is very pricey, not very adept, and only does direct alterations to electricity from sunlight. There problem is that is that there is currently no way for the energy output to be stored for later use. One way to
