Is the Electrolysis New Science in Solar Cells?
Green energy systems are becoming more and more popular in our daily lives. Whether they’re electric water heaters, water purifiers, or even washing machines, their benefits are incredible.
A few years ago, the concept of converting sunlight into energy was well known, but buying solar panels had not really hit the market cheap enough for mass amounts of people to buy. Now, a new kind of technology is on the market, which can do this for you.
The guys from MIT, led by Professor Alan Heeger, developed a solar cell that can harvest excess light from the sun, and convert it into usable energy.
The technology was inspired by the photosynthetic cells that are found in the water molecules in our oceans, which convert carbon dioxide into oxygen and vice versa. The principle behind it is extremely simple, which makes it a good candidate for large-scale applications.
Heeger and his team designed a solar cell that uses sunlight to split water molecules apart, releasing the light and oxygen through the process of photosynthesis. The theory behind it is that in order to do this, the cell needs to absorb energy from the environment. This process is called photoelectrochemical reduction and it’s already in use.
The new solar cell takes advantage of the fact that the air in water molecules can be divided into hydrogen and oxygen using an electrochemical process called electrolysis. The process is very simple and cheap too, making it a good candidate for the production of hydrogen from water.
The researchers combined the oxygen and hydrogen with a metal ion (molybdenum) through a electrolyzer, which makes it possible to mass-produce hydrogen through the production of electricity.
The final product of this process is water, which can be used as a source of hydrogen for industrial processes, and as an energy storage device. The guys have also used it to produce electricity using the process. The final product was presented as a gold-cured cellulose compound, which can be used in cement, food, and other products.
The price of the process is only $20/mole. They also made a solar cell that uses recycled water, as a source of hydrogen.
The development of solar cells is expensive, but this cost has dropped a little.
