Environment-Friendly Solar Cells to consume natural energy
The Sun is the primary source of life on Earth and it is also the largest and the most underutilized electrical power plant we will ever have. Barely one-tenth of all the energy we consume on Earth comes from solar, wind, and water power that is to say from renewable resources, the rest of our energy comes from inside the Earth from fossil fuels such as oil, coal, and natural gas. The problem is that the fossil fuels are a limited commodity and additionally they are a major contributor to global warming. Today yet the solar cells cannot compete with fossil fuels but researchers are working to develop a new type of solar cell that would change the way we get electricity forever. Their goal is to spread solar electricity over the world by producing cheap, Environment-Friendly Solar Cells and sustainable that they can be used all over the globe in a much larger fraction than what we see today.
The key is to make solar cells cheaper only then can they begin to compete with energy sources. There is no way to figure out in advance exactly how the solar cell should be built. Researchers have to find the right way by trial and error. All solar cells consist of two contact plates and a certain material in the middle, Silicon is more commonly used for this. It is this material in the middle the heart of the solar cell that absorbs the energy from the Sun and gives off electricity. In recent years, extremely thin solar cells have come, thanks to the use of new materials. The problem is that the materials used thus far are very rare and very expensive. A team of scientists is using more readily available and non-hazardous materials such as copper and zinc which makes the solar cells more sustainable and environmentally friendly.
After creating a solar cell in the clean room it is time to test how well it works in the laboratory. The goal is to constantly improve efficiency that is how much of the sunlight gets converted into electricity. But the measurement itself doesn’t work every time. So far the environmental friendly thin film solar cells have managed to convert nearly one-tenth of the Sun’s energy into electricity but to really succeed they will have to double this number. In the beginning, solar cells were really seen as a niche technology and were never going to be used on a large scale and now no one doubts that solar cells can contribute. This beginning of the revolution is transforming the energy sector and is just a start of something very big happening. With this research, the Earth’s surface will no longer be depleted for power; we will instead harness the power of the Sun.
