Renewable energy is the cleanest and inexhaustible source of energy. They are a great alternative to fossil fuels. Renewable energy doesn't emit any greenhouse gases in the environment. They are environment-friendly and help us tackle the most important concern of the 21st Century - Climate Change.
Solar is one of the most important forms of renewable energy. Sun is an inexhaustible source of energy and solar cells help capture that clean energy for both commercial and domestic purposes. Despite all these advantages, Solar cells are not efficient when it comes to producing energy during rainy seasons. Since the input energy gets reduced, solar cells become practically useless when rain clouds are overhead.
Scientists from the University of Soochow, China have overcome the design flaw of solar cells by allowing them to generate energy both in the sunny and rainy season. This technology holds the potential of revolutionizing renewable energy completely.
The key part of this new Hybrid solar technology is the triboelectric nanogenerator or TENG. A device capable of producing an electric charge from the friction of two materials rubbing together.
These new hybrid solar cells works using a material called Graphene. It has the ability to produce energy from raindrops.
Like any other solar panel, these hybrid solar cells also generate electricity during a normal sunny day using the current technology, but when cloud gathers and raindrop falls, this solar panels system switch to its graphene system. Graphene, in its liquid form, can produce electricity due to the presence of delocalized electrons that help us create a pseudocapacitor framework. This pseudo framework helps us generate electricity.
