Information about Carbon-based Solar Cells:

Solar Panels:

Solar panels require silicon for inclusion of light. Silicon doesn’t come inexpensive. This cost-factor is avoiding people from using solar energy on a large scale. Scientists utilize another substance i.e. ruthenium for solar cells. Ruthenium can is despicable than silicon but ruthenium is a rare metal on Earth. It is as uncommon as platinum. Naturally it can’t be available for mass production. Contrast to silicon, carbon is cheap and plentiful. The graphene, another structure of carbon, is capable of absorbing an extensive range of light frequencies.

Carbon based Solar Cell 

Graphene is a single sheet of carbon, one atom substantial. Graphene has prospective potential to be utilized as a successful, a smaller amount toxic and cheaper than other substitutes for solar cells. Chemists at Indiana University Bloomington are endeavoring to come about with a improved alternative than silicon. If successful, this can be a path breaking innovation.

Individuals Keen Interests:

Other people also obtain this proposal of using carbon sheets for solar power. But they meet some obstacles. They used the graphene form of carbon for solar cells. Grephene is similar to graphite used in pencil lead. Graphene absorbs a wide range of light frequencies. Scientists have established and found large sheets of graphene to be also impossible to work with. Large sheets are steamy and get attached with other sheets. Now Indiana University Bloomington researchers studied and are attempt to deal with this difficulty. They are trying to develop non-sticky graphene sheets that are steady.

They are putting their hard work on “attaching a semi-rigid, semi-flexible, three-dimensional side group to the sides of the graphene.” They know how to obtain energy from carbon. Now chemists from Indiana University Bloomington are graduating to the next logical step i.e. conversion of that energy into electricity. If the whole thing will turn out okay then carbon can be a substitute to costly silicon and ruthenium, which is as unusual as platinum.

Experts Endeavors:

Chemists and engineers carry on on trying to work out a solution for the stickiness of graphene. They developed numerous techniques for keeping single graphene sheets separate. Until now the most efficient and effective solution prior to the Indiana University Bloomington scientists’ experiment has been breaking up graphite (top-down) into sheets and enfold polymers around them. But this technique has its own drawback. Those graphene sheets are excessively large for light absorption for solar cells. Indiana University chemists devised an entirely new technique for carbon sheets. They utilized a 3-D bramble patch between the carbon sheets. This method assists the scientists to soften and dissolve sheets containing as many as 168 carbon atoms.

They are flourishing in making the graphene sheets from smaller molecules (bottom-up) so that they are homogeneous in size. Till now, it is the major stable graphene sheet ever made with the bottom-up advance. Chemist Liang-shi Li, who led the study, inform us, “Our interest stems from wanting to find an alternative, readily available material that can efficiently absorb sunlight. At the moment the most common materials for absorbing light in solar cells are silicon and compounds containing ruthenium. Each has disadvantages.”

Professional Views:

Li is of the view, “Harvesting energy from the sun is a prerequisite step. How to turn the energy into electricity is the next. We think we have a good start.” Other affiliates of the development group are Ph D students Xin Yan and Xiao Cui and postdoctoral fellow Binsong Li. This project is funded by the National Science Foundation and the American Chemical Society Petroleum Research Fund.
