Scientists have developed completely carbon-producing solar cells that are cheaper than traditional solar cells. New solar cells, which have the flexibility to cover surfaces such as windows, may replace traditional solar panels in the future if desired performance is achieved. Researchers at Stanford University, USA, have produced the world's first full-carbon solar cell. New solar panels may be an alternative to expensive photovoltaic materials, the researchers said.
Carbon-related R&D studies are continuing rapidly all over the world. Both the development of material science and the use of carbon economically are of interest to the world of science. Carbon is a product with the potential to be used in a large area, whether in composite production or energy storage.

"Carbon is capable of high performance at low cost. For the first time, we have produced a solar cell that carries carbon properties and works," he said. Bao pointed out that silicon solar panels are not bent, noting that the new technology solar panels are in a thin film form that can cover certain surfaces.
From there, bao said, flexible solar panels can be produced to cover surfaces such as windows in the future, so that large solar panels covering the roofs of buildings can be history.
The carbon solar cell replaces existing cells that use oxide electrodes with graphene (the main ingredient of carbon is the single atomic size of graphite) and carbon nanotubes. Oxide electrodes are running out at a greater rate as demand for solar panels increases, and so does the price. The new solar cells also contain sphere-shaped C60 carbon molecules called 'buckyballs'.
Michael Vosgueritchian, another scientist involved in the study, said: "The solar cell we developed in our laboratories is made manufactured from carbon from top to end. Similar studies have been announced in the past, but only the middle layer of the solar cells in question was carbon, electrodes were not included," he said.
"The solar cell captures almost all infrared wavelengths, but in the laboratory environment the effeth rate is less than 1 percent," Vosgueritchian commented. Bao said that a longer period of time is needed to improve the performance of solar cells, and that they will try new techniques and materials in this context.
