The Massachusetts Institute of Technology (MIT) recently carried out a demonstration of several technologies are still at the prototype stage that have been subsidized by the Italian company Eni, engaged in the oil business.
One of them has been a solar cell that has the thickness of a sheet of paper. During the exhibition, one of these cells was able to supply enough energy to power an LED display.
This technology is based on the use of multiple layers of solid material deposited on a substrate of paper, each has a different function from the absorption of light to transport the energy generated through the release of electrons to generate electricity. Power generation can be done, unlike other techniques, at low temperatures.
According to project managers, this technology could be ready for the market within five years. Its use can be extended to a large scope of projects, from its location on roofs, portable enclosures, windows, etc, and it is a non-rigid panels.
Electric vehicle with lithium batteries do not emit CO2, provided that electricity comes from renewables such as wind, solar photovoltaic and solar thermal or thermal. Wind turbines can supply electricity to electric vehicles, which in future will also serve to store and regulate the electricity intermittent wind energy sector.
