just a shame that not smell of blueberry. Otherwise, organic solar cells as well as revolutionize the world of solar panels would help to cover the smell of smog in our cities. They can use as an active pigments made from berries and unlike normal solar panels on the market today have eliminated the silicon. It will cost less to produce them and then install it, but most take the form of flexible sheets or plates semi-transparent glass. Then tomorrow will be "stretched" over the buildings, tends to work as a cover for civil protection, to be part of the windows of a building or a crystal of a car. "Almost all the solar panels on the market is made up of silicon that return about 15% of solar energy they receive," says Thomas Brown, Anglo-Italian scientist who, together with Aldo Di Carlo, and Andrea Reale director Franco Giannini Pole for Organic Photovoltaic Lazio at the Department of Electronic Engineering, University of Rome Tor Vergata. "So to meet the needs of an average user need to install panels on large areas. But the real problem is the cost manufacturing and production problems that make the spread in the absence of government incentives. Not to mention that the price of high-purity silicon is not going to get considering the scarcity of supply. "But there is indeed an alternative, a way that the scientific community is investigating the early 90s to lower costs of both the production and installation. A technology capable of producing solar panels as a support using two layers of plastic or glass that contain within them a thin film of organic semiconductor material. With a cost estimated at less than half of a panel of silicon.
of such cells there are two types: hybrid (organic / inorganic) and the totally organic. At the base is used a process similar to photosynthesis, with a mixture of materials in which the pigment absorbs solar radiation and other components extract the charge to generate electricity. The problem, at least for now, is the efficiency and durability. "The fully organic solar cells reach a maximum efficiency of 4% in the lab," says Brown. "These hybrid instead are closer to a technological maturity, and then the commercial exploitation because they last longer and efficiency is about 10%. So much so that companies like Konarka Technologies, Dyesol, Aisin Seki, Hitachi, and Sharp are investing large resources in developing this area. " According to estimates in the next few years the efficiency will be further improved, including the cell completely organic, because the benefits are really a lot compared to solar panels today. "Just think of the applications," says Brown. "Since we rolled up and become easier to bring such a valuable resource in the event of natural disasters. And it is just one of many possible uses." In short, the future with regard to clean energy is in the body and for a time Italy will not go back. The first practical application? Ventotene island in 2008 when the first panels will be installed based on this new technology.
