“No one wants to sit behind colored glass. These past efforts have yielded poor results because the energy production was low and the materials were highly colored, despite their transparent label. Many so-called ‘transparent solar cells’ in the past weren’t actually transparent because they only allowed a part of the light to pass through and they also casted a colorful shadow. A material that is considered “transparent”, by definition, enables all the light to pass through it and strike the back of the eye. That’s because photovoltaic solar cells generate energy by absorbing sunlight (photons), and transforming it into electricity (electrons). Scientifically, the term “transparent solar panel” or “see-through solar window” is something of an oxymoron. The Transparent Solar Panel: Somewhat of an Oxymoron The final result: see-through solar panels. The ever-increasing popularity of solar energy systems has fueled intense research. The magazine ads that the number of solar roofs has increased 70 percent every year, going from 4 states with animated residential solar markets, to 10 states. Despite their enormous size and unattractive appearance, solar panels are increasing in popularity.Īccording to a recent Fortune magazine report, the number of American residential solar energy panels has been quickly growing and expanding across multiple states. However, when people think about solar energy they generally imagine oversized, dark checkerboards sitting in endless fields or installed on rooftops. Solar energy is by no means a new concept. For many years, scientists have worked on a window coating that could capture the sun’s heat (or keep it outside) while letting the sun’s gentle rays enter. As a matter of fact, many architects and designers treat windows only to reduce the sun’s heat and glare. Neptune's average density is the greatest among all the gaseous planets, suggesting it has, proportionally, the largest core.Anyone who has sweltered in a south-facing room during torrid summer days knows just how much solar power can stream through a window. It is believed that the planet core is comprised of rock and nickel-iron alloy. The lower layer is made up of the liquid hydrogen which may become metallic just above the core. Below its clouds the gaseous atmosphere gets hotter and thickens to a fluid state. The atmosphere of Neptune consists of mainly hydrogen, helium, and methane, similar to Uranus. The planet's core is believed to be rock and nickel-iron alloy encompassed by an outer layer of extremely hot fluid comprised of water, ammonia, and methane. The planet's atmosphere has small amounts of methane. Uranus is gaseous in composition, mainly comprised of hydrogen and helium as in the case of Jupiter and Saturn. The planet's core is believed to be composed of rock and nickel-iron alloy. It is believed that the liquid hydrogen layer of Saturn is thicker than that of Jupiter, while the liquid metallic hydrogen layer may be thinner. Further down, as in the case of Jupiter, there is a layer of liquid metallic hydrogen. Beneath the clouds, Saturn's hydrogen atmosphere thickens to become a fluid, with no distinct surface separating gaseous hydrogen from liquid hydrogen. Suspended in Saturn's hydrogen-helium atmosphere, in descending order of altitude, a layer of ammonia clouds, a layer of ammonium hydrogen sulfide clouds, and a layer of water clouds. Saturn's mean density is only about two-thirds that of water. The planet core is believed to be comprised of iron-nickel alloy and materials with the composition of rock, etc., at a temperature estimated to exceed 20,000 degrees CelsiusĪs with Jupiter, Saturn is mainly composed of hydrogen and helium and is observed to be of surprisingly low density. The zone of liquid hydrogen extends to a depth where the pressure is so high that it is believed there is a layer of liquid metallic hydrogen at a pressure of 3 million bars. Beneath the cloud layers, the clear atmosphere is denser and warmer and slowly transforms from a gas to a liquid without a sharp boundary to mark the change. We see the cloud tops (beneath a transparent, mostly hydrogen upper atmosphere). In contrast to planetary bodies covered with a hard surface crust (the Earth, for example), there is no jovian surface. Jupiter's composition is mainly hydrogen and helium.
