Many households are considering of converting their home energy to be solar powered for the purpose of cutting down their electricity bills while saving our planet with this environmental friendly power source. But, not many are taking their action to make the real conversion to a solar-powered home because they are still doubt on the [...]

Offering a view of the garden and an adjacent field, it looks like any other window. But this window offers an additional feature: it also produces electricity. The facades of the house, too, harness solar energy to supply the occupants with electrical power. This is what the domestic power supply of the future could look [...]

Sunflowers track the sun as it moves from east to west. But people usually have to convert sunlight into electricity or heat to put its power to use.
Now, a team of University of Florida chemists is the latest to report a new mechanism to transform light straight into motion – albeit at a very, very, [...]

Solar electricity has a bright future: It is renewable and available in unlimited quantities, and it does not produce any gases detrimental to the climate. Its only drawback right now is the price: the electric power currently being produced by solar cells in northern Europe must be subsidised if it is to compete against the [...]

A concentration solar power module that produces heat, cold and electricity and that can be integrated to facades or building roofs constitutes the new patent obtained by the University of Lleida.
This system has been developed by Daniel Chemisana, member of the research group in Agrometeorology and Energy for Environment, leaded by UdL lecturers Manel Ibáñez [...]

A research team from Northeastern University and the National Institute of Standards and Technology (NIST) has discovered, serendipitously, that a residue of a process used to build arrays of titania nanotubes-a residue that wasn’t even noticed before this-plays an important role in improving the performance of the nanotubes in solar cells that produce hydrogen gas [...]

Solar cells are usually made of silicon coated with a thin layer of silicon nitrate. This silicon nitrate works as an anti-reflective agent to boost cell efficiency. But the catch is these types of cells are costly to produce. This anti-reflective layer deposition happens in vacuum and creating vacuum like situation doesn’t come cheap!
Efforts are [...]

Scientists are continuously improving the existing solar cells. Now they are taking the help of computer simulations and real lab testing. A group of physicists and engineers at MIT have discovered new methods to make the existing solar cells more efficient by 50%. Currently the most efficient solar cell gives 45% output and is extremely [...]
