Revolutionary Solar Power Design
New design of research on solar energy carried the Institute of Technology Massachusetts (MIT), could lead to a higher power, solar panels more affordable.
With the help of computer simulations and chip Advanced Various methods of manufacture, a team of physicists and engineers at MIT have found new ways to achieve greater efficiency of photovoltaic solar cells.
In the experiment, The team applied an anti-reflective coating on the front, and an innovative series of multi-layer reflective coating diffraction grating films – a series of spaced lines – to the rear units of thin silicon to increase the capacity of cells to 50%.
With the help of carefully designed layers in the back of each cell, the light was found around longer inside layer thin silicon allowing more time to transfer his energy into electrical current. Without those facing the light is reflected outwards Cell.
One member of the team, Peter Bermel, a postdoctoral researcher in the physics department at MIT, said it is essential that light must penetrate the layer travel through a long path in silicon. But they have not yet discovered is the time this path must be to ensure maximum absorption of electrons produces electric current.
The trial was initiated by the execution of thousands of computer simulations, evidence of variations in the thickness of silicon line spacing, and the amount and thickness of layers Reflecting on the back. These simulations were used to optimize efficiency and power.
According to Lionel Kimerling, director Project and Thomas Lord Professor of Materials Science and Engineering: "Simulation performance was significantly better than any other structure, with the promise, for 2-micron-thick films, a yield increase of 50 percent by converting sunlight into electricity. "
Once the simulations were complete, which were confirmed by the testing laboratory scale, where the graduate student Lirong Zeng has been taken to improve the structure and composition of the silicon cell. Predictably, the experiment was successful and has attracted considerable interest from industry.
The work so far is that the first step towards manufacture of affordable, improved solar cells. Now all that is needed is further adjusted by means of simulations and laboratory tests, and more work on materials and manufacturing processes.
According to Kimberling, if the solar energy company remains strong, we can expect that this new technology to be ready in the next three years. Bermel added, "the potential savings is important because the high quality glass substrates for silicon used in conventional solar cells account for about half the cost and use thin films in this version only 1 percent as silicon lot.
To assess their economic potential, the project has been selected by the Deshpande Center at MIT for an "I-Team study. It was concluded that cells of this thin film technology solar could provide significant benefits in both the manufacturing and electricity production, for applications ranging from remote off-grid dedicated to energy clean.
Although it is unlikely that one project to minimize the cost of solar cells, this kind of innovation takes us another step closer to the design of solar energy competitive with fossil fuels and nuclear electricity network.

Number of sunny days at Andover?
Hello, our school seeks to become more sustainable. So one of our ideas is the creation Solar panels. However, the sunny days of issues and questions is how many are produced in Andover, Massachusetts, in the 365-day cycle? Are there any sources? National? Local? Etc? THANK YOU! Go Green! : D
I found these data in Andover, but not a percentage of clear days.
