Withthe help of computer simulations and various advancedchip-manufacturing methods, a team of physicists and engineers at MIThave discovered new ways of getting greater efficiency from photovoltaic solar cells.
According to Lionel Kimerling, the projectmanager and Thomas Lord Professor of Materials Science and Engineering:"The simulated performance was remarkably better than any otherstructure, promising, for 2-micrometer-thick films, a 50 percentefficiency increase in conversion of sunlight to electricity. But what they have not figured out yet is how long that path has to beto ensure maximum absorption of electrons to produce the electriccurrent."
To evaluate its business potential, the projectwas selected by the MIT Deshpande Center for an "i-team" study.
The test was started by running thousands of computersimulations, testing variations of the thickness of the silicon, spacing of the lines, and the amount and thickness of reflective layerson the back.
. Withoutthose coatings the light would be reflected straight out of the cell.
Oneof the team members, Peter Bermel, a post-doctoral researcher in MIT’sphysics department explained that it is critical that any lightentering the layer should travel through a long path in the silicon.
Whileno single project is likely to minimize the cost of solar cells, thistype of innovation takes us one step closer to making solar power design competitive with fossil fuel and nuclear grid electricity.

Inthe experiment, the team applied an anti-reflective coating to thefront, and a innovative series of multi-layered reflective coatings anda defraction grating - a closely spaced array of lines - to the back ofultra-thin silicon films to increase the cells’ power by up to 50%.
According to Kimberling,if the solar business stays strong, we can expect this new technologyto be ready within the next three years.
Withthe help of the carefully designed layers on the back of each cell,light is bounced around longer inside the thin silicon film, allowingit more time to transfer its energy into an electric current."
Oncesimulations were complete, they were confirmed by actual lab-scaletests, where graduate student Lirong Zeng was given required to refinethe structure and make the silicon cell.
Thework done so far was just the first step toward manufacturing anaffordable, improved solar cell. Here itwas concluded that this thin film solar cell technology could provideconsiderable benefits in both manufacturing and electricity production,for uses ranging from remote off-grid to dedicated clean energy.
New solar power design research conducted at the Massachusetts Institute of Technology (MIT) could lead to higher powered, more affordable solar panels. Now all that is Home Appliance Metal Part needed is somefine-tuning through more simulations and lab tests, and more work onthe materials and manufacturing process. Bermel added that, "thepotential for savings is great, since the high-quality silicon crystalsubstrates used in conventional solar cells represent about half thecost, and the thin films in this version use only about 1 percent asmuch silicon. As predicted, the experimentwas a success and sparked considerable industry interest. These simulations were then Machining Part used to optimize efficiencyand power output
