Nanosolar: Solar Power at a Lower Cost

Nanosolar: Solar Power In a market-friendly scenario, Nanosolar claims to be able to produce electricity at 5-6 cents/kilowatt hour almost as cheap as power from coal and at about one-third the cost of other solar power. Nanosolar claims: Nanosolar claims mass production of solar power will now become feasible with their differently manufactured solar panels. Conventional silicon-made solar panels have a stiff competitor from CIGS semiconductor printed solar panels – composed of copper, gallium, indium and selenium – which perform as good as conventional solar panels in lab conditions. An inexpensive printing process makes it ideal for mass production by an automated facility with robots and other hi-fi equipment.

Solar panels re-invented:
The low efficiency which haunted Nanosolar raising the cost of installation of solar-power arrays and which necessitated more solar panels has been addressed successfully by Nanosolar. The larger panels they are now using generate more power; with modifications that cut the cost, the larger panels generate 160 watts as against 70 watts by First Solar.

Power output:
According to Martin Roscheisen, Nanosolar’s CEO, in sunny locations, power plants with these panels could produce electricity at 5-6 cents per kilowatt hour. Mr. Roscheisen claimed even the 16.4 % energy conversion in sunlight as against 20% energy conversion in the lab and only 11% of that energy into electricity by Nanosolar is high enough compared to conventional solar panels.

Raring to go!
Based at Germany and enjoying a huge market thanks to government’s incentives for the solar cells made of CIGS semiconductor, Nanosolar is ready to storm the market with producing solar cells twice as fast as the conventional solar-panel factories. He is ready to give First Solar a run for its money.

Not bankable?
But the claimed low costs are attainable only at close-to-capacity operation level which is at best a distant possibility. Because despite all improvements, under the current economic scenario, Nanosolar is finding it tough to find banks willing to back power plants which may be ready to use their solar panels. Now the panels are not yet “bankable;” but Nanosolar is hoping for a better future.

MIT Researchers Print a Solar Cell on Paper

Solar Cell on Paper We love the idea of clean and green fuel. But they come with certain disadvantages. First one is they are heavy on pocket of a commoner. Second disadvantage is their power conversion rate is quite low. Last one is you need storage space to save all the power converted by a clean and green technology. Now MIT researchers are coming out of solar cells printed on paper. Though the technology still has to wait for years before it can be converted into a commercially viable entity but it’s an interesting development.

Scientists at the Massachusetts Institute of Technology have effectively coated paper with a solar cell. It is a part of a suite of research projects aimed at energy breakthroughs.

Susan Hockfield, MIT’s president, and Paolo Scaroni, CEO of Italian oil company Eni, formally dedicated the Eni-MIT Solar Frontiers Research Center. Eni financed the research project by investing $5 million into the center. This project is also financed by National Science Foundation. They are granting a fund of $2 million.

The MIT people took inspiration from the inkjet printer. They molded the solar paper panels on the similar lines. They used organic semi conductor material. The technique will be quite helpful in lowering the weight of solar panels. “If you could use a staple gun to install a solar panel, there could be a lot of value,” Vladimir Bulovic, director of the National Science Foundation, said.

MIT researchers utilized carbon-based dyes. The efficiency of paper based solar cells is not great, at around 1.5% to 2%. But Vladimir Bulovic says that one can use any material if it can be deposited at room temperature. He further says, “Absolutely, the trick was coming up with ways to use paper,” he said.

Prof. Karen Gleason is the head of the MIT research team. She has submitted a paper for scientific review but it has yet to be published. MIT and Eni have confirmed that this is the first time a solar cell has been printed on paper.

During the press conference, Paolo Scaroni said that Eni is funding the center because the company understands that hydrocarbons will eventually run out and believes that solar can be a replacement, although the currently available technology isn’t sufficient enough.

Paolo Scaroni said, “We are not very active (in alternative energy) today because we don’t believe today’s technologies are the answer of our problems.”
