  • Detecting defects in solar cells

    Solar panels, or photovoltaic (PV) modules, are being rapidly deployed across the world as costs fall and the need for sustainable, low-carbon energy grows. Being able to effectively characterise PV cells is a key factor in quality control during manufacturing and understanding their long-term behaviour. NPL researchers, Simon Hall, Matt Cashmore and John Blackburn, have developed a new technique ...

  • Boosting the power of solar cells

    New ways of squeezing out greater efficiency from solar photovoltaic cells are emerging from computer simulations and lab tests conducted by a team of physicists and engineers at MIT. Using computer modeling and a variety of advanced chip-manufacturing techniques, they have applied an antireflection coating to the front, and a novel combination of multi-layered reflective coatings and a tightly ...

  • Solar cell, heal thyself

    Plants are good at doing what scientists and engineers have been struggling to do for decades: converting sunlight into stored energy, and doing so reliably day after day, year after year. Now some MIT scientists have succeeded in mimicking a key aspect of that process. One of the problems with harvesting sunlight is that the sun's rays can be highly destructive to many materials. Sunlight leads ...

  • Recycling old batteries into solar cells

    Original story at MIT News This could be a classic win-win solution: A system proposed by researchers at MIT recycles materials from discarded car batteries — a potential source of lead pollution — into new, long-lasting solar panels that provide emissions-free power. The system is described in a ...

  • Solar cells linked to greenhouse gases

    Solar cells do not offset greenhouse gases or curb fossil fuel use in the United States according to a new book published by the University of Nebraska. Written by University of California - Berkeley visiting scholar Ozzie Zehner, the book (Green Illusions: The Dirty Secrets of Clean Energy and the Future of Environmentalism), explains how the solar industry has grown to become one of the leading ...

  • Dye Sensitized Solar Cells Market

    Although initial products are aimed towards indoor and portable applications, starting out with chargers and solar bags with wireless solar keyboards demonstrated more recently, the end game for DSSCs is the ability to have these largely inexpensive solar cells incorporated into much bigger installations. For that purpose, development work is being undertaken in order to produce prototypes and ...


  • Miniature Solar Cells Market Potential

    Miniature Solar Cells Market PotentialSolar power is the technology of obtaining usable energy from the light of the Sun. Solar energy has been used in many traditional technologies for centuries and has come into widespread use where other power supplies are absent, such as in remote locations and in space. ( ...


  • MIT unveils first solar cell printed on paper

    When most people think of solar cells they picture the rigid glass panels that dot rooftops around the world. But the solar cells of the future will be much more adaptable, with researchers already succeeding in creating highly absorbing flexible solar cells that can be printed on plastic. Now researchers at MIT have gone one step further with the development of the first solar cell printed on ...
