Scientists develop printable solar panels

Researchers at New Jersey Institute of Technology have created cheap solar panels that can be painted or printed on flexible plastic sheets:
"The process is simple," said lead researcher and author Somenath Mitra, PhD, professor and acting chair of NJIT's Department of Chemistry and Environmental Sciences. "Someday homeowners will even be able to print sheets of these solar cells with inexpensive home-based inkjet printers. Consumers can then slap the finished product on a wall, roof or billboard to create their own power stations."

Harvesting energy directly from abundant solar radiation using solar cells is increasingly emerging as a major component of future global energy strategy, said Mitra. Yet, when it comes to harnessing renewable energy, challenges remain. Expensive, large-scale infrastructures such as wind mills or dams are necessary to drive renewable energy sources, such as wind or hydroelectric power plants. Purified silicon, also used for making computer chips, is a core material for fabricating conventional solar cells. However, the processing of a material such as purified silicon is beyond the reach of most consumers.

"Developing organic solar cells from polymers, however, is a cheap and potentially simpler alternative," said Mitra. "We foresee a great deal of interest in our work because solar cells can be inexpensively printed or simply painted on exterior building walls and/or roof tops. Imagine some day driving in your hybrid car with a solar panel painted on the roof, which is producing electricity to drive the engine. The opportunities are endless. "
