Working On Solar Cells That Will Print Like Newspaper

Investing in solar power still has a long enough economic break-even period to discourage more widespread investment. Creating less expensive and more efficient soalr panels is a key aspectof making solar power more universal.

Alternative Energy News reports:

"It is believed that solar cells could soon be produced more cheaply using nanoparticle “inks”. These nanoparticles can help in printing solar cells like newspaper or painted onto the sides of buildings or rooftops to absorb electricity-producing sunlight. Brian Korgel along with his team is working on this low-cost, nanomaterial solution that can replace the current photovoltaics. Brian Korgel is a chemical engineer at University of Texas at Austin. He is quite hopeful that his new technique coupled with different manufacturing processes will lower the price of solar cells to one tenth

Korgel is utilizing the light-absorbing nanomaterials. Their specialty is that they are 10,000 times thinner than a strand of hair. Their microscopic size makes it possible to attain higher-efficiency devices. The inks could be printed on a roll-to-roll printing process. They can use a plastic substrate or stainless steel for printing. It seems that this type of ink could be used to paint a rooftop or building and it doesn’t look like a tall claim." See full article.
