Mother Nature Network: A new technique could help keep dust off of solar cells, a major obstacle that reduces the efficiency of photovoltaic panels. The technique, developed by Sergey Biryukov, a researcher at the Ben-Gurion National Solar Energy Center, uses an electric field to charge dust and small particles before repelling them. At a recent demonstration, Biryukov poured a small amount of a dustlike powder onto an electrified solar cell. The dust was immediately thrown back prevented by the electric field from settling...

Norwegians trap sunlight with microbeads, produce solar cells that are 20 times thinner, cheaper

Researchers from the University of Oslo have used a bunch of "wonderful tricks" to produce silicon solar cells that are twenty times thinner than commercial solar cells. This breakthrough means that solar cells can be produced using 95% less silicon, reducing production costs considerably -- both increasing profits (which are almost nonexistent at the moment), and reducing the cost of solar power installations.
