Tag: solar cellsWrapping Solar Cells around an Optical Fiber Dye-sensitized cells get a double boost from nanowires and optical fiber. The low-cost cells make their debut on electronics-charging bags. Cyrus Wadia is using abundant materials to grow nanocrystals for cheaper photovoltaics. Nanopatterns Improve Thin-Film Solar Cells Thin-film silicon solar cells are more efficient with tiny holes in the back electrical contact. More Efficient, and Cheaper, Solar Cells New manufacturing techniques could cut solar power costs by 20 percent. Researchers make cells with near-perfect internal efficiency. A Hybrid Nano-Energy Harvester The device harnesses both sunlight and mechanical energy. Cheap, Durable Nonsilicon Solar Cells An advanced dye boosts the efficiency of dye-sensitized solar cells. A new way to convert heat into electricity could lead to more efficient solar power. Efficient Thin-Film Solar Cells The first prototype cell to use photonic crystals looks promising. Making Silicon Less Reflective A silicon coating could boost the efficiency of solar cells. Improved dyes and electrolytes could make the Grätzel solar-cell design more practical. A new type of silicon promises cheaper, more-sensitive light detectors. Mass Production of Plastic Solar Cells A novel photovoltaic technology moves into large-scale production. |
