Silicon sheets self-assemble into spheres to capture more light. Thin-Film Solar with High Efficiency Solexant is printing inorganic solar cells with nanomaterials. Nano Ink Boost for Silicon Solar Inkjet-printed silicon increases solar-cell efficiency. A Liquid Design for Cheaper Fuel Cells A platinum-free liquid cathode could cut fuel-cell costs by 40 percent. Flexible carbon-nanotube supercapacitors could give more power to cell phones and other electronics. Harnessing Direct Solar Power for Propulsion Tiny boats made of nanomaterials are powered directly by sunlight. A Hybrid Nano-Energy Harvester The device harnesses both sunlight and mechanical energy. A Catalyst for Cheaper Fuel Cells The material could replace platinum in hydrogen vehicles. Energy-Saving Helicopter Blades NASA researchers are using smart materials to improve helicopter performance. A new fuel cell uses a cheap nickel catalyst. A new type of silicon promises cheaper, more-sensitive light detectors. Thin but efficient solar cells use one-tenth the silicon of conventional cells. Nanoflowers Improve Ultracapacitors A novel design could boost energy storage. Materials that change temperature in response to electric fields could keep computers--and kitchen fridges--cool. [1]
