Tag: solar cellsA New Way to Use the Sun's Energy Researchers have demonstrated a new mechanism for converting both sunlight and heat into electricity. Bumpy Coatings for Better Solar Cells A simple method applies nanoscale texturing over large areas. Nanopillars that Trap More Light The new design could lead to cheaper solar cells. "Light Pipes" Boost Organic Solar Efficiency A layer of optical fiber bristles doubles the performance of organic solar cells in tests. A Caltech group has created materials that could improve the efficiency of solar cells. Green LEDs for Efficient Lighting Solar-cell manufacturing techniques could yield LEDs that require 20 percent less energy. Silicon Microwires Could Have a Sunny Future New solar cells show gains in efficiency. Silicon sheets self-assemble into spheres to capture more light. 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. Superefficient Solar from Nanotubes Carbon nanotube photovoltaics can wring twice the charge from light. A rolling nanoimprint lithography stamp could be used to print components for displays and solar cells. A new polymer simplifies organic circuits. Higher-Performance Plastic Electronics A new way of printing organic electronics is more reliable and yields higher performance. Researchers make cells with near-perfect internal efficiency. |
