Wireless power transfer enhanced by metamaterials
Physicists design zero-friction quantum engine
Non-volatile memory improves energy efficiency by two orders of magnitude
Study explains how Maxwell's demon uses mutual information to extract work
Graphene layer could quadruple rate of condensation heat transfer in generating plants
Most of the world's electricity-producing power plants—whether powered by coal, natural gas, or nuclear fission—make electricity by generating steam that turns a turbine. That steam then is condensed ...
Researchers develop method of fabricating perovskite solar cells that is more efficient, costs less
Festo has BionicANTs communicating by the rules for tasks
Perovskite solar cell reaches record efficiency
Hybrid materials could smash the solar efficiency ceiling
(Phys.org) —A new method for transferring energy from organic to inorganic semiconductors could boost the efficiency of widely used inorganic solar cells.
Researchers use liquid inks to create better solar cells
(Phys.org) —The basic function of solar cells is to harvest sunlight and turn it into electricity. Thus, it is critically important that the film that collects the light on the surface of the cell is designed ...
A promising light source for optoelectronic chips can be tuned to different frequencies
Chips that use light, rather than electricity, to move data would consume much less power—and energy efficiency is a growing concern as chips' transistor counts rise.
LEDs made from 'wonder material' perovskite
(Phys.org) —Colourful LEDs made from a material known as perovskite could lead to LED displays which are both cheaper and easier to manufacture in future.
Self-cooling solar cells boost power, last longer
Scientists may have overcome one of the major hurdles in developing high-efficiency, long-lasting solar cells—keeping them cool, even in the blistering heat of the noonday Sun.
