Mobility is a key parameter for semiconductor performance and relates to how quickly and easily electrons can move inside a substance. Researchers have achieved the highest mobility among thin films of tin dioxide ever reported. This high mobility could allow engineers to create thin and even transparent tin dioxide semiconductors for use in next-generation LED lights, … [Read more...] about A clear semiconductor based on tin could improve solar power generation
Microwaves power new technology for batteries, energy
New battery technology involving microwaves may provide an avenue for renewable energy conversion and storage. Purdue University researchers created a technique to turn waste polyethylene terephthalate, one of the most recyclable polymers, into components of batteries. "We use an ultrafast microwave irradiation process to turn PET, or polyethylene terephthalate, flakes into … [Read more...] about Microwaves power new technology for batteries, energy
Carbon dioxide sensor can lower energy use, reduce utility costs
Walk in a room, the light goes on. Most people are familiar with the motion sensors that detect activity and then turn on the lights. Purdue University researchers are turning to similar technologies to help manage climate control and indoor air quality. They have developed a sensor to help control and cut down on energy consumption through heating and ventilation systems, … [Read more...] about Carbon dioxide sensor can lower energy use, reduce utility costs
New scavenger technology allows robots to ‘eat’ metal for energy
New research is bridging the gap between batteries and energy harvesters like solar panels. Their 'metal-air scavenger' gets the best of both worlds. … [Read more...] about New scavenger technology allows robots to ‘eat’ metal for energy
Advancing high temperature electrolysis: Splitting water to store energy as hydrogen
Recently, researchers developed a new electrode material for an electrochemical cell that can efficiently convert excess electricity and water into hydrogen. When demand for electricity increases, the electrochemical cell is reversible, converting hydrogen back into electricity for the grid. The hydrogen could also be used as fuel for heat, vehicles or other applications. … [Read more...] about Advancing high temperature electrolysis: Splitting water to store energy as hydrogen
