SciencePhysicsScientists Discover Hidden Information in 140-Year-Old Fundamental Physics Concept
Physicists have uncovered a way to access physical information that had been hidden to science for 140 years, according to a recent paper. Back in 1879, physicist Edwin Hall discovered that electrical currents bend when placed in a magnetic field, producing a voltage and a new electrical field perpendicular to the current. Scientists have since … Continued

This Cheap, New Solar Cell Doubles As a Battery
Solar power has an efficiency problem. When the electrons move from the solar panel to the battery that stores them, about 20 percent of the energy is lost. But now, thanks to new type of solar cell, nearly 100 percent of the energy is stored. That’s because the solar cell itself is the battery. Researchers … Continued

Tech NewsMIT Explains How To Turn an Old Car Battery Into a Working Solar Cell
There are over 1 billion cars in the world, and the vast majority of them use batteries made from lead. As lithium batteries replace these old timers, eventually there may be many of the lead suckers sitting in landfills. Which is why MIT wanted to find a way to reuse them—by turning them into a … Continued

New Connectors Let Solar Cells Withstand the Power of 70,000 Suns
The power of 1,000 suns? Pfft. That ain’t nuthin’. A recent breakthrough in solar panel connections has allowed scientists to create arrays of solar cells that can stand strong under the blazing glare of 70,000 suns. Not that they’d ever have to, but still. Stacked solar cells—which are exactly what they sound like—are some of … Continued

Tiny Solar Cell Converts An Amazing 44.4% of Sunlight To Electricity
Today’s solar panels convert about 20% of the Sun’s energy to electricity—which is good, but solar power would be much cheaper to use if the solar cells converted more of our star’s energy. Sharp has just made a huge step in this direction, with a new cell that converts a record 44.4% of sunlight into … Continued

New technology that captures “exciton” particles could replace today’s solar cells
Even the most efficient solar cell loses a lot of energy in the form of wasted heat. But the electron-like particles that photons emit as they enter the cells could be turned into electrical energy, solving the heat loss problem. When photons, the particles of light, enter solar cells, they can create a quasiparticle known … Continued
