Wood Floors Can Be Engineered to Produce Electrical Current
October 7, 2021 | Leave a Comment
Researchers from Switzerland are tapping into an unexpected energy source right under our feet – wood flooring. Their nanogenerator has been presented in the journal Matter. The nanogenerator enables wood to generate energy from our footfalls. The team also improved the wood used in the their nanogenerator with a combination of a silicone coating and […]

Big Photovoltaic Boost Found For Ferroelectric Solar Cells
September 30, 2021 | 1 Comment
Martin-Luther-Universität Halle-Wittenberg found the photovoltaic effect of ferroelectric crystals can be increased by a factor of 1,000 if three different materials are arranged periodically in a lattice. Researchers achieved this by creating crystalline layers of barium titanate, strontium titanate and calcium titanate which they alternately placed on top of one another. These findings could significantly […]

Better Internal Electrical Connections – Better Solar Cells
August 11, 2021 | Leave a Comment
University of Utah researchers identified crucial electrical noise signals in solar cells that are completely invisible to conventional noise-measuring methods. They were also able to pinpoint the likely physical processes causing the noise, which often results in a loss of energy and lower efficiency. The physicists used cross-correlation noise spectroscopy to measure miniscule fluctuations in […]
