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 […]

Scientists at Martin-Luther-Universität Halle-Wittenberg (MLU) are boosting the photovoltaic effect in ferroelectric-paraelectric superlattices. The team is reporting 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. The researchers achieved this by creating crystalline layers of barium titanate, strontium titanate and […]

Nagoya Institute of Technology scientists combined two promising photocatalysts to obtain higher solar-to-hydrogen conversion efficiency and durability in a water splitting cell. Both industry and academia have been focusing heavily on hydrogen as a feasible clean alternative fuel. Hydrogen is practically inexhaustible and when reacted to generate energy, only produces water vapor. However, to realize […]

Open Image…Save ImageOpen Image (using #TmpD/ia)… Penn State researchers report that they have taken a step toward overcoming the challenge of inexpensive hydrogen production. They report to have taken the step by using supercomputers to find materials that could help accelerate hydrogen separation when water is exposed to light, a process called photocatalysis. Using solar energy to inexpensively harvest hydrogen […]

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 […]
