Solar Cells May Get A Major Improvement
September 1, 2021 | Leave a Comment
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 […]

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 […]

2D Perovskites May Make Better LEDs and Solar Cells
April 15, 2021 | 1 Comment
Open Image…Save ImageOpen Image (using #TmpD/ia)… University of Surrey engineers’ innovative analysis of two-dimensional (2D) materials could boost the development of next-generation solar cells and LEDs. Three-dimensional perovskites have proved themselves remarkably successful materials for LED devices and solar panels in the past decade. One key issue with these materials, however, is their stability, with device performance decreasing quicker than […]

Los Alamos National Laboratory researchers have developed new quantum dot solar cells that match the efficiency of existing quantum-dot based devices, but without lead or other toxic elements relied on by most solar cells of this type. Victor Klimov, a physicist specializing in semiconductor nanocrystals at Los Alamos and lead author of the report featured […]

A Safer Lead Free Perovskite Found
May 12, 2020 | Leave a Comment
A Rensselaer Polytechnic Institute team of engineers, material scientists, and physicists have demonstrated how a new material – a lead-free chalcogenide perovskite – that hadn’t previously been considered for use in solar cells could provide a safer and more effective option than others that are commonly considered. A widespread transition to solar energy will depend […]
