SCIENTISTS DEVELOP SAFER LEAD-BASED PEROVSKITE SOLAR CELL STRUCTURE

SCIENTISTS DEVELOP SAFER LEAD-BASED PEROVSKITE SOLAR CELL STRUCTURE

Leave a Comment / Electronics News Updates / By

Researchers at Northern Illinois University and the U.S. Department of Energy’s (DOE) National Renewable Energy Laboratory (NREL) in Golden, Colorado, reported in the journal Nature on a potential breakthrough in the development of hybrid perovskite solar cells. Considered rising stars in the field of solar energy, perovskite solar cells convert light into electricity. They’re potentially cheaper and simpler to produce than …

At any given moment, the Earth’s atmosphere is showered with high-energy cosmic rays that have been blasted from supernovae and other astrophysical phenomena far beyond the Solar System. When cosmic rays collide with the Earth’s atmosphere, they decay into muons — charged particles that are slightly heavier than an electron. Muons last only fractions of …

Bismuth Oxyiodide (BiOI)—A Non-toxic Alternative To Solar Cells

Bismuth Oxyiodide (BiOI)—A Non-toxic Alternative To Solar Cells

Leave a Comment / Electronics News Updates / By

Bismuth is considered as a “green-element” and bismuth-based compounds are gaining attention as potentially non-toxic and defect-tolerant solar absorbers. The researchers of the University of Cambridge and the United States developed theoretical and experimental methods to show that bismuth, which sits next to lead (Pb) on the periodic table, can be used to make inexpensive solar cells. …

Carrageenan, a seaweed derivative, can stabilize lithium-sulfur batteries surprisingly

Carrageenan, a seaweed derivative, can stabilize lithium-sulfur batteries surprisingly

Leave a Comment / Electronics News Updates / By

Lithium-sulfur batteries are suitable for both vehicle and grid applications as they are ultra-cheap, high-energy devices. Sulfur is a very low-cost material and the energy capacity is much higher than that of lithium-ion. So, lithium-sulfur is one chemistry that can possibly meet the demand for energy storage at a cheap price. However, the serious problem is, lithium-sulfur …
