Ultrathin organic solar cell: Both efficient and durable

Scientists from the RIKEN Cluster for Pioneering Research and RIKEN Center for Emergent Matter Science have succeeded, in collaboration with international partners, in creating an ultrathin organic solar cell that is both highly efficient and durable. Using a simple post-annealing process, they created a flexible organic cell that degrades by less than 5 percent over 3,000 hours in atmospheric conditions

Perovskite Solar Cells Made of Peppermint Oil and Walnut Aroma Food Additives, Preventing Lead Leakage

Solar energy that reaches the Earth is about 125 million gigawatt (Gw). When this solar energy generated for a year is converted into oil, it is 100 trillion ton which is ten thousand times more than the amount of oil energy the world uses in a year. So, it is no surprising when one of the coffee commercial ads said,

New type of indoor solar cells for smart connected devices

In a future where most things in our everyday life are connected through the internet, devices and sensors will need to run without wires or batteries. In a new article in Chemical Science, researchers from Uppsala University present a new type of dye-sensitised solar cells that harvest light from indoor lamps. The Internet of Things, or IoT, refers to a

Scientists to develop safer lead-based perovskite solar cell

Researchers at Northern Illinois University and the U.S. Department of Energy’s (DOE) National Renewable Energy Laboratory (NREL) in Golden, Colorado, are reporting today (Feb. 19) 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

Researchers to advance solar material production

A Washington State University team has developed a more efficient, safer, and cost-effective way to produce cadmium telluride (CdTe) material for solar cells or other applications, a discovery that could advance the solar industry and make it more competitive. The researchers showed they could rapidly grow a large amount of high-purity CdTe material — a more than kilogram-sized crystal in

Flexible thinking on silicon solar cells for wearable electronics or flexible robot skin

Flexible thinking on silicon solar cells from KAUST Video on Vimeo. Combining silicon with a highly elastic polymer backing produces solar cells that have record-breaking stretchability and high efficiency. © 2019 KAUST Crystalline silicon solar panels could be just as effective when incorporated into stretchy wearable electronics or flexible robot skin as they are when used as rigid rooftop panels.

In breakthrough method of creating solar material, scientists prove the impossible really isn’t

Scientists at the National Renewable Energy Laboratory (NREL) achieved a technological breakthrough for solar cells previously thought impossible. The scientists successfully integrated an aluminum source into their hydride vapor phase epitaxy (HVPE) reactor, then demonstrated the growth of the semiconductors aluminum indium phosphide (AlInP) and aluminum gallium indium phosphide (AlGaInP) for the first time by this technique. “There’s a decent
