Berkeley Lab researchers another step closer to reaping fuel from sunlight In the quest to realize artificial photosynthesis to convert sunlight, water, and carbon dioxide into fuel – just as plants do – researchers need to not only identify materials … Continue reading →
Perovskite solar cells are a promising new low-cost photovoltaic technology, but most contain toxic lead; a team led by Brown researchers has introduced solar cells with a new titanium-perovskite material that gets the lead out.
Why are efficient and affordable solar cells so highly coveted? Volume. The amount of solar energy lighting up Earth’s land mass every year is nearly 3,000 times the total amount of annual human energy use. But to compete with energy … Continue reading →
Researchers from North Carolina State University have created flower-like structures out of germanium sulfide (GeS) – a semiconductor material – that have extremely thin petals with an enormous surface area. The GeS flower holds promise for next-generation energy storage devices … Continue reading →
Berkeley Lab scientists and their colleagues have successfully probed the effects of light at the atomic scale by mixing x-ray and optical light waves at the Linac Coherent Light Source Light changes matter in ways that shape our world. Photons … Continue reading →
Innovations by a team of Yale University researchers could lead to improvements in basic solar power technology that result in lower-cost, higher-efficiency photovoltaic systems. Photovoltaics (PV) directly convert sunlight into electricity. PV systems can be arrayed on rooftops to generate … Continue reading →
