Researchers in Korea have found an effective and inexpensive strategy to transform solar cells from opaque to transparent. Existing transparent solar cells tend to have a reddish hue and lower efficiency, but by punching tiny holes on crystalline silicon wafers, it allows light through without coloring. The holes are then strategically spaced, so the human…
Researchers have achieved photon up-conversion, the emission of light with energy higher than the one that excites the material, using carefully designed structures containing silicon nanocrystals and specialized organic molecules. The accomplishment brings scientists one step closer to developing minimally invasive photodynamic treatments for cancer. The advance could also hasten new technologies for solar-energy conversion,…

Many of the most dramatic events in the solar system — the spectacle of the Northern Lights, the explosiveness of solar flares, and the destructive impact of geomagnetic storms that can disrupt communication and electrical grids on Earth — are driven in part by a common phenomenon: fast magnetic reconnection. In this process the magnetic…
Scientists have conducted an in-depth study on how carbon nanotubes with oxygen-containing groups can be used to greatly enhance the performance of perovskite solar cells. The newly discovered self-recrystallization ability of perovskite could lead to improvement of low-cost and efficient perovskite solar cells.

This year’s Nobel Prize in Physics is being awarded “for contributions to our understanding of the evolution of the universe and Earth’s place in the cosmos,” with one half to James Peebles “for theoretical discoveries in physical cosmology” and the other half jointly to Michel Mayor and Didier Queloz “for the discovery of an exoplanet…
Being able to accurately forecast how much solar energy reaches the surface of the Earth is key to guiding decisions for running solar power plants and new work looks to provide a standard of reference to the field. A researcher proposes an improved way to assess day-ahead solar forecasting, which combines two popular reference methods…
A new study shows that, contrary to widespread belief within the solar power industry, new kinds of solar cells and panels don’t necessarily have to last for 25 to 30 years in order to be economically viable in today’s market.
