Punching holes in opaque solar cells turns them transparent

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…

Making higher-energy light to fight cancer

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,…

New standard of reference for assessing solar forecast proposed

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…

Even short-lived solar panels can be economically viable

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.
