New solar forecasting model performs best
29 Jun 2020 at 9:02am
A new mathematical model for predicting variations in solar irradiance has been developed. It may help to promote more efficient use of electricity from solar energy. In tests of various data models, the model proved capable of making highly reliable forecasts, and emerged as the best for this purpose in some respects.
Why are plants green?
25 Jun 2020 at 11:49am
When sunlight shining on a leaf changes rapidly, plants must protect themselves from the ensuing sudden surges of solar energy. To cope with these changes, photosynthetic organisms have developed numerous tactics. Scientists have been unable, however, to identify the underlying design principle. A physicist has now constructed a model that reproduces a general feature of photosynthetic light harvesting, observed across many photosynthetic organisms.

Double-sided solar panels that follow the sun prove most cost effective
3 Jun 2020 at 10:25am
Solar power systems with double-sided (bifacial) solar panels -- which collect sunlight from two sides instead of one -- and single-axis tracking technology that tilts the panels so they can follow the sun are the most cost effective to date, researchers report. They determined that this combination of technologies produces almost 35% more energy, on average, than immobile single-panel photovoltaic systems, while reducing the cost of electricity by an average of 16%.
Precision spray coating could enable solar cells with better performance and ...
3 Jun 2020 at 10:25am
Although perovskites are a promising alternative to the silicon used to make most of today's solar cells, new manufacturing processes are needed to make them practical for commercial production. To help fill this gap, researchers have developed a new precision spray-coating method that enables more complex perovskite solar cell designs and could be scaled up for mass production.
Solar hydrogen production: Splitting water with UV is now at almost 100% quan...
3 Jun 2020 at 7:45am
Scientists have successfully split water into hydrogen and oxygen using light and meticulously designed catalysts, and they did so at the maximum efficiency meaning there was almost no loss and undesired side reactions. This latest breakthrough in solar hydrogen production makes the likelihood of scalable, economically viable hydrogen production more than likely, paving the way for humanity to make the switch to clean energy.
