Solar energy on a cloudy day - it is possible!

The Department of Energy in the United States has launched a study to devise models available solar cells able to accumulate solar energy in order to use its position in the rainy and cloudy days.

Experts from the University of California have found quite a cost effective way to solve the problem, and now many businesses and individuals will use their quiet solar panels, regardless of weather conditions. To optimize the structure of breathing batteries iron plates was necessary to add a small portion of bismuth sulfide, and the device is now able to store more energy from the sun for a longer period of time.

This has reduced the percentage of energy losses from 50% in conventional batteries to 4% in the new models with the addition of bismuth. The invention of the more attractive it uses materials which are anything but rare on the planet — this iron and air. In addition to lighting the home, the new battery could fuel major appliances in the house during the day.

The invention is of interest to the public, not to mention the scientific community and the leadership of the state. It is planned that by 2020, California will receive 33% of energy by means of "green" technologies.
