Arizona solar plant achieves six hours after sun goes down October 11, by Nancy Owano, Phys. Abengoa said Wednesday that the facility, about 70 miles southwest of Phoenix, can store the sun's power for six hours via thermal energy.
CC0 Public Domain University of British Columbia researchers have found a cheap, sustainable way to build a solar cell using bacteria that convert light to energy. Their cell generated a current stronger than any previously recorded from such a device, and worked as efficiently in dim light as in bright light.
This innovation could be a step toward wider adoption of solar power in places like British Columbia and parts of northern Europe where overcast skies are common. With further development, these solar cells —called "biogenic" because they are made of living organisms—could become as efficient as the synthetic cells used in conventional solar panels.
Solar cells are the building blocks of solar panels. They do the work of converting light into electrical current. Previous efforts to build biogenic solar cells have focused on extracting the natural dye that bacteria use for photosynthesis.
It's a costly and complex process that involves toxic solvents and can cause the dye to degrade. The UBC researchers' solution was to leave the dye in the bacteria. They genetically engineered E. The researchers coated the bacteria with a mineral that could act as a semiconductor, and applied the mixture to a glass surface.
Once installed, solar systems can be expected to last for 20 years or more and they require little in terms of regular maintenance. Best of all, the electricity they generate is free, so those. The North Carolina Clean Energy Technology Center has always striven to keep DSIRE a free and open resource, providing valuable information on thousands of policies and incentives for renewable energy and energy efficiency.

With the coated glass acting as an anode at one end of their cell, they generated a current density of 0. The holy grail, Yadav said, would be finding a process that doesn't kill the bacteriaso they can produce dye indefinitely.
He added that there are other potential applications for these biogenic materials in mining, deep-sea exploration and other low- light environments. The research has been published in the most recent edition of the journal Small.Solar power is the conversion of energy from sunlight into electricity, either directly using photovoltaics (PV), indirectly using concentrated solar power, or a ashio-midori.comtrated solar power systems use lenses or mirrors and tracking systems to focus a large area of sunlight into a small beam.
Photovoltaic cells convert light into an electric current using the photovoltaic effect.
