Stacking Solar Cells Could Vastly Improve Their Efficiency

semprius_solar_cell

Harvesting solar energy is a great way to generate sustainable power, but unfortunately solar cells are far from being as efficient as they might be. Currently, commercially available solar cells can convert about 25 percent of sunlight into electricity, and scientists have been trying to create better solar cells for years. One milestone they have been unsuccessfully trying to reach is 50 percent conversion efficiency of solar cells. However, the start-up company Semprius might be on the right track with the stacking technique of solar cells they recently developed.

Dr. Jon Major, a researcher at Liverpool University has recently made the discovery that the chemical used to make tofu, and bath salts, could also be used to replace one of the most toxic substances, namely cadmium chloride, that are used to manufacture solar cells. Using salts to replace cadmium chloride in solar cell production would also make them much cheaper. His study was published in the journal Nature.

New Way of Cooling Solar Cells

Basic RGB

A group of researchers at Stanford University have developed a new type of coating, which will allow solar cells to cool themselves. This breakthrough would eliminate the need for water and energy intensive coolants and ventilation, which is currently used to cool solar cells. It would also extend the life span of the solar cells considerably.

A Super Portable Solar Charger

When traveling to remote areas, charging your phone or tablet can be quite a hassle. But the portable solar charger SunJack, which was created by Harold Tan, can make this problem go away. The solar charger is also a great emergency kit addition for off-the-grid travel. SunJack is very portable, as it folds up to the size of an iPad. The creator will also be donating a part of the sales to help give the villagers in Papua New Guinea healthy, access to non-toxic lighting, since in these areas the people still use lighting that is quite hazardous.

A team of researchers at the University of Michigan has successfully developed a prototype of a semi-transparent photovoltaic solar cell, which they hope will make solar arrays more attractive to consumers and lead to a more widespread adoption. Existing solar panels are far from aesthetically pleasing, but this new invention could be used to cover the sides of buildings, window shades and even billboards without obscuring what lies beneath.
