Stacking Solar Cells Could Vastly Improve Their Efficiency


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.

A Prefab Tiny House Retreat


Vivood, a Spanish architecture group, designed a tiny prefabricated house of the same name, which can be assembled in only about nine hours. Once assembled, it can be used as a guesthouse, retreat, or even a tiny home. When ordered, the prefabricated Vivood comes in easy to assemble modular parts, which already have all the necessary plumbing and electrics installed.

Reciprocity House is Worth Watching


Maison Reciprocity, or Reciprocity House, is one of the entrants in this year’s Solar Decathlon Europe competition. In a nutshell, it is an energy-efficient, highly sustainable modular home, which aims to set the standard of low cost, and low impact building in the future. It is a joint effort between Appalachian State University and the French Université d’Angers, and one of only two entries into the competition by US teams this year.

More Environmentally Friendly Solar Cells


Researchers at Northwestern University have developed a new solar cell that uses tin instead of lead perovskite as a collector of solar energy. This cheap and environmentally-friendly solar cell can therefore be made without any high-tech equipment or hazardous materials.

Is Wireless Transmission of Power Finally a Real Possibility?


Two Russian scientists, Leonid and Sergey Plekhanov, both of the Moscow Institute of Physics and Technology (MIPT) are trying to crowdfund the building of a prototype of Nikola Tesla’s Wardenclyffe tower, which could allow for wireless transmission of power. Should they succeed, it is conceivable that the entire planet could be powered by renewable energy sources with very little energy loss during transmission.

Could Tofu be the Answer to Greener Solar Cells?

University of Liverpool News

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.
