Minor Changes To the Tiniest Parts In Solar Cells Yields Surprising Rise In Efficiency

A team of engineers from University of Buffalo has been able to significant increase the conversion rate of solar-energy technology by tweaking the tiniest parts of the cells. At University of Buffalo, researchers have already demonstrated that embedding quantum dots into modern photovoltaic cells increase the energy output significantly. It allows the cells to generate [...]

Will Mars Be a Hub For Nuclear Energy Or Solar Power?

Opportunity and Spirit were the two last NASA Mars rovers sent to outer-space in 2003. They used solar energy as a source of energy. However, from Cape Canaveral, in November 2011 another rover has started its mission but with nuclear power. Spirit and Opportunity – Solar Powered Rovers Apparently, solar power and nuclear power have [...]

Reviewing The Future Design Of Solar Technology

Solar technology is becoming more and more flat. This applies to household solar panels, industrial solar arrays in the desert; Solar panels are literally defined by its flat shape. Yet, solar panels do not need to be flat. In our natural world, practically nothing is flat and therefore why should solar panels continue to have [...]

Affordable Thermal Solar Energy For Home Use

Solar thermal is probably the cheapest source of household heated water: besides the initial investment, the convertor will function at no cost, harvesting a free source of energy – sun’s thermal radiation. Such a device could provide from 30% to 80% of the warm water needed for a family of four, depending on the total [...]
