I couldn’t help but notice and interesting article in Newsweek which contained an interview with President Obama’s Energy Secretary Steven Chu concerning one of the administration’s top priorities: a new energy policy. Interestingly, Dr. Chu supports research into burnable biofuels which could replace gasoline, while he also supports decreasing carbon emissions. While biofuels such as […]

Solar Energy History-Present-Future
The genesis of solar energy history goes way back to the year 1838 to an observer by the name of Edmund Becquerel who at that time had published findings on the capability of materials to change light into raw energy. Although it was fascinating at that time no one took the opportunity to pursue it […]
CES 2014 Spotlight: The Sun of the Parts
They may be charged from the same source, but solar panels are not made the same. Solar powered devices and charging units are making an impact in the consumer electronics sector, but there’s much that needs to be known about the different products. Expert Craig Adam of Secur gave a brief education on what to […]
How To Evaluate Solar Cells
How to test our solar cellsYou can test out your solar cells on a clear warm day,if possible during summer when the sun is in its maximum point in the solstice,or near solar noon. However you need not await summer time to evaluate them. You can test your solar cells at any time of the […]
Information on Solar Energy for Kids
The sun is a star that is full of gases which are continuously burning. It’s just like a stove or a range that emits heat when it burns. But the amount of gas that is burnt is very large in case of the sun. The burning of gases makes the sun very, very hot. The […]
Solar Plane Impulse Completes 26-Hour Flight Over Switzerland
The solar plane Impulse has landed after an over 26-hour flight in the skies over Switzerland. The Impulse, which has a 210-foot wingspan, was powered by a bank of 12,000 solar cells, which kept batteries charged for electric power for the engine. According to the New York Times: “The propeller-driven Solar Impulse, made of carbon […]
Solar Panel Efficiency
With increase in consumption of electricity, the sources for generation of electricity have also increased. Solar energy is an inexhaustible source and can be harnessed to generate electricity. Solar cell is the main device that captures the solar energy and converts it into electric energy by the mechanism of photovoltaics. Solar cells are assembled to […]
Possible Explanation for the Inefficiency of Organic Solar Cells
Organic Solar Cells On the subject of renewable energy, intensive study of low-cost materials and processes is indispensable in order to come up efficient methods of energy production. Photovoltaic energy conversion is the process of transforming part of the solar electromagnetic spectrum (radiation) into electricity through the use of devices that are called solar cells. […]
The Practical Science Behind Solar Cells
Recent breakthroughs promise to dramatically improve the output of solar cells. Scientists at MIT have developed a new solar cell that increases power by a “factor of over 40”. The technology employs “organic solar concentrators” to increase power conversion. Nobel Prize winner Alan Heeger, Professor of Physics who teaches in the University of California system, […]
Applications of Solar Energy: Part-3: Solar Photovoltaic Cells
What is a Photovoltaic Cell Solar energy, an important form of renewable energy, is being used extensively in solar water heaters and solar cookers. Solar energy is also being used on the large scale for generating electricity by using the devices called solar photovoltaic cells or solar cells or PV cells. Photovoltaic cells are
