Scientists at the University of South Wales have imposed a new world record by creating the first silicon solar cell that reaches an efficiency of 25%.
The team leader, Prof. Martin Green, said that his solar cell is 6% more efficient than any previous technology. This record is very close to the theoretical limit of 29% [...]
The ecology in the technology sector is no longer a matter of political correctness, let alone to become a selling point by way of savings.
A couple of years ago the green flag was raised: the technology was not necessarily synonymous with pollution and companies began to do their homework to get out of the lists [...]
By using two different types of chemicals to create the features recorded on the scales of microns and nanometers, researchers at the Georgia Institute of Technology have developed a surface treatment that increases the light absorption of silicon photovoltaic solar cells in two complementary ways.
The surface treatment which increases absorption both by the capture [...]
Currently two renewable energy technologies are being tested in Guatemala
1) An electric power micro-generator 2) $100 Solar Heaters
Micro Power Generator
This product is a micro-renewable power generator with currents as low as 3 gallons per second, ideal for the mountainous areas of Guatemala. This generator was created by XelaTeco, a business incubator located in west Guatemala.
XelaTeco [...]
Developed by scientists at the Department of Marine Sciences and Applied Biology, University of Alicante in collaboration with the company BioFuel BFS Systems, the compounds that get this prototype have a value in the market, with an efficiency ten thousand times greater than that of any other known energy crops.
The International Congress of Biomass Obtaining [...]
New solar energy technologies, we bring you the best ones:
• Ultra thin and flexible solar cells without silicon, reaching up to 19.9% efficiency.
• Inflatable balloons that serve as solar collectors and cover a larger surface area of collection are inexpensive, functional and produced by Earth Cool.
• Sunrgi Solar Cells with minimum costs achievable through the cells cooling and [...]
Technological change is steadily improving yields of cells.
This type of energy used to supply electricity to many villages and factories in Senegal, Jordan, Brazil, Philippines, Indonesia and Chile. World production is 60 megawatts per hour a year. In Spain are 25,000 households benefiting from this type of energy.
Having the unique advantages of this type of [...]
President Barack Obama announced today the creation of a new working group for development of alternative energies, including clean coal.
In a meeting with governors of several coal-producing states, Obama defended the need for a comprehensive bill on energy, said that clean energy will “of benefits.”
“The decision in other countries to follow suit and [...]
Solar Hydrogen Energy Corporation Labs has announced that they have developed the most efficient solar energy technology in the world. Although only in the state of a prototype SEHC has developed ways to concentrate sunlight to levels 5,000 times greater than it would normally fall on the Earth’s surface.
By focusing the light through a tube [...]
Nissan has figured out a way to keep the batteries of its newly manufactured cars fresh until they reach the customer – solar energy. The manufacturer announced today it has signed a sales contract with solar product maker ICP Solar Technologies for an automotive solar charger.
Newly manufactured cars can sit in a parking lot for [...]
