IMOMEC, associated laboratory of IMEC, located on the Hasselt University campus; developed a method to stabilize the morphology of nano-solar cells, and it resulted an impressive improvement.
With these stable solar cells efficiency can be compared with the standard ideals of organic solar cells. This discovery paves the way for commercial solar cells with a lifespan [...]
American Greg Johanson developed in 1981 a car tricycle with photovoltaic solar cells half horsepower, 60v with a direct current motor powered by a five-under 12 V batteries connected in series and charged five of 35 solar modules w.
His average speed was 50 km / h. The pioneer vehicle was stolen and never recovered, but [...]
The solar energy program Risø has been conducting research in polymer solar cells, an inexpensive alternative to existing silicon solar cells. The investigation is now in a late stage a demonstration plant was built at Risø DTU.
Since the start of Risø’s research on solar cells based on polymeric materials has had a strong emphasis on [...]
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% [...]
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 [...]
Silicon is still the most popular material for the manufacture of most solar cells for commercial applications because it is abundant in nature. To be useful in solar cells must be refined to 99.9999% purity.
The molecular structure of a single silicon solar cell is uniform, making it ideal for efficient electron transfer. To make an [...]
The manufacturing process of a photovoltaic cell consists of two distinct parts:
Preparation and purification of semiconductor using silicon, germanium, and gallium arsenide. Manufacture of photovoltaic cell itself.
The process for manufacturing a monocrystalline silicon cell is as follows:
The raw material is silica, which is extracted by reduction, obtaining the so-called metallurgical silicon with a purity of [...]
¿Pizza oven? ¿Solar Cells? There is something that really does not fit, but a 23 years old Australian scientist developed a method for manufacturing solar cells using enamel remover, a pizza oven and an inkjet printer. IJET was called, and is a technique so cheap that will revolutionize access to solar technologies.
Nicole Kuepper the creator [...]
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 [...]
Scientists from three institutions have revealed how nanotechnology may help improve the performance of solar cells at a lower cost.
Jessika Trancik of the Santa Fe Institute, Scott Calabrese Barton of Michigan State University, and James Hone of Columbia University say that a film of carbon nanotubes may be able to replace two of the layers [...]
