Photo voltaic cells convert solar light photons into electricity. Photovoltaic solar cells fulfill two functions: photogeneration of charge carriers (electrons and holes) in a light-absorbing material, and separation of the charge carriers to a conductive contact that will transmit the electricity. Solar cells are commonly used in remote locations where cost-effective access to local power grids are not possible. The following articles contain information relating to solar photovoltaic technology and developments.
Solar panels need silicon for absorption of light. Silicon doesn’t come cheap.This cost-factor is preventing people from using solar energy on a large scale. Scientists utilize another substance i.e.
Conventional solid-state solar cells are suffering from the problem of the bandgap voltage limitation. Scientists are trying to capture more and more of sunlight and convert it into electricity.
Science continues to amaze and one of the latest discoveries may literally change the world as we know it. This tiny solar-powered sensor can fit on the face of
As the world continues its quest to use less fossil fuels, the latest possible solution comes from the most unlikely of sources: the tobacco plant. This latest news comes
What can a scientist do with salad dressing apart from telling you that it increases the taste of salad manifold? But that’s the beauty of this profession. As Newton
Tiny, glitter-sized solar cells have been developed by the Scientists at Sandia National Laboratories. It might turn out to be the perfect alternative energy preference for the holiday
Robins has time and again been considered as a pioneer in testing alternative energy technologies. Recently they have installed a solar panel which is a matter of curiosity. Their
You can think of it as origami — very high-tech origami. Researchers at the University of Illinois are working on the same good old silicon but they are taking
When we think about going solar we make a mental picture of large heavy panels adorning one’s rooftop. But researchers are trying to get rid of bulky solar panels.
We still have to miles to cover before solar power can replace the fossil fuels and become a cheap and effective solution for common folks. But it is indisputable
MIT professor Daniel Nocera earlier worked on a catalysts that can divide water molecules which can be utilized to store energy. Daniel Nocera has established a company named as
IMEC (Interuniversity Microelectronics Center) has presented a large-area solar cell with 18.4% conversion efficiency at the ongoing European Photovoltaic Solar Energy Conference (Hamburg, Germany). A world leader in its
The Eindhoven University of Technology and University of Ulm scientists have successfully developed the first high-resolution 3D images of the internal structure of a hybrid polymer solar cell. This
Silicon is one of the basic but expensive materials used in designing solar panels. If we can use something else as effective as silicon but more economical, solar power
Sunlight is a non exhaustible source of energy without contributing greenhouse gases to the atmosphere. Still it is miles away from replacing the fossil fuels. Many reasons can be
We all are familiar with the positive impact of alternative energy on our environment. Now researchers are trying to improve upon the existing alternative energy technology. As far as
Stirling Energy Systems (SES) and Tessera Solar worked jointly and have come out with their precious device called SunCatchers(TM). They exhibited their four newly designed solar power collection dishes
When one lives in a developed country it becomes hard to visualize that how people manage in those parts of the world where electricity is still a distant dream.
There are two things that prevent solar cells from entering the mainstream: their prohibitive cost, and their inadaptability. Even if people can somehow overcome the cost barrier, the havoc
Just imagine your neighborhood mason fitting your roof tiles and these same tiles producing dependable solar energy for your house or office – you no longer need to hire
Not even in our wildest dreams have we anticipated that while we are simply looking out the window enjoying the outside view our windows can simultaneously produce energy for
Researchers at Pacific Northwest National Laboratory (PNNL) in Richland have developed flexible solar panels that could be installed on roofs like shingles. This technology was originally used to protect
For centuries we have been using fossil fuels for industrial and domestic purposes. Most of us consider fossil fuels cheap. But now we are realizing the “real” costs of
The alternative sources of energy are constantly evolving. Scientists and manufacturers are trying to come up with better products that are user friendly and economical. Government is drawing policies
Akira Fujishima, thirty-five years ago, discovered the electrochemical properties of titanium dioxide. He showed that titanium dioxide functioned as a photocatalyst. It produced hydrogen gas from water, electricity and
