In spite of the intention of governments to increase the use of renewable energy in electricity supply, particularly the use of solar photovoltaic (PV) for energy poverty reduction in rural and peri-urban areas of Africa, there is relatively little information on how solar PV electrification impacts on energy poverty reduction. …
Clean Edge, which has been tracking the growth of clean-tech markets for nearly a decade, reports that global revenues for solar photovoltaics, wind power, and biofuels expanded from $75.8 billion in 2007 to $115.9 billion in 2008. For the first time, one sector alone, wind, had revenues exceeding $50 billion. …
To make solar cells more efficient, sprinkle them with silver MAKERS of solar cells face a dilemma. Purified silicon, the basic material of such cells, is expensive. The temptation, therefore, is to use less of it. As a result, the makers have developed a generation of cells whose silicon layers …
Captures all the sunlight, more efficient at making electricity the oldest piece of space junk still orbiting the Earth is the satellite Vanguard I. In 1958, it became the fourth artificial satellite launched

Buenos Aires: Tired of running out of batteries and having to find a socket to charge your cellphone or iPod? An Argentine fashion designer may have the answer: a timeless jacket with a built-in solar panel. Julieta Gayoso
biological sciences Frog, out of the well The frog, Odorrana tormota, is the only animal that can manipulate its hearing system to select particular frequencies. It helps the males to call and woo females. The system in frogs is also being used as a model for hearing aids. The rare …
Using mercury nanotubes india may be able to produce solar cells with a greater capacity to absorb solar energy. The secret behind this extra capacity lies in mercury compound nanotubes, scientists at iit Delhi have found out. Nanotubes, because of their structure, exhibit electrical and optical properties, which help in …
By N N Sachitanand Despite its limitations, the global growth rate of solar photo voltaic installations has spurted. Those who dislike nuclear energy because of its safety problems strongly tout solar energy as a clean and renewable alternate for India. India experiences clear sunny weather for over 250 days a …
Magic dyes: The dyes can double the efficiency of solar cells used today. A simple sheet of glass coated with dye could be enough to cut the costs of solar power. That's the claim from researchers who have created a
Of the reported 25 lakh homes worldwide that use solar home systems today, about" 3.6 lakh are in India, second only to China which has four lakh solar home system users. The market for solar photo voltaics (PV) continues to find its relevance in such decentralized off-grid applications because despite …
The radiations from the sun can be converted into electrical energy using devices like solar cells. The device that can directly convert solar energy into usable electrical energy is known as solar cell or photovoltaic cell. The voltage generated from a single photovoltaic cell is typically only a fraction of …
A recent development in solar energy is a solar tower/chimney.It is a method used for large-scale generation of electricity from solar radiation.The principle is very simple.It is based on the well known principle of greenhouse effect,chimney updraft effect, and wind turbine. Ambient air is drawn into a very large circular …
inorganic solar cells used today are also quite bulky. Initial costs also seem to be a major deterrent in the spread of solar energy. A us-Austrian team led by 2001 Nobel laureate Alan Heeger has gone some way in mending matters. In 2005, the team had come up with a …
The Government has received an application from Phoenix Solar India for setting-up a Rs 1,200-crore solar PV cell and module project in the country, taking the total number of proposals under the new scheme for semiconductor fabs and other micro and nano technology manufacturing industries, to eight. According to sources …
Hi-tech investments: The Minister for IT & Communications, Mr A. Raja, addressing a press conference in the Capital on Thursday. New Delhi, April 3 Marking the largest-ever project under the new semiconductor policy, Mukesh Ambani-led Reliance Industries Ltd (RIL) has approached the Government with plans to set up a semiconductor …
Solar cells generate electricity from sunlight without producing' pollution, but some environmentalists have been concerned about the potential negative impact of this photovoltaic technology. This is because the manufacture of solar cells involves toxic metals such as lead, mercury and cadmium and produces carbon dioxide, which contributes to global warming. …
Tokyo Electron, a leading maker of semiconductor equipment, is set to develop solar cell manufacturing equipment through a joint venture with Sharp in an effort to capitalise on demand for clean energy. The two Japanese companies plan to develop production equipment for thin-film solar cells. Tokyo Electron will produce and …
a new nanowire promises to revolutionalize the world of nanotechnology. Developed by scientists at Harvard University, the wire, which is a fraction of the width of human hair, will function as a solar cell, generating power for its own use, and other nanodevices. Scientists say the nanowire is more efficient …
