High-Efficiency In The Conversion Of Solar Energy: Beyond The Shockley-Queisser Limit by Solar Energy Blog on Nov 5, 2009It is common in the field of renewable energy use the argument that the Sun is the most abundant energy source on our planet, but it’s interesting to go deeper into this statement and for that use some data from Martinez-Val. For a start if we...

Solar Efficiency Hits Record Again by Solar Energy Blog on Oct 31, 2009Virtually every week we find news about someone breaking the record for efficiency of a solar cell, and while we have published some of them we haven´t posted them all, because that’s the difference between 25.7% and 25.8%, we do not really be...

A New Powerhouse in Solar by Solar Technology Stocks on Oct 7, 2009Back in 2007, Dow Chemical (NYSE: DOW) won a $20 million grant from the Department of Energy to research and develop building-integrated photovoltaics (BIPV) products. The fruits of that government-sponsored labor are Dow's Powerhouse Solar Shingle,...

New World PV Efficiency Record by Solar Technology Stocks on Sep 25, 2009Making solar cells and modules as efficient at converting light to electricity as possible has been a long-standing goal in the solar photovoltaic space. Much progress has been made in the past few years, but this week world-record breaking efficienc...

Efficienct Solar Energy Panels by Solar Energy Blog on Sep 23, 2009In few years solar energy will be able to compete with conventional sources of energy; it all depends on the technological improvements of the solar modules and the higher efficiency in solar panels. Mr. Shauwn-Yu Lin from the Politechnique Rensselae...

- by Blog On Smog on Sep 15, 2009Solar Trackers Solar tracking devices, mounted with photovoltaic (PV) panels, allow the panels to exactly track the sun's path across the sky and can increase the yield of solar energy installations by as much as 40 percent compared to stationary...

Sunpower Will Try Lower The Cost Of Solar Energy By Half By 2012 by Solar Energy Blog on Aug 31, 2009The manufacturer of solar cells and panels Sunpower said that only 4 years in its technology, which is one of the most efficient market, can produce solar electricity by half the current price. The vice president of Sunpower William Mulligan spoke Th...

MIT Solar Concentrator Improves Efficiency of Solar Cells by Solar Energy Blog on Aug 21, 2009MIT Solar Concentrator Innovation Solar concentrators do what you expect, concentrate sunlight. Generally they are large mirrors or other devices, but the goal of any solar concentrator is to concentrate the light that falls on a large area in a sma...

The Most Efficient Solar Energy Collectors by Solar Energy Blog on Jul 25, 2009The two mega solar companies Stirling Energy Systems and Tessera Solar has submitted a new generation of its famous Suncatcher system, four models with a design much more efficient dish-shaped solar collectors. They will be available for use in comme...

Spray Coating for Solar Panels by Solar Energy Blog on Jul 15, 2009Last week we talked about a new coating to improve the efficiency of solar panels. This time, it is not the same kind of coating (still can see that the coating can be improved in the short term), but the Australian company Solar Spark Braggone and F...
