Tonio Buonassisi Seeks to Make Solar Cells Competitive

January 15, 2015 by Energy @ MIT

Solar Cells and Market Competitiveness

One day, as he was riding home from high school in São Paulo, Tonio Buonassisi looked out the bus window at the city’s long lines of traffic, and its smoggy haze. It was then he realized that there had to be better ways for people to produce and use energy, and that he wanted to try to do something about it.[read more]

Recycling Old Batteries into Solar Cells

August 19, 2014 by Energy @ MIT

Batteries Recycled Into Solar

This could be a classic win-win solution: A system proposed by researchers at MIT recycles materials from discarded car batteries — a potential source of lead pollution — into new, long-lasting solar panels that provide emissions-free power.[read more]

Happy 60th Anniversary to the Modern Solar Cell

April 27, 2014 by Eric Wesoff

Solar Cell History

The pioneering engineers of the modern solar cell gathered in person and in spirit recently in Palo Alto, California to celebrate the 60th anniversary of their invention. Little did they know the impact their discovery would be having on utilities in 2014.[read more]

Wall Street Suddenly Loves Solar, Just In Time For New Solar Cell Efficiency Breakthrough

January 7, 2014 by Tina Casey

Wall Street and Solar

Over the weekend, the New York Times noted that the solar power “craze” is partly responsible for Wall Street’s recent good times. The Times used the example of solar giant SolarCity, but this could just be starters for the US solar industry.[read more]

Record Breaking Solar Cell Efficiency From A 'Perfect Crystal'

November 2, 2013 by Tina Casey

Solar Cell Breakthrough

Gallium is already on its way to becoming the workhorse of the solar tech field, and now a team of US scientists has hit upon an improved method for growing indium gallium nitride crystals that could lead to record-breaking solar cell efficiency.[read more]

Cost Of Solar Set To Plummet With New 44.7% Efficiency Record

September 27, 2013 by Tina Casey

Solar Efficiency Record

A research team in Europe has achieved a world record-setting solar conversion efficiency of 44.7 percent, and assuming that higher efficiency translates into lower costs, it’s yet another indicator that we’re only at the beginning of a long, steep decline in the cost of solar power.[read more]

Energy Innovation: Low Cost Solar Cell Assembles Itself

May 30, 2013 by Tina Casey

the future of solar energy?

Researchers from Rice University and Penn State have developed a relatively efficient organic solar cell based on a compound polymer that assembles itself into tidy bands.[read more]

Being a Solar Hero and Lessons on Leadership

June 7, 2010 by Christopher Williams

I am a solar hero. Well, almost. For the past month I’ve been running a crew installing solar in Roxbury. I’d say we’ve installed about 50kW in the past month, not bad on a pitched roof. This is some of our work to the right. The name solar hero started as a joke around the job site but mainly is used to talk about anyone who kicks...[read more]

Scientists develop glitter-sized solar cells

December 23, 2009 by ToddWallace

Sandia National Laboratories scientists have developed glitter-sized photovoltaic cells that use 100 times less silicon and generate the same amount of energy as conventional solar cells. The cost reduction is due partly to the fact the microcells don’t need a lot of material to become highly efficient and well-controlled...[read more]

Tianjin Staging Up for Cleantech

November 13, 2009 by Richard Brubaker

From Cleaner Greener China Tianjin’s Economic Development Zone (TEDA) has been one fo the premier investment zones in China, and keeping in mind their proximity to the new Singapore invested ecocity, it should come as no surprise that this would lead to some very large cleantech projects for TEDA. Here are three that they recently...[read more]

Solar materials expand in Malaysia

August 13, 2009 by Doris de Guzman

Asia's renewable energy market really seems to be booming as reports indicated (I will write an article soon about China's renewable energy market!). The usual suspect of course is China but I saw several investment news in India last week and now this one from Japanese chemical company Tokuyama announced this week that it is building a...[read more]

Was Moore's Law Inevitable?

July 30, 2009 by Big Gav

Kevin Kelly has an interesting (and long) article on the history of Moore's Law and exponential growth in technological capability, including some notes on its relevance for solar PV production - Was Moore's Law Inevitable?.Finally, in a another reference, Mead adds : "Permission to believe that [the Law] will keep going," is what keeps...[read more]

Airborne solar cells to power unmanned Air Force vehicles

July 30, 2009 by ToddWallace

Scientists at the University of Washington’s Multidisciplinary University Research Initiative are working on dye-sensitized solar cells that would coat the skin of unmanned US Air Force vehicles. The new airborne solar cells are made by blending a flexible film and a thin glass coating with transparent conductive electrodes. Taya has...[read more]

Latitude-specific solar cells

July 2, 2009 by Lynne Kiesling

How cool is this? Solar cells that can tune to the light angle and quality at different latitudes: Quantasol has now created GaAs [gallium arsenide] solar cells that can be tuned to the prevailing light conditions of a particular place, to get the most out of the cells wherever they are. To do that, the firm added indium gallium arsenide...[read more]

Solvent Free Dye Sensitized Solar Cells

June 30, 2008 by Jonathan Smith

In 1991 Grätzel and o’Regan demonstrated the first example of a photoelectrochemical solar cell, a DNSC (Dye-sensitized Nano-structured Solar Cell), which could deliver a competitive light-to-energy conversion efficiency and promised sufficient stability for mass production. Since then, material scientists have focused upon SAMs (Self...[read more]
