Brite Solar, based in Athens, Greece, is developing 3rd generation photovoltaic technology to produce solar windows for homes and office buildings. Brite Solar’s PanePower Solar Technology is based on Building Integrated PV (BIPV) market, growing substantially from $528 million in 2008 to

Twin Creeks Technologies. A new era in thin crystalline wafers.

March 19, 2012 in Solar

There’s been a lot of buzz lately about the San Jose-based “stealth” solar company Twin Creeks that recently came out of hiding with its ground-breaking Proton Induced Exfoliation (PIE) manufacturing technology that efficiently produces ultra-thin solar cells to reduce solar cell costs by up to 50%. Like 1366 Technologies, Twin Creeks optimizes solar panel manufacturing by [...]

ReVolt House. Energy adaptive floating unit.

February 22, 2012 in Efficiency, Solar

The ReVolt House is a rotating and floating solar home, designed by a team from the Delft University of Technology (TU Delft).  The Revolt House is part of the 2012 Solar Decathlon, the “world cup” for sustainable solar houses. The name ReVolt has a tri-fold reference to the essence of the house: REVolving, VOLTage (referring to its self-powered [...]

Do The Bright Thing. Shop your way to a sustainable solar future.

February 20, 2012 in Solar

Imagine you order a camera or a new book online, and several days later, you find out that your purchase also contributed to the investment of a solar project. Do The Bright Thing, based in the Netherlands, has developed a creative financing model for solar projects through online shopping.  With Do The Bright Thing’s shopping [...]

Solaire 2G. 2 in 1 solar.

January 20, 2012 in Solar

Solaire 2G, based in Marseille, France, is developing  a novel and patented dual-purpose solar panel that combines PV and heat exchanger technology to produce both electricity and hot water. Standard PV panels are about 15% efficient, and effectively the remaining 85% is lost — as heat.  Solaire 2G’s design includes a heat exchanger that extracts [...]

Wysips. What you see is photovoltaic surface.

January 16, 2012 in Solar

Wysips, based in Lambesc, a small village in the South of France, is developing a transparent solar film technology that can be seamlessly integrated onto the screen of a smartphone — and replace the need for chargers and wall sockets. Wysips envisions implementing the solar technology on a wide range of applications from billboards to [...]

Alion, Inc. Solar cells manufactured by acoustic printing.

January 4, 2012 in Solar

Based in Richmond, CA, Alion is a stealth solar company using acoustic printing techniques to manufacture low-cost cadmium telluride (CdTe) solar cells. As Mark Topinka, one of the Alion founders, describes on his LinkedIn page, Alion is “working hard on the world’s lowest $/W solar cell”. Acoustic printing is a technology originally developed by Xerox [...]

Solarus. Unlocking solar energy.

November 30, 2011 in Solar

Solarus, located in Stockholm, Sweden, develops an innovative but gorgeously simple solar technology based on a concentrating solar capture technology. Solarus’ technology is designed such that solar energy is absorbed from the top of the PV panel as well as from underneath, using their MaReCo (Maximum Reflection Concentrator) technology, and concentrating the received sunlight by [...]

Bandgap Engineering. Nanowire-enhanced solar cells.

November 17, 2011 in Solar

Bandgap Engineering‘s innovative nano-siliconTM technology combines low-cost processing and increased efficiency for solar PV to be cost-competitive with the grid. Silicon nanowires are structures with a diameter on the order of a nanometer (10-9 meters).  Nano-silicon has several advantages over “bulk” silicon, namely that it can be “tuned” to greatly reduce reflection and increase absorption, two key [...]

LuminAID. An inflatable solar light.

November 8, 2011 in Appropriate Technology, Solar

Incubated at Columbia’s Graduate School of Architecture, the LuminAID solar lamp is an ultra-portable, water-proof, solar-powered lamp.   The LuminAID lamp’s solar system is designed for people without regular access to electricity and for victims of a natural disaster.  In other words, the lamp is designed to be robust, portable, waterproof, and … a safer and [...]

1366 Technologies. Solar manufacturing for the 21st century.

November 1, 2011 in Solar

If you know anything about the solar industry (which is likely more than I do), you’ve probably heard of 1366 Technologies.  Based in Lexington, MA and named after the solar constant (not a street address like 1369, one my favorite Cambridge coffeeshops), 1366 has developed a novel manufacturing technique to produce silicon wafers by casting (in [...]

NOKERO and Enèji Pwòp. Bringing solar-powered light to rural Haiti.

October 26, 2011 in Appropriate Technology, Solar

The staff of Watt Now is finally back from Haiti! And we’ve got lots of exciting projects to report on.  And yes, we realize as Mark Twain said, that “only royalty, presidents, editors and people with tapeworms have the right to use the editorial ‘we’ “… Anyway, as I previously mentioned, EarthSpark International is a [...]
