By rss@youtube.com (photovoltaicsint) Canadian Solar Vice President of corporate development, Robert Patterson, caught up with our very own Mark Osborne a little while ago. Together they cover the challenges of CSI's new metalurgical grade silicon product line which Robert says should account for 150MW - 200MW of producti...

In 2006 for the first time over the half of world's polysilicon supply was used for production of renewable electricity solar power panels. Currently, there are only twelve production plants for solar grade polysilicon in the world. ...

Evergreen Solar develops, makes and sells String Ribbon silicon wafer solar power products used in solar panels. In the past four weeks, Evergreen has posted seven technical and management jobs at the Midland plant. It's being built near Dow Corning ...

Crystal Solar Inc., based in Santa Clara, Calif., will develop thin crystal silicon solar cells on ceramic substrates. International Solar Electric Technology Inc., based in Chatsworth, Calif., (will develop low-cost, monolithically integrated, ...

Hemlock Semiconductor, which makes silicon for solar panels, is in the midst of a $1 billion expansion near Saginaw. Hemlock executive Gary Homan has high hopes for solar. Saginaw resident Kelsie Short says it's tough to find a job in town. ...

Schott Solar, a subsidiary of German glassmaker Schott, produces components for photovoltaic applications and solar energy power plants. It's an integrated manufacturer of crystalline silicon wafers, cells and modules. Schott North America CEO Gerry ...

 UK The roof of the new structure also features a 300-KW solar power system. The company, a joint venture between Schott Solar and Wacker Chemie, says that it intends to gradually expand its manufacturing capacity to 1 GW by 2012. ...

Silicon prices are expected to drop another 30% by year end. First Solar profits -- and its shares -- could get cut in half. ...On May 14, Phoenix Solar, a major customer in Germany, told investors it will switch from First Solar silicon-sparing ...

By Mike Millikin Sanyo Electric Co., Ltd. has broken its own record for the world’s highest energy conversion efficiency in practical size (100 cm2 or more) crystalline silicon-type solar cells, achieving a efficiency of 23.0% (until now 22.3%) at a research level for... Sanyo Electric Co., Ltd. has broken its o...

A lot of development work went into designing the solar power system into a compactor, which also is branded BigBelly, Kennelly said (see technical specs). On top of each bin is a 30-watt silicon solar panel that is protected by a polycarbonate shield. ...

 Germany In 1982, Kyocera successfully began mass production of multicrystalline silicon solar cells using the casting method, which has now become the mainstream method used in solar power generating systems today. Since then, Kyocera has carried out all ...

By Mike Millikin An untreated silicon solar cell only absorbs 67.4% of sunlight shone upon it. From an economic and efficiency perspective, this unharvested light is wasted potential and a major barrier hampering the proliferation and widespread adoption of solar power.

By Bill Chameides Photovoltaic solar cells come in a variety of forms. The one that's been with us the longest is the silicon solar cell. You can chalk up at least part of that improvement to competition, according to John Perlin, author of From

By Mike Millikin Using a volatile electrolyte, DSC technology has delivered efficiency of up to 11.0-11.3% measured under the standard air mass 1.5 global (AM 1.5G) sunlight—about half that of the best silicon solar cell. [AM 1.5G is the intensity of insolation equivalent to the sun shining through the atmos...

By Mike Millikin Silicon is the dominant semiconductor material used in present day solar cells, representing more than 93% of the photovoltaic cell market. The new result opens the door to the potential application of MEG for greatly enhancing the conversion efficiency of solar cells based on silicon...

By Mike Millikin This joint venture is Hydro’s third initiative within solar energy since November 2006 when it invested in the solar energy company Norsun. Norsun will open a factory producing monocrystalline silicon wafers in Årdal, Norway. Hydro has also invested in the US company Ascent Solar, whic...
