(Aug 2010)
One of the most promising technologies for making inexpensive but reasonably efficient solar photovoltaic cells just got much cheaper. Scientists at the University of Toronto in Canada have shown that inexpensive nickel can work just as well as gold for one of the critical electrical contacts that gather the electrical current produced by their colloidal quantum dot solar cells. **[[[http://www.physorg.com/news200070766.html 6]]]**
==== ""IBM"": Efficient Solar Cells from Cheaper Materials====
**{National Renewable Energy Lab & [[http://www.ibm.com/ IBM]]/ Dr.Matthew Beard}**
(Feb 2010)
Researchers at IBM have increased the efficiency of a novel type of solar cell made largely from cheap and abundant materials by over 40 percent. The new efficiency is 9.6 percent, up from the previous record of 6.7 percent for this type of solar cell, and near the level needed for commercial solar panels. The IBM solar cells also have the advantage of being made with an inexpensive ink-based process.

==== ""Sandia National Lab"": Revolutionary Tiny Solar Cells====
**{[[http://www.sandia.gov/ Sandia National Laboratories]] / Greg Nielson}**
(Jan. 2010)
The dimensions of these snowflake sized crystalline-silicon photovoltaic cells are merely 14-20 micrometers thick and measure 0.25 to 1 millimeters across i.e. only 10% as thick as regular ones. They also consume an estimated 100 times less silicon to produce the same amount of electricity compared to standard solar cells. Their efficiency level is 14.9%.
These cells attain their minuscule size due to the application of the techniques like microelectronic and micro electromechanical systems (MEMS).**[[[http://www.alternative-energy-news.info/tiny-solar-cells/ 2]]]**
==== ""First Solar"": The Solar Power Under $1 per Watt====
**{[[http://www.firstsolar.com First Solar]]/ Robert Gillette, CEO}**
(Aug. 2009)
Conventional technologies "have made the kind of progress that we were hoping futuristic technologies could make." For example, researchers have sought to bring the cost of solar power to under $1 per watt, and as of the first quarter of this year one company, First Solar, has done this. **[[[http://www.technologyreview.com/energy/23108/?a=f 3]]]**
==== ""Semprius"": Micro Solar Cells Handle More Intense Sunlight====
**{[[http://www.semprius.com Semprius]]/ Joseph Carr, CEO}**
(Feb. 2010)
A startup company hopes to bring down the cost of generating power with concentrated sunlight by using microscale solar cells that can utilize twice as much light as other panels, without the need for expensive optics or cooling systems. NC-based company Semprius developed using a novel microprinting technology, also offer significant savings on materials costs. In late January, the company announced a joint agreement with Siemens to develop demonstration systems based on its technology. Semprius plans to begin volume production of the modules in 2013.** [[[http://www.technologyreview.com/energy/24504/ 4]]]**

**{[[http://www.nrc-cnrc.gc.ca/nint-innt/index.html National Institute for Nanotechnology]] of U of Alberta/ [[http://www.chem.ualberta.ca/~buriak/Buriak.html Prof. Jillian Buriak]]}**
(Feb. 2009)
Plastic solar cells are made up of layers of different materials, each with a specific function, called a sandwich structure. Jillian Buriak uses a simple analogy to describe the approach: "Consider a clubhouse sandwich, with many different layers. One layer absorbs the light, another helps to generate the electricity,etc... Normally, the layers don't stick well, and so the electricity ends up stuck and never gets out, leading to inefficient devices". After two years of research, these scientists have, by only working on one part of the sandwich, seen improvements of about 30 per cent in the efficiency of the working model.** [[[http://www.sciencedaily.com/releases/2009/02/090225223324.htm 5]]]**

One of the most promising technologies for making inexpensive but reasonably efficient solar photovoltaic cells just got much cheaper. Scientists at the University of Toronto in Canada have shown that inexpensive nickel can work just as well as gold for one of the critical electrical contacts that gather the electrical current produced by their colloidal quantum dot solar cells. **[[[http://www.physorg.com/news200070766.html 6]]]**
==== ""IBM"": Efficient Solar Cells from Cheaper Materials====
**{National Renewable Energy Lab & [[http://www.ibm.com/ IBM]]/ Dr.Matthew Beard}**
(Feb 2010)
Researchers at IBM have increased the efficiency of a novel type of solar cell made largely from cheap and abundant materials by over 40 percent. The new efficiency is 9.6 percent, up from the previous record of 6.7 percent for this type of solar cell, and near the level needed for commercial solar panels. The IBM solar cells also have the advantage of being made with an inexpensive ink-based process.
The new solar cells convert light into electricity using a semiconductor material made of copper, zinc, tin, and sulfur--all abundant elements--as well as the relatively rare element selenium (CZTS). Reaching near-commercial efficiency levels is a "breakthrough for this technology," says Matthew Beard, a senior scientist at the National Renewable Energy Laboratory, who was not involved with the work. **[[[http://www.energyharvestingjournal.com/articles/ibm-claims-world-record-by-creating-high-efficiency-solar-cell-00002044.asp?sessionid=1 1]]]**

The EPFL scientists propose a new solution to replace the potential dangerous use of a liquid electrolyte within Grätzel solar cells. In this case they use an electrode created by the auto-assembly of titanium oxide nano-fibers.

(Dec 2010)
The EPFL scientists propose a new solution to replace the potential dangerous use of a liquid electrolyte within Grätzel solar cells. In this case they use an electrode created by the auto-assembly of titanium oxide nano-fibers. The scientists have demonstrated a level of efficiency three times greater than comparable electrodes so far developed. The result is a robust Grätzel cell that is capable of converting 5% of solar energy.... **[[[http://actu.epfl.ch/news/evolution-des-cellules-gratzel-performantes/ 8]]]**

(Aug 2010)
One of the most promising technologies for making inexpensive but reasonably efficient solar photovoltaic cells just got much cheaper. Scientists at the University of Toronto in Canada have shown that inexpensive nickel can work just as well as gold for one of the critical electrical contacts that gather the electrical current produced by their colloidal quantum dot solar cells. **[[[http://www.physorg.com/news200070766.html 6]]]**
==== ""IBM"": Efficient Solar Cells from Cheaper Materials====
**{National Renewable Energy Lab & [[http://www.ibm.com/ IBM]]/ Dr.Matthew Beard}**
(Feb 2010)
Researchers at IBM have increased the efficiency of a novel type of solar cell made largely from cheap and abundant materials by over 40 percent. The new efficiency is 9.6 percent, up from the previous record of 6.7 percent for this type of solar cell, and near the level needed for commercial solar panels. The IBM solar cells also have the advantage of being made with an inexpensive ink-based process.
The new solar cells convert light into electricity using a semiconductor material made of copper, zinc, tin, and sulfur--all abundant elements--as well as the relatively rare element selenium (CZTS). Reaching near-commercial efficiency levels is a "breakthrough for this technology," says Matthew Beard, a senior scientist at the National Renewable Energy Laboratory, who was not involved with the work. **[[[http://www.energyharvestingjournal.com/articles/ibm-claims-world-record-by-creating-high-efficiency-solar-cell-00002044.asp?sessionid=1 1]]]**

(Jan. 2010)
The dimensions of these snowflake sized crystalline-silicon photovoltaic cells are merely 14-20 micrometers thick and measure 0.25 to 1 millimeters across i.e. only 10% as thick as regular ones. They also consume an estimated 100 times less silicon to produce the same amount of electricity compared to standard solar cells. Their efficiency level is 14.9%.
These cells attain their minuscule size due to the application of the techniques like microelectronic and micro electromechanical systems (MEMS).**[[[http://www.alternative-energy-news.info/tiny-solar-cells/ 2]]]**

(Aug. 2009)
Conventional technologies "have made the kind of progress that we were hoping futuristic technologies could make." For example, researchers have sought to bring the cost of solar power to under $1 per watt, and as of the first quarter of this year one company, First Solar, has done this. **[[[http://www.technologyreview.com/energy/23108/?a=f 3]]]**

(Feb. 2010)
A startup company hopes to bring down the cost of generating power with concentrated sunlight by using microscale solar cells that can utilize twice as much light as other panels, without the need for expensive optics or cooling systems. NC-based company Semprius developed using a novel microprinting technology, also offer significant savings on materials costs. In late January, the company announced a joint agreement with Siemens to develop demonstration systems based on its technology. Semprius plans to begin volume production of the modules in 2013.** [[[http://www.technologyreview.com/energy/24504/ 4]]]**

(Feb. 2009)
Plastic solar cells are made up of layers of different materials, each with a specific function, called a sandwich structure. Jillian Buriak uses a simple analogy to describe the approach: "Consider a clubhouse sandwich, with many different layers. One layer absorbs the light, another helps to generate the electricity,etc... Normally, the layers don't stick well, and so the electricity ends up stuck and never gets out, leading to inefficient devices". After two years of research, these scientists have, by only working on one part of the sandwich, seen improvements of about 30 per cent in the efficiency of the working model.** [[[http://www.sciencedaily.com/releases/2009/02/090225223324.htm 5]]]**
