August 3, 2010 (Investorideas.com renewable energy/green newswire) Investorideas.com and its green investor portals provide the following Q&A for investors following solar stocks and the solar industry, with Tom Djokovich, CEO of XsunX, Inc. (OTCBB: XSNX), a solar Company developing CIGSolar™ Technology.

 

 Q: Investorideas.com

Tom, your company has been in the solar industry for years and witnessed the changes in technology. Crystalline silicon photovoltaic technology, first developed over 50 years ago is now being surpassed with greater efficiencies with thin film.  It is a race for greater efficiencies. For investors, can you give us your inside perspective on the changes in the industry and how your company has evolved with the industry?

 

 A: Tom Djokovich, CEO of XsunX, Inc. (OTCBB: XSNX)

The industry is certainly evolving in a number of areas. Silicon has been the dominant technology and still is today with about 8 out of every 10 solar modules made using silicon. While I do not see this changing overnight thin films have begun to make major in roads into the market, but so far this has been due to lower per watt pricing.

 

The next opportunity for thin films to compete and surpass silicon’s dominance will be driven by offering lower costs and silicon type performance. That is where XsunX is focusing its efforts with a next generation thin film technology based on Copper Indium Gallium Diselenide “CIGS”. CIGS holds the record for thin film efficiencies at nearly 20% so it holds the potential to delivery silicon type efficiencies, but is also benefits from lower production costs. As a matter of fact CIGS is where a number of industry experts believe that the next major costs reductions will come from.

 

Q: Investorideas.com

XsunX, Inc. (OTCBB: XSNX) is working a next generation of solar, developing CIGSolar™ Technology. Can you tell us what CIGS thin film solar is and what are its advantages?

 

A: Tom Djokovich, CEO of XsunX, Inc. (OTCBB: XSNX)

CIGS has several characteristics that make it one of the most valuable and promising PV materials.

● First, is CIGS’s absorption coefficient (how easily it absorbs and converts solar energy into electricity), which is among the highest for semiconductor materials used to make solar cells. Ninety-nine percent of the light incident on a CIGS based solar cell is absorbed in the first micrometer of the device. This provides the opportunity to produce thinner films and to reduce material costs significantly.

● Next, CIGS films retain their performance properties better and do not degrade as rapidly as other thin-films such as CdTe and A-Si used for thin film PV. Since solar modules will be required to operate for many tens of years this benefit allows CIGS solar modules to produce power closer to their original performance potential well into the future.

● Thirdly, CIGS is also amenable to automated production techniques. Today, thin-films enjoy low production costs that stem from combining automated production processes with low material costs. Unfortunately, today’s thin-film PV offerings also offer low conversion efficiencies when compared to silicon PV technologies. CIGS offers a viable opportunity to utilize automated manufacturing techniques while not sacrificing PV conversion potential.

● And lastly, thin film solar cells made from CIGS absorbers show great promise in achieving the highest thin-film conversion efficiencies approaching 20% and more. CIGS currently holds the world record for thin-film conversion efficiency at 19.9%. This may make CIGS one of the only truly viable thin-film candidates to compete with silicon.
