Newsletter: Update to Co-Evaporation Progress, Industry Insights to Best CIGS Processing Techniques, and XsunX Sales Development Efforts

Technology and Corporate Development Progress Update

To Our Valued Shareholders


As XsunX continues development of its cross-industry CIGS technology, we wanted to provide an update not only on the progress in the laboratory but in other areas less explored in these newsletters, including sales efforts and technologies being developed to support our turn-key business model.


On the laboratory front, it has only been a month since we completed the assembly of the co-evaporation chamber and began calibration of the system.  With a large part of the calibration effort behind us we were able to recently begin co-evaporation of our cross-industry CIGS cell structure with the focus on continuous process testing, refinement, and improvement of the CIGS layer. In addition, last week we began the combination and refinement of the sputtering and co-evaporation processes necessary to produce complete CIGS devices. The combination of these different deposition techniques used to produce individual CIGS solar cells is the key differentiator to XsunX's CIGSolarTM strategy.


With these important processes underway, we are again moving incrementally toward the production of full-size CIGSolarTM solar cells that combine both sputtering and high temperature co-evaporation deposition methods - a coupling seen by many experts as the optimal path toward reaching the highest conversion efficiencies possible in solar PV development.


A July 26, 2010 article published in Compound Semiconductor outlines recent work published by scientists at Johannes Gutenberg University Mainz pointing to the use of high temperature processes to combine the copper, indium, gallium, and diselenide to form the optimal CIGS solar cell. The technical article outlines findings, "that, indeed, the efficiency of the cells increases if the CIGS layer is created at a higher temperature," a focus of the XsunX CIGSolarTM co-evaporation process.


Being developed in tandem are the techniques for the use of this unique technology as a replacement for silicon solar cells. XsunX understands that a viable replacement for silicon cells must be a robust end-to-end technology. To realize this turn-key solution, we have been working to further refine the techniques for placing the electrical collection grids on each cell and the interconnection, or tabbing and stringing, methods necessary to incorporate our CIGSolarTM cells into solar modules.


As progress in the lab continues, we have increased our business development efforts as well in order to attract new potential licensees. Our focus has been to offer JV manufacturing licenses under which we plan to work through existing solar companies to introduce our CIGSolarTM technology into multiple markets. In addition, we've been furthering sales discussions and negotiations with customers we've already brought into the developing sales channel. Our goal is to simultaneously mature the development of our technology and our sales channel to allow us to enter into license agreements by year's end. While there is still a great deal of work to accomplish we believe that this goal may still be attainable.


Thank you for your continued support of our company. As always, if you have any questions in the meantime, please contact our Investor Relations desk at [email protected] or (888) 797-4527.
