XsunX Announces Improved Production Efficiencies

Aliso Viejo, CA, June 13, 2005 –XsunX, Inc. (OTCBB: XSNX), developer of Power Glass™ -- an innovative solar technology that allows glass windows to produce electricity from the power of the sun, released information today on the benefits of its recent success in the development of more efficient manufacturing techniques. This development allowed the Company to produce its first transparent solar cell on inexpensive thin-film plastic.

XsunX is developing Power Glass transparent solar cells on Polyethylenenapthalate (PEN) and Polyethylene Terphtalate (PET) plastics. The advantage in the use of PEN and PET is that these plastics are significantly less expensive – ranging between $.40 and $1.10 U.S. per square meter. To use these films, XsunX has had to develop ways of building solar cells at much lower temperatures than used in other solar cell manufacturing techniques.

For the sake of comparison, DuPont (NYSE:DD) manufactures a popular thin-film plastic product called Kapton. Kapton is widely used in the manufacture of thin-film solar cells due to its ability to resist more than double the heat as PEN and PET based plastics. However, this feature does not come without added cost as Kapton is about $11 per square meter.

XsunX’s believes that the use of films such as PEN and PET that are between 900% and 3000% cheaper than DuPont’s Kapton or other similar polyimide based films will provide a lower production line price-point and a competitive advantage to manufacturers that use Power Glass in their products.

The Company’s low temperature processing capabilities have been achieved through incremental process development under the watchful eye of Dr. Arun Madan, Chairman of the XsunX Scientific Advisory Board and founder of MVSystems, Inc. “We believe that the use of PET and PEN plastics to produce rolls of true thin-film transparent solar cells may represent a high degree of commercial viability to the multi-billion dollar glass and high performance coatings industry. We are committed to innovation and continue our efforts to bring product to market as quickly as possible,” said Dr. Arun Madan, Chairman Scientific Advisory Board and director of XsunX research.

About XsunX

XsunX, Inc. is developing Power Glass™ – an innovative solar technology that allows glass windows to produce electricity from the power of the sun. This means that inhabitants of buildings that have Power Glass™ films integrated into the skin of the building will be able to continue to view the great outdoors – as if they were looking through conventional glass windows. The difference is that these windows will now produce electricity to use to offset dependency on local utility supplied power and increase overall building operational efficiencies. This use of photovoltaics in building materials is a growing market opportunity referred to as Building Integrated Photovoltaics or “BIPV”. XsunX intends to become a recognized leader in the Building Integrated Photovoltaics industry. The Company plans to market the XsunX Power Glass™ solar cell structure and manufacturing process as a competitive alternative to non-energy producing coatings and glazing for applications in the worldwide architectural glass, optical film, and plastics markets.
