XsunX Achieves Improved Solar Cell Efficiency

Aliso Viejo, CA, February 14, 2006 – XsunX, Inc. (OTCBB: XSNX), developer of Power Glass™ -- an innovative solar technology that is intended to allow glass windows to produce electricity from the power of the sun, announced today that continued product development success has produced improved solar cell efficiencies. This represents a milestone for the Company in efforts under its Phase III development program to perfect a scalable manufacturing method for large area solar cells on inexpensive thin film plastics. 

The efficiency improvements were the result of efforts to increase the band gap properties of the cell structure. An increase to the band gap properties allows the cell to capture and convert a larger portion of the available solar energy into electricity. Another area of improvement associated with this effort was the increase of the open circuit voltage capabilities of the solar cell structure. Combined these improvements produced thinner more transparent cell structures than previous base lines, and conversion efficiencies of 5% on glass in lab tests. The Company is now working to transfer these results into its large area thin film cells on flexible plastics.

“While we are working to complete a scalable manufacturing process for Power Glass films we have continued to work on efficiency improvements of the solar cell itself,” stated Tom Djokovich, CEO of XsunX. “An improvement to the band gap properties of solar cell materials is an area of industry wide effort. Improved band gaps allow the same materials to produce more power. This translates into low per watt costs and is why there is so much work being done in this area. In making the cell thinner, more transparent, and more efficient may allow us to use these gains to help improve yield and throughput under mass production conditions,” concluded Mr. Djokovich.

The core design of the Company’s manufacturing process is based on a patented multi-chamber cluster tool approach using cassettes to control rolls of thin plastic films. The rolls of material (transparent plastic films) are loaded into the cassettes and robotically moved between chambers or stations. Layers of transparent semiconductor and conducting materials are deposited onto the plastics in a manner which prevents cross contamination between chambers to achieve high performance, semi-transparent, large area solar cell devices.

About XsunX

Based in Aliso Viejo, California, XsunX is the developer of Power Glass - an innovative solar technology that allows glass windows to produce electricity from the power of the sun. This proprietary process is intended to allow manufacturers to apply a transparent and photovoltaic glazing to glass and other transparent substrates. When XsunX glazing is exposed to light, the light energy is converted into electrical energy for use as a power source. XsunX believes that its solar electric glazing technology has a number of major market opportunities in the worldwide architectural glass, optical film and plastics markets.
