Researchers at the Australian National University are working with a new Australian company, Spark Solar Australia and Braggone Oy on a three-year project to develop spray-on solar panels that are both cheap and highly efficient.

Traditionally, solar cells are made of silicon coated with a thin layer of anti-reflective silicon nitrate. The cells are expensive to produce because they are made in a vacuum and creating a vacuum like situation doesn’t come cheap. If this step can be skipped from the solar cell production, price tags can be brought down considerably. The new method uses a spray-on hydrogen film and spray-on anti-reflective film. In this spray-on method vacuums are not needed. The cells travel along a conveyor belt where the films are sprayed on. The simplified process could trim down about $5 million in capital equipment costs per medium-sized factory. The manufacturer can save and produce solar cells at a much cheaper rate. Testing of the process is now taking place at the ANU, and the technology should be available toward the end of 2011.

Spark Solar will establish a $70 million high-tech solar cell factory in the Australian Capital Territory (ACT). Their main objective will be to initiate solar cell production in 2010. The factory will take a daunting task of producing 19 million solar cells a year. That volume of production will be enough to power 20,000 homes, along with exports worth more than $400 million to Europe’s booming solar markets. Presently the global market for solar cells is growing at a faster rate than markets for mobile phones, digital cameras and laptops.
