BioSolar advised that its BioBacksheet has been granted provisional relative thermal index (RTI) recognition by Underwriters Laboratories (UL). The company first received UL materials certification for its technology in February and since that time has seen the UL conduct long-term thermal stability testing on the BioBacksheet.

The official provisional RTI designation by UL should permit solar panel manufacturers to use the BioBacksheet in the production of the panels towards the achievement of full UL certification, which the company “expects to be merely a procedural matter.”

Dr. David Lee, the company’s CEO, commented, “This is a defining moment for BioSolar. By receiving the official provisional RTI designation from UL, we have completed the final product development milestone for BioBacksheet. I am pleased to report that we are finally ready to accept commercial orders. During the past two years, we have worked closely with several key solar manufacturers that will now be sending their panel to UL for final certification. Once their revised panels are re-certified with BioBacksheet, these customers will be able to sell their solar panels in the general marketplace.”
