Photovoltaic panel designer BioSolar Inc. announced on Thursday a partnership with UC Santa Barbara to develop a new method of storing the energy of the sun. The partnership will seek to develop what is being called the BioSuperCap, a low cost polymer-based technology that speeds the charging and discharging of existing batteries and reduces overall costs. The small Santa Clarita firm, which has been developing lower-cost photovoltaic solar panels, co-owns the patent application with the school. The lead inventors of the technology are UCSB professor Alan Heeger, the recipient of a Nobel Prize in 2000 for the discovery and development of conductive polymers, and David Vonlanthen, a post-doctoral researcher at UCSB. “Fewer batteries can be used, and daytime solar energy can be quickly and cost-effectively stored for nighttime use at a substantially lower cost,” said BioSolar Chief Executive David Lee. Shares rose by 5 cents, or about 33 percent, to close at 20 cents on the OTC Bulletin Board.

A Nasdaq hearing panel on Wednesday extended the deadline from Sept. 12. The delays in filing the reports stems from the sudden resignation last fall of then-Chief Executive Walt Alston, which led to an accounting review by the Board of Director’s audit committee. “We are continuing to devote substantial resources to complete and file the quarterly reports and expect to become current before the November date set by the panel,” said acting CFO Brent Novak, in a prepared statement.
