BioSolar, developer of breakthrough products and materials that reduce the cost of photovoltaic (PV) solar modules, today announced that the company is developing BioSuperCap, a low cost polymer-based supercapacitor technology for reducing the cost of storing the energy of the sun.
BioSolar co-owns the patent-application for this supercapacitor technology with the University of California at Santa Barbara ("UCSB"), and is currently funding a sponsored research program to further its development. The lead inventors of the technology are UCSB professor Dr. Alan Heeger, the recipient of a Nobel Prize in 2000 for the discovery and development of conductive polymers, and Dr. David Vonlanthen, a post-doctoral researcher at UCSB.
According to the latest edition of NPD Solarbuzz Marketbuzz, the solar photovoltaic (PV) industry is predicted to experience rapid growth over the next five years, with up to 100 gigawatts (GW) of annual installations, growing to $50 billion per year of PV module revenue by 2018. With all of these solar panels being installed, there is still one major challenge that prevents solar from being a primary and reliable source of power -- the sun does not shine at night.

This switch causes sudden spikes in power demand on the grid and creates havoc at the local power company because the grid is not designed to respond to rapid demand changes. The key to solving this problem is efficient solar energy storage systems that can be charged and discharged rapidly, day in and day out. This will time-shift daytime solar energy for nighttime use with minimal reliance on the power grid.
Dr. David Lee, the company's CEO said, "Existing battery technologies, such as lithium-ion batteries, are good for longer-term energy storage, but cannot be charged or discharged rapidly. This limits the use of batteries to power backup applications. Supercapacitors, on the other hand, can be charged and discharged hundreds of times faster than batteries. Unfortunately, conventional supercapacitors are very expensive and store less energy. BioSuperCap is designed to be a low cost and high energy supercapacitor. By integrating BioSuperCap as the front-end to battery banks, fewer batteries can be used, and daytime solar energy can be quickly and cost-effectively stored for nighttime use at a substantially lower cost. This potentially game-changing technology will allow users of solar energy systems to reduce their dependence or go completely off the electric utility power grid."
