California Inventors Develop AC Solar Power Apparatus

Alexandria, Virginia [] David K. Fork of Los Altos, California, and Koenraad F. Van Schuylenbergh, of Sunnyvale, have developed solar cells that convert solar energy to alternating current (AC) electrical energy. According to the U.S. Patent & Trademark Office: “An AC solar power apparatus includes a photovoltaic cell and a circuit or device for causing a signal generated by the photovoltaic cell to oscillate in a negative differential resistance range, thereby producing an AC output voltage.”
