Title: Inventor Spotlight: Randolph J Dziendziel
Introduction
Randolph J Dziendziel, based in Middle Grove, NY, is an innovative inventor with a focus on energy conversion systems. With a total of three patents to his name, his work significantly contributes to the field of thermophotovoltaic (TPV) energy technologies.
Latest Patents
One of Dziendziel's most notable inventions is the "Tandem filters using frequency selective surfaces for enhanced conversion efficiency in a thermophotovoltaic energy conversion system." This invention addresses the challenge of minimizing parasitic absorption of below bandgap energy in TPV systems. By utilizing a novel combination of front surface filters, Dziendziel's invention enhances TPV conversion efficiency, effectively reflecting below bandgap energy while transmitting a high percentage of useful above bandgap energy. The design integrates a frequency selective surface, which ensures high transmission rates for above bandgap energy while reflecting long wavelengths below the bandgap. An interference filter complements this setup, maintaining high transmission and reflecting short wavelengths below the bandgap, resulting in a sharp transition from high transmission to high reflection.
