Title: Innovator Spotlight: Henry W. Brandhorst, Jr.
Introduction: Henry W. Brandhorst, Jr. is a notable inventor based in Berea, Ohio, who has made significant contributions to the field of solar energy technology. With a remarkable portfolio of five patents, his work emphasizes innovation in solar cell design and efficiency.
Latest Patents: Among his latest inventions, two notable patents stand out. The first is a thin, lightweight solar cell that leverages front contact metallization. In this design, both the front light-receiving surface of the solar cell and the opposing surface of the cover glass are recessed to allow for optimal metallization. This innovative approach ensures that the two surfaces meet flush, facilitating an optimum seal. The second patent pertains to a lithium counterdoped silicon solar cell. This invention improves the resistance of an n.sup.+ p boron doped silicon solar cell to radiation damage through the introduction of lithium counterdoping. Despite lithium being an n-dopant in silicon, the careful dosage maintains the p-type characteristics of the cell base. Lithium ions, implanted at approximately 50 keV, bedazzle the solar cell wafer, which is then annealed in a nitrogen atmosphere at 375 degrees Celsius for two hours.
Career Highlights: Throughout his industrial career, Henry W. Brandhorst, Jr. has been affiliated with significant organizations, including the United States of America, as represented by the Administrator and by the United States. His work has helped advance the realm of renewable energy and has fostered the development of innovative solar technologies.
