Title: The Innovative Journey of Hans-Peter Sperlich

Introduction: Hans-Peter Sperlich, an accomplished inventor based in Dresden, Germany, has made significant contributions to the field of solar cell technology. With a total of eight patents to his name, his work focuses on enhancing the efficiency and production methods of crystalline solar cells.

Latest Patents: Among Hans-Peter’s latest innovations are two noteworthy patents. The first patent describes a crystalline solar cell that incorporates a transparent, conductive layer positioned between the front-side contacts. This design features a monofacial or bifacial crystalline solar cell, where a surface passivation layer is applied directly on the semiconductor interface. This is then covered with an optically opaque, electrically conductive material in specific lateral regions, while a transparent, conductive material is used exclusively in others. Notably, the method for producing this solar cell allows the application of the transparent layer only after the opaque contact has been established, preventing any potential issues during firing.

The second patent outlines a method for producing a solar cell with a heterojunction. This process involves layering an amorphous nano- and/or microcrystalline semiconductor on the front face of a crystalline substrate, establishing both front and rear surface field layers while ensuring efficient deposition of transparent dielectric layers. With this innovative approach, the efficiency and efficacy of solar cells are notably enhanced.
