Title: The Innovations of Andreas Kraenzl in Bifacial Solar Cell Technology

Introduction

Andreas Kraenzl, a prominent inventor based in Radolfzell, Germany, has made significant strides in the field of solar energy technology. With a total of two patented innovations under his belt, Kraenzl focuses on enhancing the efficiency and cost-effectiveness of solar cell manufacturing.

Latest Patents

Kraenzl's latest patents revolve around bifacial solar cells, offering innovative manufacturing processes. The first patent details a bifacial solar cell (BSC) with back surface doping. This simplified manufacturing process not only reduces costs but also includes key design features such as an active region on the front surface, created through a phosphorous diffusion step. The back surface is equipped with a doped region that matches the substrate's conductivity while boasting a higher doping level. Furthermore, contact grids are efficiently formed, potentially using screen printing techniques, with front junction isolation achieved via laser scribing.

His second patent focuses on bifacial solar cells with overlaid back grid surfaces. Similar to his first innovation, this BSC incorporates a simplified manufacturing process designed to lower production expenses. It features an active region on the front surface and requires dielectric layers to be deposited on both sides after removing specific phosphorous surface layers and isolating the front junction. Importantly, a metal grid is applied to the back surface before the deposition of the back surface dielectric, ensuring that the grid is aligned and alloyed during the contact firing process.
