Title: The Innovative Contributions of Andrew Espenlaub

Introduction

Andrew Espenlaub is a notable inventor based in Albuquerque, NM (US). He has made significant contributions to the field of solar technology, particularly through his work on multijunction solar cells. With a total of 3 patents, Espenlaub's innovations are paving the way for advancements in renewable energy.

Latest Patents

Espenlaub's latest patents focus on multijunction solar cells. The first patent describes a multijunction solar cell that includes an upper first solar subcell with emitter and base layers forming a photoelectric junction. This subcell is complemented by a second solar subcell positioned beneath it, also featuring an emitter and base layers that create a photoelectric junction. Additionally, a third solar subcell is situated under the second subcell, maintaining the same structure. Notably, at least one of the base and emitter layers in these subcells has a graded band gap, which varies throughout the thickness of its active layer adjacent to the photoelectric junction. This graded band gap is designed to be in a range of 20 to 300 MeV less than the band gap in the active layer of both the emitter and base layers that are spaced away from the junction.

The second patent similarly outlines a multijunction solar cell with the same structural features, but with a key difference in the graded band gap. In this case, the graded band gap is greater than the band gap in the active layer of both the emitter and base layers, enhancing the efficiency of the solar cell.
