Developing Methods for Wet Chemical Etching of a Separation Mesa Structure during Creation of Multijunction Solar Cells
2019
The postgrowth processing of mesa structures for multijunction solar cells based on GaInP/GaInAs/Ge heterostructure has been studied. Methods of wet chemical and electrochemical etching are considered, and a technology of forming a separation mesa structure is proposed that ensures improved surface quality and profile of the side wall of a mesa for heterostructures with various compositions of layers.
