Localization of Current Flow in Thermophotovoltaic Converters Based on InAsSbP/InAs Double Heterostructures

摘要

The electrical performance of thermophotovoltaic converters with a flip-chip design based on p-InAsSbP/n-InAs/n-InAsSbP double heterostructures with the substrate completely or partially removed is examined. The influence of resistance of different parts of the structure on the spatial distribution of current density in the active region is revealed, and the conditions for maximizing the efficiency of photocurrent collection and minimizing confluence are determined.
