Abstract

A highly reflective rear mirror can increase the efficiency of thermophotovoltaics through regeneration of unused photons. Based on this concept, we recently demonstrated a record 29.1% thermophotovoltaic device efficiency. We have also identified the challenges as we aim towards 50% thermophotovoltaic efficiency.
