The potential of thermophotovoltaic heat recovery for the UK industry

Abstract: SYNOPSIS Thermophotovoltaics (TPV) is the use of the photovoltaic effect to generate electricity from a high-temperature thermal source. This paper aims to provide an overview of heat recovery by TPV from industrial high-temperature processes. The paper reviews the relevant facts about TPV technology and the high-temperature industry and identifies three principle locations for TPV heat recovery. For each location, one example process is assessed in terms of applicability of TPV, impact on the existing process and power scale. Knowledge of these factors should contribute to the design of an optimum TPV system. The paper estimates the range of possible energy savings and reductions of CO, emissions using TPV in the high-temperature industry.

Heat Transfer Modelling of Glass Media within TPV Systems

Abstract: Understanding and optimisation of heat transfer, and in particular radiative heat transfer in terms of spectral, angular and spatial radiation distributions is important to achieve high system efficiencies and high electrical power densities for thermophtovoltaics (TPV). This work reviews heat transfer models and uses the Discrete Ordinates method. Firstly one‐dimensional heat transfer in fused silica (quartz glass) shields was examined for the common arrangement, radiator‐air‐glass‐air‐PV cell. It has been concluded that an alternative arrangement radiator‐glass‐air‐PV cell with increased thickness of fused silica should have advantages in terms of improved transmission of convertible radiation and enhanced suppression of non‐convertible radiation.
