TL;DR: In this paper, the authors present a unique design strategy for a hybrid PV/thermal system that only has mild thermal coupling which can lead to enhanced efficiency, by creating a fluid filter that absorbs energy directly in the fluid below the band-gap and a PV cell with an active cooling strategy combined effrciencies greater than 38% can be achieved.
Abstract: Two methods often proposed for harnessing renewable energy, photovoltaics and solar thermal, both utilize the power of the sun. Each of these systems independently presets unique engineering challenges but when coupled together the challenge intensifies due to competing operating requirements. Recent research has demonstrated these hybrid systems for low-temperature applications but there exists limited studies at higher concentration ratios, and thus higher temperatures. What these studies have shown is that keeping the photovoltaic (PV) cell temperature low keeps the overall system efficiency relatively high but results in low efficiencies from the thermal system. This study presents a unique design strategy for a hybrid PV/thermal system that only has mild thermal coupling which can lead to enhanced efficiency. By creating a fluid filter that absorbs energy directly in the fluid below the band-gap and a PV cell with an active cooling strategy combined effrciencies greater than 38% can be achieved.

TL;DR: In this article, the authors investigate a solar thermal receiver design that utilizes aerogels to suppress radiation losses, boosting the efficiency of solar thermal conversion. And they predict that receivers using aerogel-based receivers could be more efficient than vacuum-gap receivers over a wide range of operating temperatures and optical concentrations.
