A polymer tandem solar cell with 10.6% power conversion efficiency

Nature Communications, 2013
An effective way to improve polymer solar cell efficiency is to use a tandem structure, as a broader part of the spectrum of solar radiation is used and the thermalization loss of photon energy is minimized.

Review of supercritical carbon dioxide (sCO2) technologies for high-grade waste heat to power conversion

SN Applied Sciences, 2020
In the European Industry, 275 TWh of thermal energy is rejected into the environment at temperatures beyond 300 °C. To recover some of this wasted energy, bottoming thermodynamic cycles using supercritical carbon dioxide (sCO2) as working fluid are a ...
