The scientists developed the panel with a quaternary approach by using a commercially available polymer, PM6, and a fullerene electron acceptor known as PC71BM, which is commonly used in the most efficient organic photovoltaic devices.
Since solar thermal power generation is a mature technology and has been widely applied, modifying solar thermal power generation devices for PTC processes is a feasible solution, which can integrate with heat collection and meet the temperature requirement for the PTC processes in the meantime.
Figure 12b shows the photothermal device based on a chromium film, which could heat CuO x /ZnO/Al 2 O 3 nanosheets to around 300 °C under one standard solar irradiation and generate hydrogen from efficient water-gas shift reaction (WGSR).
