Perovskite solar cell with 23.93% efficiency via new moisture treatment
Scientists from China developed a controllable moisture treatment for perovskite films that is reportedly able to promote the mass transportation of organic salts. The films were used to build a 0.2 cm2 perovskite solar cell that was able to retain 80% of its initial efficiency after 1200 h.
PV-driven aerator for shrimp aquaculture
The aerator consists of a 200 W solar panel, an aerator frame, an eight-leaf windmill for paddling water and restoring oxygen levels, a DC motor working as a driving wheel, a buoy as a component lifter, and a box panel as a protective tool that uses the electricity network.
Perovskite-silicon tandem single-cell solar module with 26.2% efficiency
Researchers in Saudi Arabia claim to have reduced cell-to-module losses in tandem perovskite silicon photovoltaic devices through an optical redesign of the module through refractive-index engineering. They built a monolithic perovskite-silicon tandem mini-module with a power conversion efficiency of 26.2%.
