Fully printed carbon electrode perovskite solar cell achieves 19.2% efficiency

German scientists have fabricated a carbon electrode perovskite solar cell with a hole-transporting bilayer made of organic semiconductors instead of a conventional hole transport layer. They claim this approach improves the device’s fill factor and open-circuit voltage.

Ground mounted agrivoltaics have minimal impact on grassland carbon-water cycling

A US-Spanish research team studied the ecological effect of a solar photovoltaic array located on a managed grassland plot using a hydraulic and soil hydrology model and field measurements. They found minimal effect on the plants’ carbon-water cycling, which they attributed to plant photosynthetic traits changing to take advantage of the dynamic shading under the panels.

New study finds growing inequality in metal footprints of renewable power value chains

A US-Chinese research team has investigated the flow of iron, copper, aluminum, and other precious metals from source to end-use destination in the renewable energy infrastructure value chain. It found significant imbalances that can be attributed to the continuous outsourcing of metal demand for the renewable power sector to developing economies.
