Black perovksite solar cell achieves 20.25% efficiency
The Chinese Academy of Sciences has developed a black perovskite solar cell that reportedly achieved the the highest efficiency ever reported for PV devices built with this perovskite material and a dopant-free hole transport layer based on the P3HT polymer. The cell was also able to retain around 93% of its original efficiency after continuous illumination for 570 h.
Indium provides a boost to perovskite stability
Scientists at Rice University in the United States have found by strategically adding indium to an all-inorganic, lead-based perovskite, they can reduce the number of defects in the material and improve its efficiency, as well as providing a significant boost to stability.
Swimming electrons in perovskite nanocrystals
Research from Canada has revealed liquid-like lineshape dynamics in cesium-lead iodide perovskite nanocrystals. The findings could be used to produce cheaper and more efficient perovskite cells, researchers claim.
