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.
A new manufacturing process for 19.5% efficient perovskite solar cells
Researchers in China have proposed manufacturing perovskite cells using a pre-nucleation technique. Compared to traditional solvent dripping methods, the approach enables the creation of smaller crystallites in the perovskite films as uncontrolled crystallite growth affects the efficiency and durability of cells.
French scientists try to uncover the secrets of black perovskite
X-ray analysis is said to have solved the mystery of how to preserve optical absorption in perovskite layers. Researchers say the discovery could help stabilize the material and speed up the launch of a new ingredient for PV research.
