Alumina oxide nanoparticles extend perovskite solar cell lifetime

Scientists in the U. K. have used alumina oxide in perovskite solar cells to achieve lifetimes exceeding 1,300 h under standards-based heat and humidity testing. Their analysis showed that a reference cell based on conjugated polyelectrolytes degraded in one-tenth the time. Scientists in the United Kingdom have used alumina oxide (Al2O3) nanoparticles (NPs) as an interfacial modifier at the hole transport layer (HTL) to increase the lifetime of perovskite solar cells. The researchers said that the alumina nanoparticles significantly enhanced the lifespan and stability as revealed in tests under ...
