Electron blocking for 18.5%-efficient carbon-electrode perovskite solar cell Scientists in Germany and Switzerland have developed a perovskite solar cell with a carbon electrode that achieved 18.5% efficiency. It also retained 82% of this after 500 hours of continuous illumination. While a long way behind what has been achieved with other perovskite solar devices, the cell is produced via all low-temperature processes that could likely be scaled into low-cost, large-scale manufacturing – making the approach one worth pursuing further.
