Jülich Researchers Increase Open-Circuit Voltage of Perovskite Solar Cells

Jülich, 28 January 2019 – Scientists from Forschungszentrum Jülich have succeeded in raising the open-circuit voltage of perovskite solar cells to a record value of 1.26 volts. The voltage is seen as the key to improving the cells’ efficiency. It shows the number of electrical charge carriers present in the cell when light falls on it, and is thus directly proportional to the cell’s achievable performance.
