A team at Fraunhofer ISE has created new imaging methods to measure losses in individual sub-cells of multi-junction solar cells based on perovskite-silicon and perovskite-perovskite-silicon ...
Single junction type (a) and the proposed double junction type (b) solar cells are compared with the conventional TANDEM type (c) and the proposed face-to-face type (d) multi-junction connections. A ...
