Swiss scientists have built a 4T tandem perovskite/CIGS mini-panel with a geometric fill factor of over 93%. It combines a 10.8%-efficient mini perovskite module and a 15.1%-efficient CIGS device.
GIST researchers have developed a perovskite mini-module with 22.56% efficiency by improving the SnOâ‚‚ electron transport layer with PEI, reducing defects and electron loss. The module retained 94% of ...
