Abstract
Perovskite-based photoactive devices, such as solar cells, include an insulating tunneling layer inserted between the perovskite photoactive material and the electron collection layer to reduce charge recombination and concomitantly provide water resistant properties to the device.
Claims28
A photoactive device, comprising:
- a first electrode layer;
- a second electrode layer;
- a perovskite material disposed between the first electrode layer and the second electrode layer;
- and
- an insulating layer disposed between the first electrode layer and the perovskite material.
2 more elements
A photoactive device, comprising:
