Stabila organiska transportlager för hållbara perovskitsolceller

Metal halide perovskites have shown great promise as photovoltaic materials with special properties and unique applications.

The main challenge is inferior stability against moisture and heat in state-of-the-art devices, related to the complicated compositions in the final organic charge transport layer.

Based on the achievements from my VR starting grant, we have made a significant breakthrough by developing a clean and effective doping strategy for organic transport layers, that delivers devices with the highest efficiency and the best moisture stability up to now (PCT patent application is ongoing).

These findings represent an excellent starting point that allows us to further tackle the thermal stability issues of organic transport layers in perovskite devices, which is critical for practical applications.

The expected achievements in this project could potentially be a game-changer for doped organic semiconductor films beyond the current limitation.

In addition, we will apply the thermally stable organic transport layers to fabricate various perovskite-based solar cells with high efficiency and durability beyond the state-of-the-art, thus bringing perovskite techniques closer to reality and contributing to sustainable energy growth in the long term.

Moreover, the fundamental understandings in this project are expected to provide new insights on doped organic semiconductors for various optoelectronic devices.
