Updated:
Organic-inorganic hybrid solar cells offer remarkable power conversion efficiencies above 25%, but their widespread adoption faces a critical hurdle: moisture sensitivity. When exposed to relative humidity above 50%, these devices typically show degradation within hours, with performance dropping significantly as water molecules trigger decomposition of the active layer materials.
The fundamental challenge lies in developing encapsulation strategies that maintain optical transparency and electrical conductivity while providing robust protection against moisture ingress.
This page brings together solutions from recent research—including parylene composite encapsulation layers, quasi-two-dimensional fluorinated structures, and multi-layer protective architectures with integrated barrier films. These and other approaches focus on practical methods to achieve both high efficiency and long-term stability under real-world environmental conditions.
