2021 Joule (IF 41.248), LD MHP Film Enhances Mechanical Reliability of Flexible PSC

Top-Notch Due to It’s Precision!

  Joule (IF 41.248) published a study on flexible perovskites. Researchers use low-dimensional (LD) metal-halide perovskite (MHP) film coatings to improve efficiency, stability, and mechanical reliability at the same time.

  Perovskite solar cells (PSC) have made great progress in power conversion efficiency (PCE) and stability. Despite this, few people pay attention to mechanical reliability. Mechanical reliability is very important for flexible perovskite solar cells (flexible PSCs, f-PSCs). In this study, the researchers covered the 3D MHP light-absorbing film of f-PSC with a low-dimensional metal halide perovskite (LD MHP) film. Through the MHP film, the researchers enhanced photocarrier extraction, provided environmental protection, and “sealed” surface defects on the 3D MHP film, which also reduced the tendency to crack during bending.

  Through the quantum efficiency measurement system of Enlitech, the research results showed that the PCE (21.0%), operation stability (T90 = >800 h) and bending durability (T80 = 20,000 stretch bending cycles) of f-PSC had unprecedented improvements. In addition to the EQE (External Quantum Efficiency) spectrum analysis of solar cells, the quantum efficiency measurement system of Enlitech also provides Jsc (short-circuit current density) comparison for the short-circuit current of solar cells under the solar simulator, proving the authenticity of the experiment.
