Accelerated scaling of open-air processed perovskite solar modules
Abstract/Contents
- Abstract
- Mechanical properties are excellent predictors for device resilience to environmental stressors that accelerate the evolution of internal defects and cause delamination and device failure in layered structures. The fundamental mechanical and material properties of perovskite photovoltaics (PV) are first investigated to gain insight on relevant degradation modes and failure mechanisms. Perovskites are identified as the most mechanically fragile solar technology, further complicating the prospect of commercial viability. The mechanical integrity and residual film stresses of perovskite materials are connected with device stability, and strategies are developed to improve the thermomechanical reliability of perovskite PV in order to inform design criteria for stable, large-area solar modules. This work demonstrates the first industrially relevant attempt to address both scalable and fast open-air PV module manufacturing for the perovskite layer at production speeds that are > 10 m/min for the perovskite absorber layer. By implementing demonstrated open-air, rapid spray processing techniques with improved thermomechanical reliability of the perovskite absorber material at the highest reported throughput of any solar technology, significant steps are made towards reductions in manufacturing costs necessary to provide a new low-cost PV process that can compete with incumbent Si-based PV.
