It performs extensive perovskite-based R&D (as well as on OPVs and other emerging technologies) and is seeking to make perovskite solar cells a viable technology by focusing on its efficiency, stability, and scaling. NREL's research is currently focused on several areas, including ultrahigh-efficiency and low-cost polycrystalline halide perovskite thin-film solar cells; electronic energy level alignment at the carbon nanotube/organic metal halide perovskite interface; and stable perovskite solar cells via chemical vapor deposition.
NREL's expertise is in the following areas related to perovskite PV:
- Basic materials characterization
- Fundamental photophysics, photochemistry, and exciton/charge-carrier dynamics
- Interfacial energy alignment and charge-transfer (carrier-collection) processes
- Structural and composition characterization
- Material and compositional engineering for improved stability
- High-efficiency solar cell fabrication with device performance and stability testing
- Scale-up, printing, slot-die coating, and roll-to-roll manufacturing.
