Perovskite Single-junction Solar Cells

Interface · SAM-based hole transporting layer · Bulk passivation

Advancing high-PCE, stable single-junction devices along engineering buried/top interfaces, developing SAM-based hole-transporting layers, and passivating bulk defects, which target non-radiative recombination and long-term operational stability of the black phase.

Halide Perovskites · Phase Stability

Engineering high-Br mixed-halide perovskites (Eg ≥ 1.6 eV) with suppressed phase segregation under prolonged illumination — a key stability bottleneck for tandem architectures.

All-Perovskite Tandem Devices

2-Terminal Monolithic Tandems · >28% PCE

Monolithic 2-terminal all-perovskite tandems coupling wide-Eg and narrow-Eg subcells via ALD and Sputtering tunneling recombination junctions (TRJ).

Operando Characterisation & Stability

ISOS Protocols · In-Situ Measurements

Real-time stability monitoring using custom-built operando/in-situ XRD/GIWAXS/PL/UV-Vis platforms under ISOS protocols (L-1, D-1, T-1); J-V, SPO, MPPT correlating structural evolution with device degradation pathways.
