The interlayer method: A universal tool for energy level alignment tuning at inorganic/organic semiconductor heterojunctions
T. Schultz et al. | Adv. Funct. Mater. 31 (2021)
Here, a universal approach to adjust the offset between the energy levels at inorganic/organic semiconductor interfaces is demonstrated. By inserting strong electron donor or acceptor molecules between two semiconductors, the level alignment can be tuned over an unprecedented range of 1.8 eV.
Position-locking of volatile reaction products by atmosphere and capping layers slows down photodecomposition of methylammonium lead triiodide perovskite
F. Zu et al. | RSC Adv. 10 (2020)
The remarkable progress of metal halide perovskites in photovoltaics has led to the power conversion efficiency approaching 26%. However, practical applications of perovskite-based solar cells are challenged by the stability issues, of which the most critical one is photo-induced degradation. Bare...
Excited-State Charge Transfer Enabling MoS₂/Phthalocyanine Photodetectors with Extended Spectral Sensitivity
N. Mutz et al. | J. Phys. Chem. C 124 (2020)
In this paper we explored the interface between the transition metal dichalcogenide MoS2 and the non-metallated molecule phthalocyanine H2Pc. By measuring UPS and inverse PES of the bare MoS2 and in combination with a thin layer of H2Pc, a type II energy level alignment between MoS2 and H2Pc could...
