Polarization Dependence of Water Adsorption to CHNHPbI (001) Surfaces
Nathan Z. Koocher, Diomedes Saldana-Greco, Fenggong Wang +2
The instability of organometal halide perovskites when in contact with water is a serious challenge to their feasibility as solar cell materials. Although studies of moisture expos…
First-Principles Calculation of the Bulk Photovoltaic Effect in KNbO and (K,Ba)(Ni,Nb)O
Fenggong Wang, Andrew M. Rappe
The connection between noncentrosymmetric materials' structure, electronic structure, and bulk photovoltaic performance remains not well understood. In particular, it is still uncl…
Bulk photovoltaic effect enhancement via electrostatic control in layered ferroelectrics
Fenggong Wang, Steve M. Young, Fan Zheng +2
The correlation between the shift current mechanism for the bulk photovoltaic effect (BPVE) and the structural and electronic properties of ferroelectric perovskite oxides is not w…
First-principles calculation of bulk photovoltaic effect in CHNHPbI and CHNHPbICl
Fan Zheng, Hiroyuki Takenaka, Fenggong Wang +2
Hybrid halide perovskites exhibit nearly 20% power conversion efficiency, but the origin of their high efficiency is still unknown. Here, we compute the shift current, a dominant m…
