Explicit solvation accounts for solvent chemical interactions with the electrode and adsorbed species, but including more than the first solvation shell typically requires expensive molecular dynamics simulations to sample the large thermodynamic phase space of solvent configurations. Ab initio molecular dynamics of electrolytes are particularly challenging due to the need for long timescale and large simulation cells to capture statistically significant numbers of ions. These challenges are substantially magnified when combined with GW calculations due to its significantly higher computational expense as compared to semi-local generalizedgradient approximation (GGA) calculations. Nevertheless, this approach has been used to predict the G 0 W 0 @(GGA/hybrid) photoelectron spectra of NaCl + 52 H 2 O, 17 G 0 W 0 @(PBE, r 2 SCAN, PBE0) IPs of solvated transition metal ions, and stochastic G 0 W 0 @PBE photoemission spectra of organic molecules. Implicit solvation approaches, which replace explicit solvent configurations with polarizable continua or liquid density distributions, are more computationally expedient and widely applied in conjunction with DFT in first-principles electrochemistry. These models bypass the phase-space sampling issue and capture the impact of the liquid in a single electronic structure calculation, which is particularly attractive for combining with high-fidelity electronic structure methods such as GW. Some of the ingredients for solvated GW emerged in explorations of electrochemical systems with GW using solvated-DFT starting points, and in dielectric screening models to account for substrate effects in GW calculations of low-dimensional materials. Recent studies have integrated solvation models in the DFT starting point and as a dielectric profile modifying either the static dielectric matrix, Coulomb potential, or static COH-SEX self-energy. However, the impact of dynamic screening by the solvent in GW calculations has not yet been explored, and solvated GW is not yet available in the widely-applied first-principles electrochemistry tools.
