Measured and Calculated ηph
ηph versus (A) Tpulse at I = 1,000 μE/(m2-s) (at the optimal Tdark) and Npool = 7, τdel = 10 ms, A = 1 nm2 for model calculations; (B) I for Tpulse = 10 ms, Tdark = 290 ms; and (C) I for Tpulse = 150 ms, Tdark = 250 ms. Vertical bars indicate ±1 standard deviation about the average for the experimental data, with each measured point coming from 8 replications.
