In the commented paper, the optical path length factor Z0 is evaluated in a high-performance Si solar cell by using a reported procedure, which requires a previous determination of the slope 1/WIQE and the y-intercept 1η ′c of the linear fit to inverse internal quantum efficiency 1/IQE versus absorption depth 1/α, where α is the absorption coefficient. The authors of the commented paper calculate values of WIQE and η′c that are inconsistent with their data and graphs. In this comment, self-consistent values of WIQE and η′c are derived that are congruent with the data.
