Accounting for Interference, Scattering, and Electrode Absorption to Make Accurate Internal Quantum Efficiency Measurements in Organic and Other Thin Solar Cells

Accurately measuring internal quantum efficiency requires knowledge of absorption in the active layer of a solar cell. The experimentally accessible total absorption includes significant contributions from the electrodes and other non‐active layers. We suggest a straightforward method for calculatin...

Description
Summary:	Accurately measuring internal quantum efficiency requires knowledge of absorption in the active layer of a solar cell. The experimentally accessible total absorption includes significant contributions from the electrodes and other non‐active layers. We suggest a straightforward method for calculating the active layer contribution that minimizes error by subtracting optically‐modeled electrode absorption from experimentally measured total absorption.
