Photodiodes based on organic and emerging semiconductor materials have demonstrated high potential for optical sensing in biomedicine, imaging applications, and light-based data transmission. During the last decade, concerns have arisen regarding the reliable reporting of the device performance, especially under low illumination conditions. This work addresses these concerns and provides a robust framework for measuring and reporting standardized photodetection metrics. We have developed a measurement setup including a highly sensitive electrometer, calibrated optical filters, and light sources with narrowband emission spectra. For operation of the setup, we provide open-source Python scripts and outline protocols suitable for accurate characterization of steady-state photodetecting metrics.
