Dataset to accompany publication "Best practices in measuring absorption at the macro- and microscale"

This dataset accompanies the publication "Best practices in measuring absorption at the macro- and microscale" published in APL Photonics. The data can be used to reproduce original plots in figures 1-4 in the main text and all original plots in the supporting information (noting several plots are reproductions of others' works, as noted in the text). This data was generated through a microscale absorption meaurements and . All files are in .csv and easily readable. 

The abstract for the associated paper is as follows:

The fraction of light absorbed in a material is a key parameter for a wide range of optoelectronic and energy devices, including solar cells, light emitting diodes and photo(electro)chemical devices. It can reveal detailed performance information and establish a material’s theoretical efficiency limits. However, measuring absorption accurately is challenging, especially due to scattering effects at macroscale and achieving perpendicular illumination over a small area at the microscale. In this tutorial we present concepts and best practices in measuring absorption at both the macro- and micro-scale. We also give examples of using absorption to reveal critical optoelectronic information in energy devices. This work aims at standardising the recording of absorption measurements across a number of fields, allowing for improved microscale understanding of a wide range of samples.

材料对光的吸收占比是诸多光电子与能源器件的核心参数，涵盖太阳能电池、发光二极管以及光（电）化学器件。该参数可揭示器件的详细性能信息，并可用于确定材料的理论效率极限。然而，精准测量吸收量颇具挑战，尤其受限于宏观尺度下的散射效应，以及微尺度下难以实现小面积垂直照明的问题。本文阐述了宏尺度与微尺度吸收测量的相关概念及最佳实践方案，并通过实例展示了如何利用吸收测量揭示能源器件的关键光电子学信息。本研究旨在统一多领域内吸收测量的记录规范，从而推动对各类样品的微尺度认知水平提升。
