Lecture

Optical absorption measurements

Description

This lecture on Optical absorption measurements covers the theory, implementation, and applications of optical absorption. It explains how light interacts with charged species like protons and electrons, leading to absorption. The lecture delves into the measurement techniques, such as measuring the number of photons not absorbed, applications in sight, biological cells, chemical reactions, and solar cell potential. It also discusses the limitations of experiments, equipment required for accurate measurements, and the Beer-Lambert Law. The lecture explores topics like identifying chemicals in solutions, monitoring chemical reactions quantitatively, calculating material thicknesses, and measuring absorption for maximum solar cell efficiency.
