Estimating Bandgap Energy of Nanoarchitectured and Conventional Materials for Solar Cell Application

Recognizing the need for versatile and user-friendly software capable of accurately deriving bandgap values from either measured or simulated absorbance data, we introduce a program developed in MATLAB employing the Tauc plot method. This program has been validated by analyzing conventional bulk semiconductors simulated using COMSOL Multiphysics. The resulting bandgaps agree remarkably within three significant figures with those from literature. Validating its accuracy, this indicates the program’s potential extension to novel materials and geometries.
