The bandgap of a solar silicon wafer is determined by measuring the energy difference between the valence band and the conduction band of the material. This can be done through various techniques, such as optical absorption spectroscopy or photoluminescence measurements. By analyzing the absorption or emission of light at different wavelengths, the bandgap energy can be accurately determined, providing crucial information for optimizing solar cell performance.

The bandgap of a solar silicon wafer is determined through various experimental techniques, such as photoluminescence spectroscopy or optical absorption measurements. These methods involve shining light of different wavelengths onto the wafer and measuring the corresponding response, which helps determine the energy difference between the valence and conduction bands, known as the bandgap.
