SUMMARY
The discussion focuses on the relationship between light intensity and current generated in solar cells, specifically in the context of a solar cell characterization project. The user is attempting to correlate light intensity from a solar simulator with the electrical parameters of the solar cell, such as Isc (short-circuit current) and Voc (open-circuit voltage). Key concepts mentioned include Quantum Efficiency (EQE and IQE), which relate the number of photons incident on the solar cell to the current produced. The user suggests a formula to convert light intensity to the number of photons using the equation: number of photons/area = Intensity/(h * frequency).
