Solar Panel Efficiency

This lecture explores the efficiency of a satellite's solar panel in collecting photons, calculating the necessary surface area and the force exerted by the absorbed photons. By considering the solar constant, wavelength, and Planck's formula, the instructor demonstrates how to determine the surface area required to collect one mole of photons per minute and calculates the force exerted on the panel when all photons are absorbed. Different approaches, such as calculating power through intensity and surface area or through momentum transfer, are discussed to provide a comprehensive understanding of the topic.
