Based on analysis of the frequency distribution of radiation from the sun, it can be considered to-be emitting radiant energy with a Stefan-Boltzmann distribution at a temperature of 6000 K. Estimate the maximum efficiency with which this radiant energy can.be converted io electrical (or mechanical) energy using solar cells (commonly called photovoltaic cells). For this analysis assume that the solar cell is operating in steady state and is receiving radiant energy, that its surface temperature is 300 K, and that it is losing heat by conduct, ion to the environment
