EML 4550/5451 Energy Conversion Systems for Sustainability Homework # 6 Due: Tuesday October 17, 2006 CLEARLY STATE ANY ASSUMPTIONS Topic: Design of a photovoltaic converter We wish to design a solar power plant that produces 2500 watts. The energy of the photons and their density are given as Φ = 0.059 W/cm 2 ; ε av = 1.25 eV; N ph = 4.8 x 10 17 No./sec-cm 2 . Assume that the converter units are p-n junctions made from silicon with the following
