Description/Abstract

This paper discusses the various attempts to obtain the efficiencies of ideal solar cell by thermodynamic methods. The different methods that are discussed include the Landsberg efficiency which is obtainable from a simple model depicting the solar cell as a heat engine. The Shockley-Queisser detailed balance methods is also outlined briefly. We show that the Shockley solar cell equation implies different types of losses (reversible and irreversible) in different parts of the I-V characteristic. The application of thermodynamics to photovoltaic energy conversion includes also the open circuit voltage which is copared with experiment.
