Abstract

A model of photovoltaic effect in photoplasma of lithium vapor under the action of concentrated resonant radiation is considered. This paper presents calculation of Volt–Ampere characteristics and estimation of the efficiency of a converter with spherical electrodes. It has been shown that the distance between the focused light volume and the electrodes as well as the electrode areas strongly affect the system efficiency. A model of photoplasma under diffusion conditions is developed. Estimations of the energy losses in the photoelectric converter are obtained.
