Modeling direct conversion of the concentrated light energy to electricity in a photoplasma

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.
