Analytical model of a plasma photoconverter

An analytical model of photovoltaic effect in plasma under conditions of nonuniform distribution of alkali vapors and buffer gas in a heat pipe

“…The relations (3) and (6) in the limit β → 1 transform to expressions for CVC obtained in [3] for the case of uniform distribution of alkali vapors in the volume of photoelectric converter. Analysis reveals that the output power W = εI in the case of optimal load current assumes the maximal value W max [3,4].…”

“…Analysis reveals that the output power W = εI in the case of optimal load current assumes the maximal value W max [3,4].…”

“…A model of photovoltaic effect under conditions of uniform distribution of alkali vapors over the converter volume (which corresponded to the experimental conditions of [1]) was developed in [3,4]. It was demonstrated that the photoelectromotive force arises in the case of nonuniform ionization of vapors within the gas cell.…”

“…A one-dimensional problem is considered, which enables one to trace qualitative changes compared to the model of ion diffusion constant [3].…”

Model of the Plasma Photovoltaic Conversion of Concentrated Solar Radiation: Short-Circuit Current and Open-Circuit Voltage

“…The maximum value of the measured photo-induced voltage was 4 V. A theoretical model of the PV effect in the photoplasma has been subsequently considered. An isothermal diffusive plasma model was developed to describe the electromotive force (EMF) formed between two cold electrodes immersed into low pressure plasma PL \ 1 Pa m, where P and L are the pressure and the typical scale of the plasma, respectively [6]. It was proven that the high value of the photo-induced voltage resulted from the high electron temperatures that were detected in the photoplasma using a probe technique [7].…”
