JUNCTION RECOMBINATION VELOCITY DETERMINATION INITIATING THE SHORT-CIRCUIT AND LIMITING THE OPEN CIRCUIT OF A MONOFACIALE SOLAR CELLS CONTAINING THIN FILM Cu(In,Ga)Se2(CIGS) UNDER HORIZONTAL ILLUMINATION IN STATIC MODE

A theoretical study of thin layer CIGS solar cells (for the CIGS low in copper i.e. ? ? ? ? ? ? 0,9 Cu Ga In ? ? [1]) under monochromatic illumination in static regime at the front surface is presented.We propose a method of junction recombination velocity determination, initiating the short-circuit (Sfsc) and limiting the open circuit (Sfoc). The determination of Sfoc is obtained from the curve of photovoltage versus Sf, and the determination of Sfsc is through from the curve of the photocurrent density according to Sf
