Techniques de détermination des paramètres de recombinaison et le domaine de leur validité d’une photopile bifaciale au silicium polycristallin sous éclairement multi spectral constant en régime statique

“…Pour i supérieur à trois, cette série est négligeable telle que cela a été défini à partir de la modélisation du spectre d'absorption lumineuse [15].…”

“…Ces recombinaisons sont caractérisées par des paramètres électriques (résistances série et shunt, et inductance équivalente de la cellule) [11,14,15] et électroniques (longueur de diffusion, durée de vie des porteurs minoritaires, vitesses de recombinaison à la jonction et à la face arrière).…”

Applications

“…The demand for a reliable, long-lasting power source was the major reason for application of solar cell. The first practical application of solar cells was developed for space applications, starting with US satellite "Vanguard" in 1958, which was equipped with a dual power system of chemical batteries and silicon solar cells, of which the batteries failed after a week while the silicon solar cells kept the satellite communicating with Earth for years [9,10]. Since then, PV solar generators have been remained as the best choice for providing electrical power to satellites in an orbit around the Earth.…”

Characterization of Cu(In,Ga)Se2thin films and solar cells by photoacoustic spectroscopy

“…Cu(In,Ga)Se 2 (CIGS) thin film solar cells used CIGS as the absorber layer draw our attention as next-generation solar cells, because they have properties such as high absorption coefficient, 1) long-term stability, 2) and radiation hardness. 3) A recorded efficiency of CIGS solar cells of up to 20.8% has been achieved.…”

“…The conversion efficiency of 25 to 28% is expected by the CIGS solar cells with band gap energy of 1.4 eV which is ideal for solar cells. 1) In order to increase the conversion efficiency of the CIGS solar cell, it is necessary to develop the characterization of CIGS thin film further.…”
