EFFECT OF MULTI WINDOW LAYER ON THE PERFORMANCEOF A SOLAR CELL USING AMPS-1D

[摘要] In our days solar cells to thin films are increasingly used primarily because of their lowcost. In recent decades the performance of these cells were significantly improved. In thepresent work, we simulated solar cells p(Ga1−XAlXAs)/p(GaAs)/n(GaAs)) having amulti-layer window using software of the microelectronics and photonic (AMPS-1D) toanalyze certain parameters. In particular the properties of the window layer (thickness,doping ...) play a major role in the performance of the cell, and to optimize them, westudied their influence on photovoltaic cell. In order to demonstrate the importance of thetestimony of a window of the type layer p(Ga1−XAlXAs) ) of GaAs solar cells, acomparison of three cells, one with a layer window, the other layers with two windows andhe third with three windows layers was made. This comparison led to the conclusion thatthe proliferation of cascading windows layers results in an equivalent cell window. Forthis optimized cell structure the maximum Jsc =30.17mA/cm2, Voc=1.14V factor=90%are obtained under AM1.5G illumination, exhibiting a maximum onversion efficiency of32.06%.% (1 sun).
