nAlGaAsGaAsnThe method of formation of nGaAs\рAlGaAs\р+GaAs heterostructure by the MOC vapour deposition method in the temperature range of 630-700 °С is presented. The investigation of the charge carrier concentration dependence on the thickness of the n-GaAs epitaxial layers doped with silicon and AlAs concentration dependence on the thickness of the AlxGa1-xAs solid solution layer was carried out. The high structural perfection of the obtained epitaxial layers of the graded-gap structure is shown. A solar cell with an 1 см2 active area is created. It is shown that the value of the efficiency coefficient ( = 25,37 %) of the obtained solar elements is higher than this one for solar elements based on GaAs. |
