Popis: The investigation is aimed at elaboration of technology for submicron p + - GaAs layer formation on micro/nanotextured n -GaAs substrates by using low-temperature (550 °C) diffusion of zinc to take the advantage of optical and recombination properties of textured interface for solar cells. Process duration, surface microrelief morphology (dendrite or quasi-grating (grating-like)) and the substrate doping impurity concentration were varied. Optical, photoelectric and electrical properties of p + – n junction were studied to optimize the process conditions. The highest efficiency was obtained in structures with a quasi-grating surface microrelief, substrate doping close to N d ≃ 10 17 cm − 3 and process duration about 45 min.
