Experimental study and theoretical analysis of photoelectric characteristics of AlxGa₁₋xAs–p-GaAs–n-GaAs-based photoconverters with relief interfaces

We studied experimentally the photoelectric characteristics of the AlxGa₁₋xAs–p-GaAs–n-GaAs structures with relief interfaces. A theoretical analysis of spectral dependences of internal quantum efficiency of short-circuit current in the above solar cells (SC) was performed. In particular, the low-en...
