(a) Schematic of the InGaN/GaN solar cell structure. AFM scans of the surface of the (b) smoother sample with rms roughness of and (c) rough sample with rms roughness of .
Measured absorption (solid), average (solid with error bars), maximum and minimum (dashed curves) EQE curves for (a) smoother and (b) rough samples. The average EQE and its standard deviation (error bars) were determined from measurements of a total of 12 devices located in the same area of the sample where the absorption was measured.
IQE for the smoother (dashed) and rough (solid) surface solar cells, determined from the ratio between the EQE and the light absorption curves.
Current density vs voltage for solar cells, with rough (solid) and smooth (dashed) surfaces, under 1 sun-AM1.5G conditions.
