Commercial silicon solar cells have textures on their front and rear surfaces to minimize front-surface reflection and maximize the path length of weakly absorbed light.
The photocell with housing serves the examination of the outer photoelectric effect. The properties of the outer photoelectric effect show in the dependence of the current over voltage characteristic line of a photocell in dependence on intensity and wavelength of the light entering the photocell.
In a 180- μ m-thick silicon absorber, considering light in the 1000–1200 nm wavelength range, this difference in first-pass path length would lead to 0.13 mA/cm 2 additional photocurrent generated during the first pass with ideal-random pyramids.
By contrast, simulations from the ideal-random pyramids map lead to a reflectance peak at ±39.5°, as expected from our analysis of ideal-inverted pyramids. This emphasizes how inaccurate it can be to assume a 54.7° pyramid base angle when simulating the optics of silicon solar cells.
Because the slit function changes with the relative size of the aperture-slit combinations, mis-matches (even to smaller widths) can lead to increased bandwidths. This means that the above formula for slit-slit combinations will not apply to aperture-slit sizes.
Similarly, when using fiber optics (even slit-shaped fibers) the slit width or aperture only applies when smaller than the fiber. If the fiber is smaller then the slit (or aperture) it is the fiber that determines the expected behavior of the system.
