Figures

Image of FIG. 1.
FIG. 1.

(a)–(c) SEM images of 3 different periodic honeycomb textures and (d)–(f) the surfaces of the 1-μm-thick μc-Si:H solar cells deposited on them. The periods of the substrates are (a) and (d) 1 μm, (b) and (e) 1.5 μm, and (c) and (f) 2 μm.

Image of FIG. 2.
FIG. 2.

J-V parameters of 1-μm-thick μc-Si:H solar cells fabricated on honeycomb textures with periods of P = 1.4 μm or 1.5 μm as functions of the aspect ratio, H/P. The star symbols represent the results obtained with a wide-gap (p)nc-SiOX layer instead of the standard (p)μc-Si:H layer.

Image of FIG. 3.
FIG. 3.

Relationship between the period of textured substrates and the J SC in n-i-p μc-Si:H cells with a thickness of 1 μm. Open circles represent data obtained with patterned Al substrates obtained by anodic oxidation of Al (see Ref. 14).

Image of FIG. 4.
FIG. 4.

External quantum efficiency spectra of the μc-Si:H solar cells deposited on a flat substrate and a honeycomb texture with P = 1.5 μm and an optimum H/P.

Image of FIG. 5.
FIG. 5.

Absorption spectra of the μc-Si:H cells fabricated on a flat and the honeycomb substrate with P = 1.5 μm. For the honeycomb substrate, the corresponding EQE spectrum is also plotted. Black arrows indicate the absorption peaks due to the Fabric-Perrot interference. The x axis is linearly proportional to the inverse of wavelength for better visibility.

J-V parameters of μc-Si:H cells fabricated on a flat and honeycomb textures with a period of 1.5 μm and aspect ratio of ∼0.23. All the cells have an active area of 1 cm2.
