Light Scattering and Current Enhancement for Microcrystalline Silicon Thin-Film Solar Cells on Aluminium-Induced Texture Glass Superstrates with Double Texture

Table 1

Measured haze values of visible light and calculated surface morphology parameters for the different superstrates used. With the exception of haze, all parameters were measured after TCO deposition and TCO texturing; that is, the AIT glass superstrates are double-textured (microtextured glass covered with nanotextured TCO).

	Reference	AIT-1	AIT-2
Haze (no TCO) (%)	0	50	70
Haze (with TCO) (%)	12	65	74
RMS (nm)	36	188	284
Autocorrelation length (nm)	150	742	1050
Average surface angle (°)	20	40 (max at 30 and 50)	40 (max at 30 and 50)
