“…FTIR results 16 are in good agreement with Raman data, presenting characteristic vibration of aluminum oxide. In Figure 3c, the most intense peak is shown about 507cm -1 , and although it may be related to alumina, most probably it can be associated to crystalline silicon 27,28 . In this case, the Si would be originated from the substrate 24,25 , diffusing to the interface substrate/Al, as discussed before, in good agreement with some peaks found out the XRD diffractograms.…”

Alternative materials for use in electronic devices have grown interest in the past recent years. In this paper, the heterojunction SnO 2 /Al 2 O 3 is tested concerning its use as a transparent insulating layer for use in FETs. The alumina layer is obtained by thermal annealing of metallic Al layer, deposited by resistive evaporation technique. Combination of undoped SnO 2 , deposited by sol-gel-dip-coating technique, and Al thermally annealed in O 2 -rich atmosphere, leads to fair insulation when the number of aluminum oxide layers is 4, with 0.3% of the current lost through the gate terminal as leakage current. This insulation is not obtained for devices with alumina layer treated for long time, under room atmosphere, due to degradation of the insulating film and interfusion with the conduction channel even using Sb-doped SnO 2 . The annealing of Al deposited on soda-lime glass substrate leads also to the formation of a Si layer, crystallized at Substrate/Al 2 O 3 interface. The conclusion is that for an efficient insulation the thermal annealing must be short and then, O 2 -rich atmospheres are preferred.

In this study, aluminum induced texturing (AIT) technique is used to increase light absorption in thin film by way of increasing the portion of the diffuse transmitted light (haze). For this purpose, various AIT process parameters such as starting aluminum thicknesses, annealing temperature and time, etching time, etchant's concentrations, and temperature of etching are known to affect the final texture. We have investigated the effect of aluminum thickness and etching time on AIT process while keeping the other parameters fixed. Our results show that by changing initial aluminum thickness and etching time, it is possible to control surface morphology of glass substrate and the resulting optical diffuse transmittance. In addition, diffuse transmittance is increased over the visible range of solar spectra and total absorption by a‐Si:H is increased. (© 2015 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)

“…1 Introduction Light management in thin film solar cells is important in order to increase the optical path of light in highly defective absorber layers [1][2][3][4][5][6][7][8][9]. In this manner, it can be particularly used in further reducing the absorber thicknesses in rare material (i.e., Cd, Te, Ga, etc.)…”

Aluminum induced texturing (AIT) is one of the most promising texturing methods, which can be applied on glass substrates for solar cell applications. Combination of different dimensional structures exhibits the opportunity to achieve enhanced light trapping schemes. Here in this study, float glass and macro textured sandy and prism glasses went through Aluminum induced texturing (AIT) process in order to enhance light management. Surface morphologies were investigated by FE‐SEM and optical measurements in terms of transmittance and haze were conducted. Micro or nano sized craters were formed on each type of glass surface successfully by using acidic and basic etching solutions. It was shown for every type of glass that AIT process enhances haze values remarkably. Moreover, it was demonstrated that basic solution is superior to acidic solution in terms of optical properties. In this work, random macro‐scale surface texture and imprinted inverted pyramid‐like pattern were used to combine AIT textures to attain high haze values. Superior haze was achieved from macro‐nano combined texture surface having more scattered light from prism glass substrate with a maximum haze value of 90 %. Comparison of AIT textured float, prism and sandy glasses in terms of haze.
