“…[23][24][25][26][27][28][29][30][31][32][33][34][35][36] Our R sh found to be higher than that of the previous contributions on FTO films. 14,23,24,26 But, the decreasing trend of sheet resistance with increasing film's thickness is consistent with that of earlier measurements. 14,36 The thickness dependence of R sh has been understood to arise from any one or all of the following factors: the Fluorine incorporation at regular oxygen sites, increased oxygen vacancies and incorporation of Sn at the interstitial site 14 ).…”

The dependence of the structural, optical and electrical properties of the FTO thin films on the film thickness (276 nm - 546 nm), calcination environment, and low temperature plasma treatment were examined. The FTO thin films, prepared by spray pyrolysis, were calcinated under air followed by either further heat treatment under N2 gas or treatment in low temperature atmospheric plasma. The samples before and after calcination under N2, and plasma treatment will be represented by Sair, SN2 and SPl, respectively, hereafter. The thin films were characterized by measuring the XRD spectra, SEM images, optical transmittance and reflectance, and sheet resistance of the films before and after calcination in N2 environment or plasma treatment. The presence of sharp and narrow multiple peaks in XRD spectra hint us that the films were highly crystalline (polycrystalline). The samples Sair with the thickness of 471 nm showed as high as 92 % transmittance in the visible range. Moreover, from the tauc plot, the optical bandgap Eg values of the Sair found to be noticeably lower than that of the samples SN2. Very surprisingly, the electrical sheet resistance (Rsh) found to decrease following the trend as Rshair > RshN2 > RshPl. The samples exposed to plasma found to possess the lowest RshPl (for film with thickness 546 nm, the RshPl was 17 Ω/sq.).

“…These include Zinc Sulfide [14] and certain oxide semiconductors such as Zinc Oxide [15], Tin Oxide [14], Titanium Oxide [16], Boron Oxide [14], Indium Oxide [14], and Tin doped Indium Oxide frequently known as Indium Tin Oxide (ITO) [17,18]. Among these selective heat reflector materials, ITO is reported to be the most suitable material for the fabrication of heat reflectors [17,18].…”

“…Due to its high optical transmittance in the visible and nearinfrared light [18][19][20][21][22] as well as high reflectance [18] in the infrared spectral region, ITO is frequently used in photovoltaic devices [18][19][20][21][22][23] and various optoelectronic devices [19], infrared reflectors [18,23], and flat panel display [18,23]. Indium Tin Oxide has also been used as transparent electrodes for spectroelectrochemical studies due to its low electrical resistivity and its wide electrochemical window [24].…”

“…In the literature, there are various deposition techniques that have been used to grow ITO films which includes chemical vapour deposition [19], reactive plating [26], electron beam evaporation [19,20], pulsed laser deposition [27], spray pyrolysis [18,19], sol-gel [19,28], thermal deposition [22], DC magnetron sputtering [19,21,24], and radio frequency (rf) magnetron sputtering [19,[30][31][32]. However, each of the ITO films deposition techniques has its own advantages and disadvantages.…”

One problem with concentrating photovoltaic systems is the increase in operating photovoltaic module temperature which results in power output reduction. Indium Tin Oxide (ITO) coated glasses exhibit both high transmittance in the visible region and high reflectance in the infrared region of the solar spectrum. Such materials can be used as selective windows in photovoltaic modules operating under concentrating system enabling passive cooling. In this paper, a Heat Reflector Window (HRW) consisting of a glass coated with 180 nm layer of ITO was experimentally tested. The ITO coated glass had a transmittance of about 85% in the visible region and over 80% reflectance in the infrared region of the solar spectrum and was placed at the exit aperture of a Compound Parabolic Concentrator (CPC). Results indicate that the temperature of a photovoltaic module under CPC with the HRW was reduced by about 50% as compared to a similar photovoltaic module with CPC but without the HRW. However, due to presence of the HRW at the exit aperture of the CPC, the photovoltaic module with the CPC and HRW received less solar irradiance compared to a similar photovoltaic module with the CPC but without HRW.

“…Spray CVD (mist CVD or spray pyrolysis) of ITO films is instrumentally cheap and needs substrate heating so that it should be focused to the deposition onto glass or silicon substrates. Table I show reports [1][2][3][4][5][6][7][8][9][10][11][12][13] on spray CVD of ITO films using indium chloride and tin chlorides which are stable and relatively cheap raw materials. Tin (IV) chloride SnCl 4 was used as the tin-doping source.…”
