“…Due to solar cell stability-related issues, qualitative SIMS analysis was mainly dedicated to Cu and/or Cl diffusion into the cell structure for cells back-contacted with Cu-containing material [5][6][7]. It was also used to determine residual Cl concentration in CdTe following a wet CdCl 2 treatment [8] and to investigate the CdS/SnO 2 interface in solar cells [9]. Furthermore, qualitative SIMS was used for studying the effect, on the efficiency of the solar cells, of the etching procedure [10,11] and different materials used as electrodes on the CdTe surface [12].…”

“…Even in the undoped CdS layer, Sn and Cl have atomic concentrations of 2 ϫ 10 17 and 4 ϫ 10 17 atoms/ cm 3 , respectively. The relatively high Sn concentration found in the undoped sample could be caused by the thermal diffusion of the Sn elements in the ITO substrate, 29 while the Cl contamination could be attributed to the Cl impurities also present in the ITO/glass substrate 29 and/or those in propylene glycol. On the other hand, the atomic concentrations of Sn and Cl in the DMTC-doped CdS film are 6 ϫ 10 17 and 4.5 ϫ 10 18 atoms/ cm 3 , respectively, and they are larger than those in the undoped CdS film.…”

A series of systematic investigations has been conducted to examine the doping effects of dimethyl-tin-dichloride (DMTC) on the structural, electrical, and optical properties of CdS films used for photovoltaic applications. After the DMTC doping, Sn and Cl concentrations in CdS are found to increase to 6×1017 and 4.5×1018atoms∕cm3, respectively; the CdS grain size also tends to increase. A slight increase in the electrical conductivity is discussed in conjunction with the increase in the grain size and the Cl donor concentration. In addition, the optical-absorption spectra reveal almost no change in the band gap of CdS due to the doping, while the spectra indicate a deterioration of the crystallinity of the heavily doped CdS. The influence of the DMTC doping into the CdS films on the formation of the CdS∕CdTe heterostructure is also discussed. With an increase in the grain size of the CdS underlayer due to the DMTC doping, the degree of the (111) preferential orientation of CdTe increases, which generally corresponds to an improvement in the photovoltaic performance. On the other hand, a fairly small reduction is observed in the sulfur fraction in the CdTe1−xSx mixed-crystal interlayer, which indicates no marked deterioration at the CdS∕CdTe interface. The DMTC doping is also effective in reducing the optical reflectance in almost the entire active spectral region of the CdS∕CdTe solar cell.

“…CdS is an n-type semiconductor which has direct band gap (E g = 2.42 eV) and optical absorption suitable for photovoltaic applications as window coatings in many types of solar cells with absorber materials such as Cu(In, Ga)Se 2 [7], CdTe [8,9] or CuInSe 2 [10,11]. Furthermore, CdS nanocrystals are applied for lasers [12], biological labels [13,14], photoconducting cells in sensors [15] and photoelectrocatalysis devices [16][17][18][19].…”
