Impact of different thermal treatments on ZnS physical properties and their performance in CdTe solar cells

Obtention of solar cell parameters, through convergence of iterative cycles. Part 1: Theoretical analysis and cycles proposal

“…These simulations were done on the [0 V, 1 V] range, using the same C program reported in [2] . Laboratory fabricated solar cells usually function in this voltage range [14] , [34] , [35] , [36] , [37] , [38] , [39] , [40] , [41] , [42] , [43] , [44] , [45] , [46] , [47] , [48] , [49] , [50] , [51] , [52] , [53] , [54] . Briefly, the C program solved equation 1 in [2] within an accuracy of 10 −15 A for each voltage.…”

“…For simplicity purposes and to facilitate comparison with the deduced solar parameters, all simulation parameters (except n ) were chosen as power of 10, i.e., the simulation parameters were , , mA and μA. Both and are three orders of magnitude larger than and , respectively, which is usually the case found in second generation solar cells [14] , [34] , [35] , [36] , [37] , [38] , [39] , [40] , [41] , [42] , [43] , [44] , [45] , [46] , [47] , [48] , [49] , [50] , [51] , [52] , [53] , [54] . The value of n was chosen , which is a value in the range of 2 to 3, which is also the usual case found in second generation solar cells [14] , [34] , [35] , [36] , [37] , [38] , [39] , [40] , [41] , [42] ,…”

“…The ZnS having band gap energy of 3.6 eV is considered as an efficient photocatalyst because it is nontoxic and chemically stable. [46] When ZnS is irradiated with UV light, it generates reactive oxygen species from water molecules which ultimately oxidize organic substrates effectively. [47] Qi and collaborators determined the concentration of SRB using microbially synthesized ZnS as photocatalyst for degradation of methylene blue (MB).…”

Effects of annealing on ZnS films produced by CBD method

“…The thin film of zinc sulfide (ZnS), which has direct bandgap energies range from 3.50-3.70 eV at room temperature, is used for the semiconductor layers of solar cells and other technological devices [4][5][6]. ZnS is used as a buffer layer in CIGS, ZCTSSe, and CdTe cells since it has ntype conductivity due to a sulfur deficiency defect [7]. This material with a high refractive index (2.25-2.35) is found in cubic (zinc blende) and hexagonal (wurtzite) crystal structures [8,9].…”
