ZnSnP 2 thin-film solar cell prepared by phosphidation method under optimized Zn/Sn atomic ratio of its absorbing layer

Structure, composition and photoconductivity analysis of zinc tin phosphide ternary compound nanoparticles synthesized by chemical method

“…Moreover, ZTP is non-toxic, highly stable and the constituent elements are abundant [1]. Recently, several studies have been reported using ZTP as an absorbing layer in solar cells [8][9][10], and as sensing layer in photo-detectors of ultra-violet and near infrared wavelengths [11,12].…”

“…Several methods have been explored for the preparation of ZTP in form of crystals and thin films using elemental Zn, Sn and P or in combination of Zn-P and Sn-P compounds as starting materials. They include melt solution growth [4,[13][14][15], flux method [9,10], thermal or electron-beam evaporation [2,11,12,16,17], molecular beam epitaxy [5], liquid phase epitaxy [18], phosphidation of Zn-Sn layers [8,19] and others [20], generally, involving high temperature ([ 600°C) and/or vacuum. In some of these methods, the processes are very tricky due to the complexity in thermodynamic phase formation and a large difference in the vapor pressure between Zn and Sn [21,22].…”

“…The nano-morphologies, in principle, can exhibit high absorption cross section and excitonic effects, and therefore allow enhancement of light sensing property of the materials [23]. Moreover, control of structural order and defects which typically depends on Zn/Sn ratio in ZTP [8], and doping are more feasible. Synthesis of ZTP nanowires has been reported by a chemical vapor deposition process using Zn and SnP 3 as precursors [24], and a solution-liquid-solid reaction of Zn and Sn melts in the presence trioctylphosphine (TOP) at * 365°C [25].…”

Fundamental Materialistic Properties of ZnSnP2 for Solar Energy Conversion and Environmental Friendly Photovoltaic Devices

“…In spite of all these work, it has been seen that the theoretical results obtained for elastic constants which experimentally need single crystals of these compounds differ considerably with the available experimental data [4][5][6][7][8]. A considerable amount of experimental and theoretical work related to the prediction of crystal structures, lattice constants, phase diagrams and related properties of these compounds has been done during the last few years [9][10][11][12][13].…”

Structure and Properties of ZnSnP2 With the Application in Photovoltaic Devices by Using CdS and ZnTe Buffer Layers

“…ZnSnP 2 semiconductors open up the possibility of fabricating a graded multijunction solar cell using the ordered chalcopyrite as the top layer, with progressively more disordered layers underneath, free from lattice matching problems [7][8][9][10]. A considerable amount of experimental and theoretical work related to the prediction of crystal structures, lattice constants, phase diagrams and related properties of these compounds has been done during the last few years [9][10][11][12][13]. In spite of all these works, it has been seen that the theoretical results obtained for elastic constants which experimentally need single crystals of these compounds differ considerably with the available experimental data [4][5][6][7][8].…”
