“…This is because the low affinity reduces the top n-contact metal Schottky barrier height and less amount of bias potential needs to be sacrificed to overcome this Schottky barrier height across the top junction. It is noted the effect of TCO affinity on n-type emitter is just opposite to the effect of TCO affinity on the thin p-type emitter 12,26,27 where high TCO affinity can lead to better cell performance. On the whole, the modeling results demonstrated in this work indicate some clues to achieve high efficiency for the CZT (CdSe)/CIGS tandem cells.…”

Based on Crosslight APSYS, single junction ZnTe/CdSe, CdZnTe/CdSe and CIGS/CdS solar cells as well as CdZnTe(CdSe)/CIGS tandem cells are modeled. Basic physical quantities like band diagrams, optical absorption and generation are obtained. Quantum efficiency and I-V curves are presented. The results are discussed with respect to the interface recombination velocity and the related material defect trap states for ZnTe/CdSe single junction solar cells and the top TCO layer affinity for tandem cells. The projected efficiency obtained is 28% for one of the modeled twoterminal tandem cells. The modeling results give possible clues for developing CdZnTe(CdSe)/CIGS tandem solar cells with increased efficiency.

“…Whereas one-dimensional (1D) calculation with simplified theoretical model can be a relatively easy work, modeling of MJ including DJ and TJ solar cells has only been done by a few of research groups 13 and commercial software providers 14 . The Crosslight APSYS package 14 has been previously shown to be very effective in modeling TJ solar cells [8][9][10]15,17 with tunnel junction and DJ solar cells 10,16 including DJ cells using Si bottom junction 10 . In this work, based on Crosslight APSYS 14 , CZT/Si DJ and CZT/CT/Si TJ solar cells with tunnel junctions are modeled.…”

Based on Crosslight APSYS, we have made 2D simulation of dual and triple junction solar cells based on CdZnTe and CdTe material system on Si substrate with tunnel junctions. The basic physical quantities like band diagram, optical absorption and generation for these solar cells, and external quantum efficiency for individual subcell junctions are obtained. Current matching analyses and multi-sun concentration simulation are also performed. The modeling shows efficiency 28.85% (one sun AM1.5G) and maximum 32.65% (multi-sun concentration around 400 suns) for CdZnTe/Si dual junction solar cells and efficiency 34.92% (one sun AM1.5G) and maximum 40.10% (multi-sun concentration around 500 suns) for CdZnTe/CdTe/Si triple junction solar cells. The presented results indicate that the dual and triple junction solar cells with II-VI CdZnTe and CdTe on Si can achieve efficiency comparable to those III-V based compound on Ge substrate.

“…Numerical simulations were used by Zeman et al [7] to analyse and optimise the optical and electrical properties of tandem micromorph and triple-junction silicon-based solar cells. Xiao et al [8] modelled a thin film triple junction solar cell using the APSYS simulator, which is a general-purpose 2D/3D finite element analysis and modelling software for semiconductor devices.…”
