چکیده
The gradual substitution of sulfur atoms (S) by selenium (Se) in Cu2ZnSn(S1-y Sey )4 compounds causes a linear increase the optical band-gap. For this reason, those are suitable to implement band-gap engineering compositionally graded solar cells. In paper, we have worked take advantage feature enhance performances basic uniform Kesterite and Stannite CZTS1–ySey influence Tow grading profile was investigated: fully (a) double (b). Fully Cell showed better parameters than Double cells it appeared that front had disruptive effect on cell parameters. contrary back ameliorates significantly all As result, efficiency kesterite stannite enhanced from 9.05 5.22% 16.65 15.77 % respectively.

In this paper, a thin-film InP-based solar cell designed and simulated. The proposed InP solar cell has a periodic array of plasmonic back-reflector, which consists of a silver layer and two silver nanowires. The indium tin oxide (ITO) layer also utilized as an anti-reflection coating (ARC) layer on top. The design creates a light-trapping structure by using a plasmonic back-reflector and an an...
متن کاملImproving solar cell efficiency using photonic band-gap materials
The potential of using photonic crystal structures for realizing highly efficient and reliable solar-cell devices is presented. We show that due their ability to modify the spectral and angular characteristics of thermal radiation, photonic crystals emerge as one of the leading candidates for frequencyand angular-selective radiating elements in thermophotovoltaic devices. We show that employing...
