1. Improvement the Efficiency of CIGS Thin Film Solar Cells by Changing the Doping of the Absorbent Layer and Adding the InAsP Layer

H. Firoozi; M. Imanieh

Volume 6, Issue 1 , Winter and Spring 2018, , Pages 7-14

Abstract
  In this article, the functionality of solar cells structure based on CuIn1-xGaxSe2 is investigated. This type of solar cell consists of different layers, namely ZnO (TCO layer), Cd_S (Buffer layer), CIGS (Absorbent layer), and MO (Substrate layer). Two layers, Cd_S and CIGS, form a PN Junction.  ...  Read More

2. A Numerical Optimization of an Efficient Double Junction InGaN/CIGS Solar Cell

M. Feli; F. Parandin

Volume 6, Issue 1 , Winter and Spring 2018, , Pages 53-58

Abstract
  An efficient double junction InGaN/CIGS solar cell can be simulated using Silvaco ATLAS software. In this study, a thin CdS top cover layer is used as the anti-reflector layer. To reach the current matching condition, changing the thickness of this CdS layer, we can enhance the short-circuit currents ...  Read More

3. Design and Simulation of a Highly Efficient InGaN/Si Double-Junction Solar Cell

S.M. Ahmadi; F. Parandin

Volume 5, Issue 2 , Summer and Autumn 2017, , Pages 157-162

Abstract
  A solar cell is an electronic device which not only harvests photovoltaic effect but also transforms light energy into electricity. In photovoltaic phenomenon, a P-N junction is created to form an empty region.  The presented paper aims at proposing a new highly efficient InGaN/Si double-junction ...  Read More
