T. Minemoto et al., Theoretical analysis of the effect of conduction band offset of window/CISlayers on performance of CIS solar cells using device simulation, SOL EN MAT, 67(1-4), 2001, pp. 83-88
One of the most important factors of CdS leading to high performance in Cu(
In,Ga)Se-2 (CIGS) solar cells is appropriation of the conduction band offse
t of CdS/CIGS layers. However, it is not clearly explained. In this study,
device modeling and simulation were conducted to explain the effect of cond
uction band offset of window/CIGS layers on performance of CIGS solar cells
. As a result of calculation, excellent performance can be obtained when th
e conduction band of window layer positions higher by 0-0.4eV than that of
CIGS. (C) 2001 Elsevier Science B.V. All rights reserved.
