Journal ArticleDOI
Identification and analysis of partial shading breakdown sites in CuInxGa(1-x)Se2 modules
Elizabeth Palmiotti,Steve Johnston,Andreas Gerber,Harvey Guthrey,Angus Rockett,Lorelle M. Mansfield,Timothy J. Silverman,Mowafak Al-Jassim +7 more
TL;DR: In this paper, the authors used dark lock-in thermography (DLIT) to spatially observe localized heating when reverse-bias breakdown occurs on various CIGS mini-modules.
Journal ArticleDOI
Impact of Post-Deposition Recrystallization by Alkali Fluorides on Cu(In,Ga)Se2Thin-Film Materials and Solar Cells
Grace Rajan,Benjamin Belfore,Shankar Karki,Deewakar Poudel,Hamza Kahoui,Nicole Lanham,Elizabeth Palmiotti,Sina Soltanmohammad,Angus Rockett,Sylvain Marsillac +9 more
TL;DR: Using thermal evaporation, Cu(In,Ga)Se2 (CIGS) layers were deposited at low temperature (350°C) and high rate (10μm/h) using a single stage process.
Journal ArticleDOI
Recrystallization of Cu(In,Ga)Se2 Semiconductor Thin Films via InCl3 Treatment
Benjamin Belfore,Deewakar Poudel,Shankar Karki,Sina Soltanmohammad,Elizabeth Palmiotti,Thomas Lepetit,Angus Rockett,Sylvain Marsillac +7 more
TL;DR: In this article, the authors demonstrate that InCl3 can be used effectively to recrystallize CIGS for temperature as low as 450 °C, but that it also induces a modification of the surface composition.
Journal ArticleDOI
In Situ Recrystallization of Co-Evaporated Cu(In,Ga)Se2 Thin Films by Copper Chloride Vapor Treatment towards Solar Cell Applications
Deewakar Poudel,Benjamin Belfore,Tasnuva Ashrafee,Elizabeth Palmiotti,Shankar Karki,Grace Rajan,Thomas Lepetit,Angus Rockett,Sylvain Marsillac +8 more
TL;DR: In this paper, a modified three-stage process was used to produce CIGS thin films and devices using high deposition rates and a low temperature during the process, a copper chloride vapor treatment was introduced in between the second and third stages to enhance the films properties.
Proceedings ArticleDOI
Ex-Situ Recrystallization of CIGS via Metal Halides
Benjamin Belfore,Deewakar Poudel,Elizabeth Palmiotti,Grace Rajan,Shankar Karki,Angus Rockett,Sylvain Marsillac +6 more
TL;DR: In this paper, a modified 3-stage process with low stage 1 and stage 2 deposition temperatures was used to create CIGS absorber layers with high current collection capabilities. But, the authors pointed out that high temperature is often necessary for high efficiency.
