The Warriors: 2011

Very Smart Students + Bolts + Nuts + Sockets = the chassis has taken shape !!

Stingray chassis arrives - Sample of solar cells available

The chassis ordered by Molly Gilbert, University of Arizona Tech Park, arrived at Pueblo HS on November 28
Many thanks

Global Solar gave us a sample of 5 cells connected in series
They will be used by Students to learn about solar cell properties
The cells are made with copper, indium, gallium, and selenium

Please study:

and research other pages in the web

Many thanks to Global Solar for their support

High Volume Manufacturing of Flexible and Lightweight CIGS Solar Cells at Global Solar Energy Corporation

To help me describe to our Students the manufacturing method for the hundreds of solar cells we will be using in the Competition, I will very briefly review Britt, Wiedeman, Schoop and Verebelyi, 2008 IEEE Photo Voltaic Conference:

Global Solar uses a batch manufacturing process based on stainless steel webs up to 1000 meters long and about 32 cm wide, 25 microns thick.

The back contact is made of Molybdenum. A thin Chromium coating is applied to enhance adhesion of the Molybdenum coating to the stainless steel web. Both metals are deposited by pulsed DC sputtering.

Copper, Indium, Gallium, and Selenium are deposited by multiple source co-evaporation in the equipment shown in Fig. 2 below. The thickness of the CIGS film is ~ 1.7 micron.

There is a buffer layer made of Cadmium Selenide, deposited from a solution, about 0.08 micron thick.

The top electrode is a transparent conducting oxide deposited by pulsed DC sputtering with the equipment shown in Fig. 3 below. The thickness of about 0.1 micron.
