A diversity of new processes

New deposition methods for CIGS solar cells: This article by Peng Shou (CNBM), Jimin Ma (CEO of Sol Array), and Paul Beatty (CTO at Sol Array) reviews and compares the technical and commercial merits of recent lower cost deposition methods for solar cells using quarternary compound semiconductors such as copper indium gallium diselenide (CIGS), including new types of sputtering and printing.

In the past, deposition of copper indium gallium (di)selenide (CIGS) for low cost, large area solar panels was achieved either by evaporation of these four elements, or by sputtering the three metal precursors and selenizing with hydrogen selenide gas, slowly working downwards through the film over several hours. But these techniques can be expensive to …
