Silicon vs. CIGS: With solar energy, the issue is material | CNET

"Panels that harvest energy with CIGS (copper indium gallium selenide) cost far less to make and install, say backers. The material can be sprayed onto foil, plastic or glass or incorporated into cement and other building materials. Conceivably, the entire exterior of a house or building could become a solar generator."

Unfortunately, all of these technologies must fight the politics of oil.
