I think that the game is not over for anyone. It’s all about continuous research of technologies, which are cometeing between each and one of them…. I like the nanosolar’s one .. http://www.best-solar-energy.com/solar-cells/nanosolar-ships-first-panels/

The problem with most thin-film solar technologies is that they are often manufactured with expensive and sometimes harmful substances such as gallium and indium. How do these models measure up?

I am more a fan of CPV (Concentrator Photovoltaic) systems, as they are cheaper and more efficient. SolFocus has a model that achieves 40% efficiency:
