Though controversy still exists regarding the comparison between thin-film and polysilicon technologies, we trade insiders have no disagreement in regarding thin-film as the future of PV, in addition to being a trend already," claimed Li Hejun, Hanergy’s chairman, speaking last month at the launch of his book New Energy Revolution – the Power to change China and the World.Mr. Hejun is apparently serious about this assertion as his company plans to scale up CIGS production by 5.25GW. Strangely the company also plans to expand a-Si production??? While I don't disagree that thin-film is the future of photoelectrics I'd argue that the timing of when that future is going to come around is completely up in the air. It's sorta like LEDs or solid state hard drives - they're the future but things take a mysterious amount of time to develop.
