(Reuters) - Big Asian manufacturers are scooping up next-generation U.S. solar technology on the cheap, but face a long slog to turn these start-ups into serious competitors for the Chinese panel makers that now dominate the market.
Earlier this month, China's Hanergy Holding Group Ltd became the latest Asian manufacturer to make a bet on a U.S. maker of solar panels that use copper indium gallium selenide technology, or CIGS, when it agreed to buy Silicon Valley startup Miasole.
