Solar cells hitting the big time?

From the New York Times:

The world’s largest for-hire chip maker could soon start manufacturing solar cells and LED lights. The company’s entry into these nascent industries will catch the attention of existing makers, which could find themselves battling one of the most formidable manufacturers on the planet. Taiwan Semiconductor could drive down prices, as it did for computer chips. But the lower prices could also stimulate demand for what are now expensive technologies.
