新华社纽约1月18日（路透社） - 杜邦周一表示，将额外投资1.75亿美元扩大太阳能电池材料生产线。
该公司将扩大其Tedlar产品，即用于太阳能电池背板。
这项额外的1.2亿投资是杜邦去年8月为太阳能项目预留的。
新的资金将用于该公司位于瑟克尔维尔，俄亥俄的工厂，Tedlar将于2011年9月开始生产。
NEW YORK, Jan 18 (Reuters) - DuPont (DD.N) said Monday it would invest an additional $175 million to expand a line of solar materials, boosting the chemical maker's commitment to alternative energy.
The company will expand its line of Tedlar products, which are used as a backing in solar cells.
The investment is in addition to $120 million DuPont set aside last August for solar projects.
The new funds will be used at the company's Circleville, Ohio, plant, which will start producing Tedlar in September 2011.
