Description China Sunergy hopes more than a billion people see the light of energy from the sun. The company, via operating subsidiary Sunergy Nanjing, makes photovoltaic (PV) cells used in the manufacture of solar energy panels. The company's plant in China produces up to 320 megawatts (MW) of solar cells per year. In addition to making the industry standard positively charged P-type PV cells, China Sunergy is also conducting research into production of new types of solar cells, including negatively charged N-type cells. The company also assembles solar cells into solar modules. While a small number of German firms buy China Sunergy's cells, the majority of its revenues comes from within China.
