San Francisco—Encore Solar says it can lower the cost of cadmium telluride solar modules by 20 percent or more as well as help the technology break through a looming efficiency wall. But getting funding in Silicon Valley could be a bit challenging because of the past history of the people behind the company. Encore wants to produce CdTe modules with electroplating. Currently, CdTe companies like First Solar through vapor deposition: CdTe vapor is introduced into a vacuum chamber and forms films that become a solar cell. While proven and reliable, deposition requires expensive equipment and the materials have to be heated to 500 to 600 Celsius. In electroplating, substrates are dipped into a water-based solution containing cadmium and telluride ions. A voltage is applied and, voila, photovoltaic films are formed. The active solar layers don’t form as fast, but the process t...
