Solar/Photovoltaic

Providing specialized materials and solutions for the conversion of sunlight to electric power is second nature to Williams Advanced Materials (WAM). Our focus on solar market technologies began more than 20 years ago with the research and development (R&D) of high-purity, unique materials for photovoltaic (PV) applications.

Today, WAM is a single source provider of specialized and integrated solar technologies, solutions and materials to PV segments, including thin film, concentrator photovoltaic (CPV) and crystalline silicone. In the thin film PV arena, broad global manufacturing capabilities allow WAM to offer custom solar thin film layer and wafer materials in addition to compound semiconductor based (II-VI and III-V) technologies. In the CPV segment of microelectronic packaging, our sub mount physical vapor deposition (PVD), CDV Shield Kit Precision Parts Cleaning and Valuable Material Management Services are sought worldwide.

WAM is dedicated to working with each solar PV customer to package a complete solution. Our established materials development capabilities, thin film coating services, chamber cleaning, and materials management competencies make us an ideal choice in highly specialized and custom PV development. We are strategically positioned to achieve results from R&D stages through the support of large manufactured volumes. These demonstrated efficiencies, combined with our respect for and understanding of the continual evolution of solar material requirements and individual customer needs, ultimately translate into a one stop convenience and low total cost of ownership for our customers.
