Electric power glitches and PV manufacturing: using SEMI standards to increase yield and reduce cost


By Alex McEachern, President, Power Standards Lab

PV manufacturers can quickly reduce their costs, and increase their yields, by using SEMI standards that were originally designed to help semiconductor fabs deal with power glitches and power costs. SEMI, the global industry association serving the manufacturing supply chains for the microelectronic, display and photovoltaic industries, has two well-established electric power standards that could prove especially useful for PV manufacturing: SEMI F47, which helps equipment deal with power disturbances, and SEMI E3, which helps users understand how much electric power is used in their recipes. This paper provides a method of lowering costs and increasing yield by applying these standards in the PV manufacturing industry.
