Certification and Characterization of Photovoltaic Packaging
Photovoltaic (PV) installations are divided into three subassemblies capable of energy generation: the cell, the module, and the array. PV companies are diversified based on the type of cell they manufacture, and each manufacturer usually specializes in one cell chemistry. Polymeric packaging allows PV manufacturers to lower their offering price, making them more competitive with other energy sources. In addition to cost, customers are sensitive to product certifications. Manufacturers interested in selling on the global market must provide both environmental and safety certifications. The chapter also discusses characterization of polymeric heat conduction. When applied to polymers, heat increases polymer chain motion and causes the polymers to undergo morphological changes manifesting in dimensional, mechanical, and electrical property shifts. Engineers must compensate for these changes in their design by estimating the magnitude of the property shift from material characterization techniques.
