Diamond DESERT Films provide significantly improved electrical performance. High volume resistivity and low leakage current improve electrical insulation and enable „PID Zero“ performance. As illustrated in the figures below, improved electrical performance results in increasing energy yield. Key Technical Attributes Performance Advantages • Significantly reduced degradation rates • „PID Zero“performance • 10-20x lower Water Vapor Transmission Rate (WVTR) • Outstanding Volume Resistivity • No generation of acetic acid • Non-yellowing Figure 4: „PID Zero“Diamond DESERT Foil vs. „PID Free“ EVA Film J.v.G.
