Figure 3From: Semitransparent inverted polymer solar cells employing a sol-gel-derived TiO2 electron-selective layer on FTO and MoO3/Ag/MoO3 transparent electrodeResistivity of ITO and FTO substrates after annealing treatment at different temperatures. T =20°C, 100°C, 200°C, 300°C, 400°C, and 500°C for 30 min. The inset shows the corresponding square resistance.Back to article page
