Investigation of Annealing and Blend Concentration Effects of Organic Solar Cells Composed of Small Organic Dye and Fullerene Derivative

<table>EQE spectra of the ITO/PEDOT:PSS/C6:PCBM/Al solar cell under thermal treatment before Al deposition at 100°C for 10 min (preannealing) and under subsequent treatments; preannealing (at 100°C for 10 min) followed by annealing after Al deposition (postannealing) at different temperatures.</table>
