제목 Dielectric Effects in Photovoltaic Polymers
초록 In this talk, we will first describe how we used charge modulated electroabsorption spectroscopy (CMEAS) to measure the effective bandgap energy of a polymer-fullerene blend. Knowing the effective bandgap energy in a polymer solar cell, we found that for polymer blends with low dielectric constants, the photo-voltage loss can be as large as 0.35 V. On the other hand, there is no voltage loss if the dielectric constant is close to 5, suggesting that these polymer solar cells behave like their inorganic counter-parts.
