A). Phase separation and morphology in nanotube blends are poorly understood. 3 Hybrid Organic/Inorganic Nanocomposites Attempts to merge inorganic with organic photovoltaic technology are often undermined by solubility and processing difficulties. Two techniques are being explored as possible solutions. The first deposits porous inorganic architectures, subsequently intercalating polythiophene. The second method deposits a suspension of stabilized inorganic nanoparticles or nanorods in polymer solution.

Annealing at high temperature developed the 1 0 0 peak in all fractions [92]. 09 eV absorption. 5 Benefits of HT-Regioregular Polythiophenes in Solar Cells promotes formation of nanocrystalline domains in solution that may template further organization on drying. 2 HT-PT Electron Transport: Conductivity and Mobility Conductivity in organic semiconductors depends on generating efficient pathways through the bulk. 0 S cmÀ1 when doped with iodine. In contrast, HT-PATconductivities typically are s ¼ 100–200 S cmÀ1 with some samples as high as 1000 S cmÀ1 [2–4].

A larger proportion of amorphous material remains because longer molecules with poorly mobile, entangled chains do not assemble as quickly. Chains at least Mn ¼ 12 800 ($77 rings) were necessary to maintain solar cell performance. 4 Evolution of Short-Circuit Current Short-circuit current density/current ( Jsc, Isc) depends on the efficiency of charge separation, scaling with the area of the donor/acceptor interface where this process occurs [123]. However, a reliable estimation of interface area remains elusive.
