Conjugated Polymer Photovoltaic Cells
Conjugated polymers are attractive semiconductors for photovoltaic cells because they are strong absorbers and can be deposited on flexible substrates at low cost. Cells made with a single polymer
Accounting for Interference, Scattering, and Electrode Absorption to Make Accurate Internal Quantum Efficiency Measurements in Organic and Other Thin Solar Cells
TLDR
It is shown that for typical OPVs, precise knowledge of the real part of the complex index of refraction is not required for the active layer absorption, and it is critically important to take this parasitic absorption into account when calculating internal quantum effi ciency.
Liquid-crystalline semiconducting polymers with high charge-carrier mobility
TLDR
New semiconducting liquid-crystalline thieno[3,2-b ]thiophene polymers are reported on, the enhancement in charge-carrier mobility achieved through highly organized morphology from processing in the mesophase, and the effects of exposure to both ambient and low-humidity air on the performance of transistor devices.
FROM SYNTHESIS TO PROPERTIES AND APPLICATIONS
Copper-based ATRP (atom transfer radical polymerization) catalytic systems with polydentate nitrogen-based ligands is among most efficient controlled/living radical polymerization systems. 1
Semi-transparent perovskite solar cells for tandems with silicon and CIGS
A promising approach for upgrading the performance of an established low-bandgap solar technology without adding much cost is to deposit a high bandgap polycrystalline semiconductor on top to make a
Smooth Nanowire/Polymer Composite Transparent Electrodes
TLDR
This work focuses on replacing conductive metal oxides with alternative materials that can be deposited from solution and can reproduce the performance of metal oxide on glass on various substrates, including plastics.
Highly oriented crystals at the buried interface in polythiophene thin-film transistors
Thin films of polymer semiconductors are being intensively investigated for large-area electronics applications such as light-emitting diodes, photovoltaic cells and thin-film transistors.
The Mechanism of Burn‐in Loss in a High Efficiency Polymer Solar Cell
Degradation in a high efficiency polymer solar cell is caused by the formation of states in the bandgap. These states increase the energetic disorder in the system. The power conversion efficiency
Efficient charge generation by relaxed charge-transfer states at organic interfaces.
TLDR
For a wide range of photovoltaic devices based on polymer:fullerene, small-molecule:C60 and polymer:polymer blends, the study reveals that the internal quantum efficiency is essentially independent of whether or not D, A or CT states with an energy higher than that of CT1 are excited.
