Solution-processable electronic devices are highly desirable due to their low cost and compatibility with flexible substrates. However, they often challenging fabricate the hydrophobic nature of surfaces constituent layers. Here, we use a protein solution modify surface properties improve wettability fluoropolymer dielectric Cytop. The engineered hydrophilic is successfully incorporated in bottom-gate solution-deposited organic field-effect transistors (OFETs) hybrid organic-inorganic...
Abstract n‐Doping electron‐transport layers (ETLs) increases their conductivity and improves electron injection into organic light‐emitting diodes (OLEDs). Because of the low affinity large bandgaps ETLs used in green blue OLEDs, n‐doping has been notoriously more difficult for these materials. In this work, polymer poly[(9,9‐dioctylfluorene‐2,7‐diyl)‐ alt ‐(benzo[2,1,3]thiadiazol‐4,7‐diyl)] (F8BT) is demonstrated via solution processing, using air‐stable n‐dopant...
2D polymers (2DPs) are promising as structurally well-defined, permanently porous, organic semiconductors. However, 2DPs nearly always isolated closed shell species with limited charge carriers, which leads to low bulk conductivities. Here, the conductivity of two naphthalene diimide (NDI)-containing 2DP semiconductors is enhanced by controllably n-doping NDI units using cobaltocene (CoCp2 ). Optical and transient microwave spectroscopy reveal that both as-prepared NDI-containing...
Transparent photovoltaic cells are an emerging technology that can provide point-of-use electricity generation for building-integrated applications. While most transparent solar to date target absorption of the photon-rich near-infrared portion spectrum, these devices compromise color neutrality and transparency because parasitic long-wavelength visible light. One solution eliminate is employ materials absorb near-ultraviolet light with sharper cutoffs. Herein, we demonstrate organic donor...
To accelerate materials discovery, computational methods such as inverse design, are used to design UV-absorbing coronene based derivatives that, following synthesis achieve high open-circuit voltages and visible transparencies.
Singlet fission can split a high energy singlet exciton and generate two lower triplet excitons. This process has shown near 200 percent yield. Sensitizing solar cells with material, it potentially increase the power conversion efficiency limit from 29 to 35 percent. in tetracene is known be efficient, of excitons are energetically matched silicon bandgap. In this work, we designed an optical measurement external magnetic field determine efficiencies transfer silicon. Using method, have...
In the standard configurations of metal halide perovskite solar cell, active layer, or absorber, follows a p-i-n n-i-p electronic structure that is designed to enhance separation and extraction photo-induced charge carriers. The control Fermi level position across film, between electron hole transport layers, therefore paramount importance. Direct localized doping in perovskites being still elusive, design structures has so far relied predominantly on surface interface as well work function...
Doping has proven to be a critical tool for enhancing the performance of organic semiconductors in devices like light-emitting diodes. However, challenge working with high-ionization-energy (IE) is find p-dopants correspondingly high electron affinity (EA) that will improve conductivity and charge carrier transport film. Here, we use an oxidant been recently recognized very strong p-type dopant, hexacyano-1,2,3-trimethylene-cyclopropane (CN6-CP). The EA CN6-CP previously estimated via cyclic...
