Color temperature of electroluminescence from white light-emitting electrochemical cells can be adjusted by locally laser-scanned thermal annealing on a semi-continuous thin Ag film embedded between indium tin oxide anode and glass substrate. The proposed technique offers programmable versatility to control white electroluminescence and is compatible with display manufacturing technologies.
To date, small molecule-based organic solar cells (SMOSCs) using p-type small molecules and n-type fullerenes have achieved remarkable PCEs by using either solution-processed or vacuum-deposited fabrication techniques. The search for new donor materials with promising physical properties has taken the center stage. Along this line, a large number of donor molecules with interesting molecular architectures...
In this letter, the authors present a highly efficient small-molecule organic photovoltaic (OPV) with a donor-acceptor bulk-heterojunction of a novel electron donor material and C70. As a result, the OPV exhibited a highest power conversion efficiency of 6.8%, an open circuit voltage of 0.79 V, a short-circuit current density of 16.13 mA/cm2 and a fill factor (FF) of 53.9 % under 1 sun solar illumination...
We have demonstrated a small molecule organic solar cell with a novel electron donor material based on donor-acceptor-acceptor (D-A-A) backbone. In such a device, 2.32%, 0.92 V, and 4.80 mA/cm2 in power conversion efficiency, open circuit voltage, and short circuit current density, respectively, was achieved with planar mix bulk heterojunction structure combined with C60 as the electron acceptor.
Dye-sensitized solar cells (DSSCs) are emerging as one promising solar cell technology. A DSSC consists of transparent conductive substrate, a nano-porous TiO2 nanoparticle photoelectrode, dye, electrolyte, and a counter electrode, which are all crucial on overall cell efficiency. This paper will focus on development of nanostructures for various parts of the devices and novel organic dyes for efficient...
