Thermally stable, efficient polymer solar cells with nanoscale control of the interpenetrating network morphology
By applying the specific fabrication conditions summarized in the Experimental section and post-production annealing at 150 °C, polymer solar cells with power-conversion efficiency approaching 5 %Expand
New Architecture for High‐Efficiency Polymer Photovoltaic Cells Using Solution‐Based Titanium Oxide as an Optical Spacer
reported under AM1.5 (AM: air mass) illumination, this efficiency is not sufficient to meet realistic specifications for commercialization. The need to improve the light-to-electricity conversionExpand
Photovoltaic devices employing ternary PbSxSe1-x nanocrystals.
Crystalline, monodisperse alloyed nanocrystals are obtained using a one-pot, hot injection reaction and Rutherford back scattering and energy-filtered transmission electron microscopy suggest that the S and Se anions are uniformly distributed in the alloy nanoparticles. Expand
Photovoltaic performance of ultrasmall PbSe quantum dots.
The results demonstrate that even in this simple device architecture, fine-tuning of the nanoparticle size can lead to substantial improvements in efficiency. Expand
Effect of the Molecular Weight of Poly(3-hexylthiophene) on the Morphology and Performance of Polymer Bulk Heterojunction Solar Cells
The morphology and performance of bulk heterojunction solar cells comprised of poly(3-hexylthiophene) (P3HT) and [6,6]-phenyl-C 61 butyric acid methyl ester (PCBM) have been investigated using P3HTExpand
Synthesis and photovoltaic application of copper(I) sulfide nanocrystals.
We present the rational synthesis of colloidal copper(I) sulfide nanocrystals and demonstrate their application as an active light absorbing component in combination with CdS nanorods to make aExpand
Perovskite Quantum Dot Solar Cells with 15.6% Efficiency and Improved Stability Enabled by an α-CsPbI3/FAPbI3 Bilayer Structure
We developed lead halide perovskite quantum dot (QD) solar cells with a combinational absorbing layer based on stacked α-CsPbI3 and FAPbI3. α-CsPbI3 QDs, with a relatively wide bandgap of 1.75 eV, ...
Room-Temperature Processed Nb2O5 as the Electron-Transporting Layer for Efficient Planar Perovskite Solar Cells.
Benefitting from the low-temperature process, flexible PSCs based on a-Nb2O5, with a considerable PCE of 12.1%, suggest a great potential for its application in optoelectrical devices. Expand
Ligand Mediated Transformation of Cesium Lead Bromide Perovskite Nanocrystals to Lead Depleted Cs4PbBr6 Nanocrystals.
The results not only shed light on a decomposition pathway of CsPbBr3 NCs but also present a method to synthesize uniform colloidal Cs4Pb Br6 NCs, which may actually be a common product of perovskite NCs degradation. Expand
Additive to regulate the perovskite crystal film growth in planar heterojunction solar cells
We reported a planar heterojunction perovskite solar cell fabricated from MAPbI3−xClx perovskite precursor solution containing 1-chloronaphthalene (CN) additive. The MAPbI3−xClx perovskite films haveExpand
