Bright and efficient blue polymer light emitting diodes with reduced operating voltages processed entirely at low-temperature
Hoye, Robert L. Z.; Musselman, Kevin P.; Chua, M. R.; Sadhanala, Aditya; Raninga, R. D.; MacManus-Driscoll, Judith L.; Friend, Richard H.; Credgington, Dan (Royal Society of Chemistry, 2015-09-03)Hybrid blue polymer light emitting diodes (PLEDs) with high efficiencies, luminance >20 000 cd m−2 and low operating voltages are obtained using processing temperatures ≤150 °C. By briefly applying an electric field across ... -
Fabrication of ZnO/Cu2O heterojunctions in atmospheric conditions: Improved interface quality and solar cell performance
levskaya, Yulia; Hoye, Robert L. Z.; Sadhanala, Aditya; Musselman, Kevin P.; MacManus-Driscoll, Judith L. (Elsevier, 2015-04-01)Zn1−xMgxO/Cu2O heterojunctions were successfully fabricated in open-air at low temperatures via atmospheric atomic layer deposition of Zn1−xMgxO on thermally oxidized cuprous oxide. Solar cells employing these heterojunctions ... -
Improved Heterojunction Quality in Cu2O-based Solar Cells Through the Optimization of Atmospheric Pressure Spatial Atomic Layer Deposited Zn1-xMgxO
Ievskaya, Yulia; Hoye, Robert L. Z.; Sadhanala, Aditya; Musselman, Kevin P.; MacManus-Driscoll, Judith L. (Journal of Visualized Experiments, 2016-07-01)Atmospheric pressure spatial atomic layer deposition (AP-SALD) was used to deposit n-type ZnO and Zn1-xMgxO thin films onto p-type thermally oxidized Cu2O substrates outside vacuum at low temperature. The performance of ... -
Nanostructured conformal hybrid solar cells: a promising architecture towards complete charge collection and light absorption
Iza, Diana C.; Munoz-Rojas, David; Musselman, Kevin P.; Weickert, Jonas; Jakowetz, Andreas C.; Sun, Haiyan; Ren, Xin; Hoye, Robert L. Z.; Lee, Joon H.; Wang, Haiyan; Schmidt-Mende, Lukas; MacManus-Driscoll, Judith L. (Springer, 2013-08-22)We introduce hybrid solar cells with an architecture consisting of an electrodeposited ZnO nanorod array (NRA) coated with a conformal thin layer (< 50 nm) of organic polymer-fullerene blend and a quasi-conformal Ag top ... -
Perspective: Maintaining surface-phase purity is key to efficient open air fabricated cuprous oxide solar cells
Hoye, Robert L. Z.; Brandt, Riley E.; Ievskaya, Yulia; Heffernan, Shane; Musselman, Kevin P.; Buonassisi, Tonio; MacManus-Driscoll, Judith L. (AIP Publishing, 2015-02-01)Electrochemically deposited Cu2O solar cells are receiving growing attention owing to a recent doubling in efficiency. This was enabled by the controlled chemical environment used in depositing doped ZnO layers by atomic ... -
Research Update: Doping ZnO and TiO2 for solar cells
Hoye, Robert L. Z.; Musselman, Kevin P.; MacManus-Driscoll, Judith L. (AIP Publishing, 2013-12-01)ZnO and TiO2 are two of the most commonly used n-type metal oxide semiconductors in new generation solar cells due to their abundance, low-cost, and stability. ZnO and TiO2 can be used as active layers, photoanodes, buffer ...
