Colloidal Quantum Dot Tandem Solar Cells Using CVD Graphene as An Atomically Thin Intermediate Recombination Layer
(ACS, 2018-06-28)
Article
Open AccessTwo-terminal tandem cell architectures are believed to be an effective way to further improve the power conversion efficiency in solution processed photovoltaics. To design an efficient tandem solar cell, two key issues ... -
High Efficiency Colloidal Quantum Dot Infrared Light Emitting Diodes via Engineering at the Supra-Nanocrystalline Level
(Nature, 2018-12-03)
Article
Open AccessColloidal quantum dot (CQD) light-emitting diodes (LEDs) deliver a compelling performance in the visible, yet infrared CQD LEDs underperform their visible-emitting counterparts, largely due to their low photoluminescence ... -
High-Efficiency Light-Emitting Diodes Based on Formamidinium Lead Bromide Nanocrystals and solution processed transport layers
(ACS, 2018-09-11)
Article
Open AccessPerovskite nanocrystal light-emitting diodes (LEDs) employing architecture comprising a ZnO nanoparticles electron-transport layer and a conjugated polymer hole-transport layer have been fabricated. The obtained LEDs ... -
Infrared Solution‐Processed Quantum Dot Solar Cells Reaching External Quantum Efficiency of 80% at 1.35 µm and Jsc in Excess of 34 mA cm−2
(Wiley, 2018-01-08)
Article
Open AccessDeveloping low‐cost photovoltaic absorbers that can harvest the short‐wave infrared (SWIR) part of the solar spectrum, which remains unharnessed by current Si‐based and perovskite photovoltaic technologies, is a prerequisite ... -
Low-Cost RoHS Compliant Solution Processed Photovoltaics Enabled by Ambient Condition Synthesis of AgBiS2 Nanocrystals
(ACS, 2020-03-04)
Article
Open AccessTwo major challenges exist before colloidal nanocrystal solar cells can take their place in the market: So far, these devices are based on Pb/Cd-containing nanocrystals, and second, the synthesis of these nanocrystals takes ... -
Low-temperature colloidal synthesis of CuBiS2 nanocrystals for optoelectronic devices
(Royal Society of Chemistry, 2017-11-11)
Article
Open AccessA new facile colloidal synthesis of CuBiS2 (CBS) nanocrystals with monodispersed size and good quality has been developed. The CBS nanocrystal films was deposited by solid-state ligand exchange and their field effect ... -
Trap-state suppression and improved charge transport in PbS quantum dot solar cells with synergistic mixed ligand treatments
(Wiley, 2017-04-12)
Article
Open AccessThe power conversion efficiency of colloidal PbS‐quantum‐dot (QD)‐based solar cells is significantly hampered by lower‐than‐expected open circuit voltage (VOC). The VOC deficit is considerably higher in QD‐based solar cells ...
