The total lab space for Huang’s group at this time is approximately 1,500 square feet. We have already established a world-class facility for organic/nano electronic material synthesis, material characterization, device fabrication, and device characterization.
A double length MBraun glove box is available to do the spin-coating in the N2 atmosphere. The glove box has also the quartz windows and electric feedthroughs which allow I-V measurement of the solar cell devices inside the glove box. A Newport 150 W solar simulator and computer controlled Keithley 2400 for solar cell efficiency measurement is available.
One glovebox with a SCS G-8 spin-coater intergrated.
One MBraun four-source thermal evaporator in the glovebox which connected to the spin-coater glovebox. Co-evaporation can be done in this evaporator.
A Vigor glovebox with SCS 6808P spin-coater inside
N2 filled glovebox with KW 4A spin-coater for film deposition, several hotplates/stirrers for annealing.
Material/substrate preparing equipment includes two hoods for chemical synthesis, Jelight UV-Ozone for substrate surface treatment, KW 4A spin-coater for film deposition, several hotplates/stirrers and several ovens for annealing.
The vertical laminar flow workstation provides clean laminar flow air for process protection by using a two stage filtration process. Room air is first cleaned with an electrostatically charged prefilter and then further cleaned with a HEPA filter.
A Newport optical table for external quantum efficiency (IPCE) and Photoluminescence spectroscopy measurements.
