Glove Boxes (equipped with spin-coater and thermal vacuum evaporator)

Glove boxNitrogen-filled glove boxes, equipped with a spin-coater, a metal/metal-oxide/organic thermal vacuum evaporation system, as well as a photovoltaic characterization set up. An A.M. 1.5G simulated solar light is coupled into the glove box from an Oriel solar simulator (Oriel Sol3A Class AAA) to characterize the current-voltage characteristics of organic solar cells (OPVs). Similarly, the glove box OPV measurement system is capable of characterizing an external quantum efficiency of solar cells.



Organic Molecular Beam Deposition

We operate two chambers for molecular beam deposition of organic molecules. Each is equipped with a turbo pump to facilitate molecular sublimation under pressure around 10^-7 Torr. The organic molecules are heated in a crucible wrapped by a tungsten wire that is powered by an external power source, while the desired substrate is positioned above the source. Flux is controlled by a manual shutter and monitored during deposition by a quartz crystal microbalance.
