Here, temperature is controlled by using a flow through jacketed ART crystal (PIKE Technologies) and a refrigerated/heated circulator (Julabo). Relative humidity is introduced by passing a controlled dry air flow through water bubbler and continually monitored via RH sensor attached to the reaction chamber. Simulated sun light (~ 1 sun)  is provided using a 150 W xenon solar simulator (Newport).
