Inert Atmosphere Gloveboxes for Perovskite Solar Cell and OPV Research

Perovskite photovoltaics have advanced from laboratory curiosity to a credible rival to silicon in under fifteen years — driven almost entirely by improvements in synthesis control, interface engineering, and encapsulation. At the heart of this progress is the inert atmosphere glovebox, which provides the controlled environment in which these exceptionally moisture- and oxygen-sensitive materials can be deposited, characterised, and tested without degradation.

LABPRO glovebox systems are actively used in perovskite PV and organic photovoltaic (OPV) research at universities and institutes across India and internationally. Our systems maintain the sub-1 ppm oxygen and moisture atmospheres that perovskite researchers require, while offering the process tool integration — spin coaters, thermal evaporators, hotplates — that modern perovskite workflows demand.

​

Why Perovskite Materials Require Strict Atmosphere Control?

​

Organometal halide perovskites — including MAPbI₃, FAPbI₃, and their mixed-halide variants — are inherently unstable in moisture and oxygen. Water molecules disrupt the crystal structure at grain boundaries, converting the photoactive black phase of MAPbI₃ to the inactive yellow phase within minutes under ambient conditions. For lead-free alternatives such as tin-based perovskites, instability is still more pronounced: tin(II) oxidises to tin(IV) within seconds of air exposure, collapsing device performance entirely.

Maintaining O₂ and H₂O below 1 ppm throughout deposition, annealing, and characterisation is the prerequisite for achieving the film quality that leads to high-efficiency devices and reproducible publications.​

​

Perovskite Processes Performed in LABPRO Gloveboxes

• Solution-processed deposition: spin coating of perovskite precursor solutions, hole transport layers (Spiro-OMeTAD, PTAA), and electron transport layers under inert atmosphere.

• Thermal annealing: controlled crystallisation of perovskite films on integrated hotplates, with continuous atmosphere monitoring.

• Vacuum deposition: co-evaporation of PbI₂ and MAI for vapour-phase perovskite synthesis; metal contact evaporation (Au, Ag, Al).

• Encapsulation: application of edge-seal adhesives and cover glass under inert atmosphere before atmospheric exposure.

• Device characterisation: J-V measurements, EQE, and stability testing to isolate intrinsic from environmental degradation.

• OPV and OLED fabrication: organic semiconductor layers, buffer layers, and transparent contacts for organic photovoltaic and light-emitting devices.

Critical: solvent trapping for DMF, DMSO, and chlorobenzene workflows 

Perovskite precursor solutions routinely use DMF, DMSO, and chlorobenzene (CB). Without solvent trapping, these compounds accumulate in the glovebox atmosphere and contaminate the purification catalyst, degrading O₂ and H₂O performance over time. LABPRO systems are available with automated regenerable solvent traps with integrated solvent sensors, protecting purification performance and extending catalyst lifetime significantly.

Scalable Systems: From Single-Junction Research to Tandem Cell Development

Entry-level perovskite research typically requires a single 1250 mm workstation with spin coater integration and a thermal evaporator interface for contact deposition. As programmes scale toward tandem cell development — combining silicon or CIGS bottom cells with perovskite top cells — LABPRO's modular design allows seamless expansion. Large-volume systems for industrial-scale substrate handling and custom multi-chamber systems with separated deposition and characterisation zones are available
