Perovskite Automated Spin Coat Assembly Line (PASCAL)
Motivation
PASCAL is an automated platform for spin coating and annealing thin films onto small (>2x2 cm) substrates, aimed af increasing experimental throughput in the pursuit of designing better perovskite solar cells. Perovskite solar cells are infinitely tunable, as they can be formed with combinations of nearly half of the periodic table, presenting the excitement of limitless possibilities and the curse of dimensionality. With PASCAL, we aim to increase our experimental search rate by orders of magnitude, enabling a more systematic and exhaustive approach toward exploring the vast compositional space of interest for solar cell design.
Hardware
CAD schematics of PASCAL
Liquid handler preparing precursor solution mixtures for a compositional search
Liquid handler + spincoater working in conjunction to deposit solution onto substrate.

Experimental Planning
- Computed material properties -> manifold embedding / dimensionality reduction into "behavior space"
Hardware Scheduling
Active Learning
intra-run (narrow scope)
bayesian approach to evaluating sample space
update compositions of interest using in-line during experiment
inter-run (wide scope)
- bayesian approach with operator input (XRD, UV-Vis, etc)
- find covariances between composition/fabrication conditions
- point towards broader design philosophies in perovskite solar cells
In-Line Characterization
Widefield PL camera
RGB Imaging for color determination
Dependency
