Automated Pixel Selection for J—V Characterisation of 8-PixeI Perovskite Solar Cells
A manual rotary switch selected which of eight perovskite pixels reached the SourceMeter, so every J–V sweep needed an operator at the bench. I replaced it with eight optically isolated photo-MOSFET relays driven by an Arduino, controlled from the same Python session that runs the instrument. Two earlier designs failed instructively — a CMOS multiplexer whose 70 Ω on-resistance exceeded the source's compliance headroom, and a precision multiplexer that leaked through its own protection diodes. The relay's 20 mΩ makes the switch invisible by construction. Validated against a no-switch control: run-to-run differences are dominated by device drift, not by the hardware.
