Depending on battery voltage, that threshold may even be 80Ω. The tester’s open-circuit voltage is less than 0.5V. Its short-circuit current is approximately 1 mA. Values are low so that the tester ...

This Design Idea is for an in-circuit tester which can be clipped onto each of the PROMs without removing them from the board. There is a test point on the PCB which disables the address drivers to ...

Further details of the setup and the results are provided in the study “ Outdoor implied open-circuit voltage imaging of perovskite solar cells using sunlight excitation,” published in Joule.
