This Design Idea presents a low power short circuit finder that capitalizes on the ear’s sensitivity to changes in frequency. The heart of the circuit is a voltage-to-frequency converter (based on ...

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.

The Chinese manufacturer said its Bycium+ PV cell achieved an open-circuit voltage of 748.6 mV. The result was confirmed by Germany’s Institute for Solar Energy Research in Hamelin.
