WebJun 7, 2024 · In this article, the importance of the High Humidity, High Temperature and High Voltage Reverse Bias test (H3TRB-HVDC) for semiconductor reliability is shown. With the test methodology presented here, long term ruggedness of SiC-based semiconductors to harsh environmental conditions is assessed. To demonstrate the importance of the test … WebWe show that reverse bias events in which a perovskite cell is biased above a threshold voltage—which in this work we find to be as low as −1.1 V—produces a temporary reduction in power output that is of sufficient …
