The transient photovoltaic (PV) characteristic of HgCdTe PV array is studied using an ultrafast laser. The photoresponse shows an apparent negative valley first. then it evolves into a positive peak. By employing a combined theoretical model of pn junction and Schottky potential. https://www.lightemupsequences.com/flash-pick-Tiki-Luau-Shaped-Thank-You-Cards-Tropical-Hawaiian-Summer-Party-Thank-You-Note-Cards-with-Envelopes-Set-of-12-top-super
