In this Science paper (Science, 2026, DOI: 10.1126/science.aea3339), the authors claim that the devices retained 90% of their initial power conversion efficiency (27.1%) after approximately 5,000 hours of maximum power point tracking (MPPT) at 85 °C in ambient air. Figure 4a presents the long-term thermal stability of the control and target devices measured under continuous 1-sun equivalent illumination at 85 °C and 50% relative humidity.

A serious concern arises from the apparent duplication of data in Figure 4a. The duplicated regions, highlighted by the blue (Time range: 2060- 3060 h) and purple rectangles (Time range: 3020- 4020 h) below, exhibit strikingly similar features that would not be expected from independent long-term stability measurements. This raises significant concerns regarding the reliability of the reported stability results that claim that the target devices maintained stable performance for more than 5,000 hours. The authors should provide the original raw MPPT datasets and a detailed explanation for the observed duplication.
