Decoding Trap States in Working 2D Perovskite Multi‐Functional Devices

open access: yesAdvanced Science, EarlyView.
Illustration of the photoluminescence spectrum and energy‐level landscape governing trap‐mediated carrier dynamics in 2D F‐PEAI photodetectors. A novel approach capturing dynamic trap occupation and retrapping in devices under operating conditions, directly links defect energetics to carrier transport and enhanced photoresponse in multifunctional ...

Imidazole Post‐Treated Self‐Assembled Monolayers for Inverted Perovskite Solar Cells

open access: yesAdvanced Science, EarlyView.
A post‐treatment strategy using imidazole derivatives (4,5‐DI and 4,5‐D‐2‐MI) enhances the Me‐4PACz/perovskite interface by improving wettability, promoting perovskite films, and optimizing energy level alignment, resulting in higher efficiency and improved stability in inverted perovskite solar cells.

Defect Dynamics and Solution‐Processed Interconnects in Perovskite‐Organic Tandem Solar Cells

open access: yesAdvanced Science, EarlyView.
In this study, we identify the underlying cause of efficiency losses in WBG perovskites, which is ascribed to the presence of mobile defects distributed at surface regions. We further employ effective passivation agent with functional chemical groups to facilitate the healing of the mobile defects, thereby enhancing the VOC to 1.35 V and champion ...

Synergistic Effects of Additive Engineering in Enhancing the Performance of Sn–Pb Perovskite Thin‐Film Transistors and Derived Logic Circuits

open access: yesAdvanced Science, EarlyView.
An additive engineering strategy employing 4,8‐dihydrobenzo[1,2‐b:4,5‐b′]dithiophen‐4,8‐dione (BDTD) is utilized to passivate bulk defects, regulate crystallization dynamics, and suppress Sn4+ formation in Sn–Pb perovskite thin‐film transistors. The incorporation of BDTD yields a substantial enhancement in electrical performance, increasing the hole ...

Enhanced Bandgap Flexibility in Perovskite‐Silicon Tandem Solar Cells via Three‐Terminal Architecture

open access: yesAdvanced Science, EarlyView.
Three‐terminal (3T) perovskite/silicon tandem solar cells overcome the current‐matching constraints of 2T designs. Using an IBC POLO silicon bottom cell, we demonstrate a 30.1% PCE, with performance largely decoupled from perovskite bandgap and enhanced resilience under realistic, time‐dependent solar spectra.
