Wafer‐Scale Room‐Temperature Processing of Lead‐Free Perovskites for Optoelectronic Applications

Advanced Science, EarlyView.
We present the first wafer‐scale, room‐temperature synthesis of lead‐free Cs3Sb2X9 (X = Br, I) perovskite films via solvent‐free magnetron sputtering. The resulting high‐performance photodetectors achieve benchmark responsivity, bandwidth, and detectivity, enabling scalable manufacturing for next‐generation optoelectronics.

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

Advanced 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

Advanced 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

Advanced 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

Advanced 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.
