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.

Cation–Anion Synergy Enables Uniform and Stable SAMs for High‐Efficiency Perovskite/TOPCon Tandem Solar Cells

Advanced Science, EarlyView.
A cation‐anion synergistic strategy is developed to enhance self‐assembled monolayer (SAM) adsorption using guanidinium thiocyanate (GuaSCN). Guanidinium (Gua⁺) suppresses micelle aggregation, while thiocyanate (SCN−) promotes phosphonic acid deprotonation and strengthens ionic bonding to the substrate.
