Indian researchers build transparent perovskite-silicon tandem solar cell with 30.2% efficiency
The transparent four-terminal perovskite solar cell employs an ion-modulated spiro-MeOTAD hole transport layer, which passivates interfacial defects, enhances carrier dynamics, and allows for a tunable work function in wide-bandgap perovskites. When integrated into mechanically stacked 4T tandems with an n-TOPCon cell, the device achieved an overall efficiency of 28.4–30.2%, along with improved open-circuit voltage and fill factor.
Chinese scientists build 31.13%-efficient perovskite-silicon tandem solar cell via 2D seeding agent
Researchers in China developed a novel two dimensional (2D) seeding agent to regulate crystallization in a 1.80-eV wide-bandgap perovskite film. A perovskite-silicon tandem device made with the resulting optimized subcell achieved an efficiency of 31.13%, outperforming a control device.
