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.Researchers at the Indian Institute of Technology Bombay have fabricated a transparent four-terminal (4T) perovskite solar cell based on a hole transport layer (HTL) ...
