Record Open-Circuit Voltage in Perovskite/PERC Tandem Solar Cells via Novel a-Si Interlayer Passivation.

Monolithic perovskite/silicon tandem (PST) solar cells are rapidly emerging as next-generation solar cells with significant potential for commercialization. This study presents a proof of concept for a silicon diffused junction-based PST cell, utilizing a passivated emitter rear contact (PERC) cell with a low-temperature (<200 °C) laser-fired contact process to minimize thermal damage. By introducing amorphous silicon to the emitter surface of PERC bottom cell, the open circuit voltage (V) improve from 0.

Phase-Tuned MoS and Its Hybridization with Perovskite Oxide as Bifunctional Catalyst: A Rationale for Highly Stable and Efficient Water Splitting.

The efficient realization of bifunctional catalysts has immense opportunities in energy conversion technologies such as water splitting. Transition metal dichalcogenides (TMDs) are considered excellent hydrogen evolution catalysts owing to their hierarchical atomic-scale layered structure and feasible phase transition. On the other hand, for efficient oxygen evolution, perovskite oxides offer the best performance based on their rational design and flexible compositional structure.
