Dual‐Function Interface Engineering for δ‐Phase‐Free Crystallization Toward Efficient and Stable FAPbI3 Perovskite Solar Cells

Advanced Functional Materials, EarlyView.
This work presents a dual‐function interface engineering strategy using PEACl to suppress the formation of the non‐perovskite δ‐FAPbI3 phase at the critical SnO2 buried interface. This approach enables the direct crystallization of the photoactive α‐phase, yielding highly efficient and stable rigid (25.6%) and flexible perovskite solar cells with ...

Demand side management in the distribution system with photovoltaic generation

Tehnicki vjesnik-Technical Gazette, 2015
In the last years, there was a great effort on inclusion electricity generation from the renewable energy sources in power system. Random renewable generation creates the imbalance between electricity production and consumption, which requires power plants with fast response and also storage systems.

Application of Photovoltaic Power Optimizer in Distributed Photovoltaic Power Generation System

DEStech Transactions on Engineering and Technology Research, 2018
Compared with centralized photovoltaic power generation systems, the distributed generation system's power generation conditions are more complex and changeable, and are extremely susceptible to environmental impacts. To study the mismatch problem of distributed generation systems, a parallel-connected single-switch photovoltaic optimizer circuit was ...

Self‐Adaptive Anhydrous Passivation Mitigates Open‐Circuit Voltage Loss in Pb‐Sn Mixed Perovskite Solar Cells

Advanced Functional Materials, EarlyView.
In this report, a self‐adaptive anhydrous passivation strategy is introduced by incorporating trimellitic anhydride (TMAH) into the perovskite precursor. In situ hydrolysis of TMAH yields trimellitic acid (TMA); ‐C═O/‐COO− groups of TMAH/TMA form a chelate with undercoordinated Pb2+/Sn2+, regulate nucleation, promote (100) orientation, passivate ...
