Development and Application of a Reconfigurable Photovoltaic Inverter for Operation Within a Microgrid [PDF]

IEEE Access, 2019
Smart grids have their basis in distribution systems, and to take advantage of their full potential, the incorporation of distributed generation must be taken into account. This new strategy allows the decentralization of power generation and the microgrid represents a very important element in this generation scheme.

Dry‑Contact Trimming for All‑Perovskite Tandem Solar Cells via Solid‑Solution Homogenization

Advanced Energy Materials, EarlyView.
Narrow‐bandgap Sn–Pb perovskites are promising bottom absorbers for all‐perovskite tandems but suffer from Sn‐rich surfaces and depth‐dependent lattice/compositional inhomogeneity. Layered‐perovskite‐assisted dry‐contact trimming removes Sn‐rich surface species and reconfigures the Sn–Pb absorber, enabling efficient charge collection, reduced voltage ...
