Identification of Model Parameters of the Photovoltaic Solar Cells

Energy Procedia, 2014
AbstractPresently, many equivalent circuit models have been developed and proposed to describe the photovoltaic (PV) cell's characteristics, and the most commonly used are single and double diode models. In a single diode model, a complete characteristic of a PV cell's can be described by five model parameters i.e.: light generated current, leakage or ...

Operation Limits of Integrated Photo‐Rechargeable Batteries

Advanced Materials, EarlyView.
This study elucidates the operational limitations of integrated photo‐rechargeable batteries. We demonstrate that the photo‐charging process is fundamentally restricted not only by material‐to‐material energy level alignment but also by transient capacitive charge accumulation within the cathode framework.

CVD Grown Hybrid MoSe2–WSe2 Lateral/Vertical Heterostructures With Strong Interlayer Exciton Emission

Advanced Materials, EarlyView.
A scalable bottom‐up CVD methodology, based on liquid transition metal salt precursors, is presented for the controlled growth of two high‐quality MoSe2–WSe2 heterostructures (HSs): purely lateral (HS I) and hybrid lateral/vertical (HS II), by simply adjusting precursor concentration.

Deterministic Nucleation of Nanocrystal Superlattices on 2D Perovskites for Light‐Funneling Heterostructures

Advanced Materials, EarlyView.
This work investigates the heterogeneous nucleation of CsPbBr3${\rm CsPbBr}_3$ nanocrystal superlattices along the faces of 2D PEA2PbBr4${\rm PEA}_2{\rm PbBr}_4$ layered perovskite microcrystals. Core–crown and core–shell heterostructure morphologies are obtained.

Asymmetric Lamellar Templating of the Perovskite/C60 Interface for Scalable Inverted Perovskite Photovoltaics

Advanced Materials, EarlyView.
Asymmetric lamellar templating at the perovskite/C60 interface is achieved using a laterally polarized indole spacer. Surface anchoring and Ind–Ind assembly form a π‐rich lamellar interphase that supports uniform C60 contact formation, suppresses recombination, preserves electron extraction, and enables certified high‐efficiency cells and modules with ...
