P-N junction

P-N junction

A p-n junction is formed when p-type and n-type semiconductor materials are joined together. At the interface of the p-n junction, holes from the p-side and electrons from the n-side begin to diffuse into the opposite sides due to the concentration gradient. This diffusion of carriers leads to a region around the junction where there are no free charge carriers, known as the depletion region. The charge density within the depletion region for the n-side and p-side can be described by the...

Background:

Inverted (p-i-n) perovskite solar cells (PSCs) offer advantages like low-temperature processing and tandem compatibility.
Self-assembled monolayers (SAMs), such as MeO-4PACz, are crucial for efficient hole extraction in PSCs.
Limitations in interfacial energetics and defect passivation of current SAMs hinder further performance improvements.

Purpose of the Study:

To engineer dipole-modulated SAMs by incorporating 3-BPIC-F into MeO-4PACz.
To investigate the impact of 3-BPIC-F on interfacial properties and defect passivation in PSCs.
To enhance the power conversion efficiency (PCE) and operational stability of inverted wide-bandgap PSCs.

Main Methods:

Construction of dipole-modulated SAMs using 3-BPIC-F and MeO-4PACz.
Systematic characterization of interfacial energetics, dipole strength, and energy-level alignment.
Evaluation of defect reduction in perovskite layers and assessment of hole extraction efficiency.

Main Results:

Introduction of 3-BPIC-F significantly enhanced interfacial dipole strength and optimized energy-level alignment.
Effective reduction of defects in perovskite layers led to suppressed nonradiative recombination.
Power conversion efficiency (PCE) of small-area inverted wide-bandgap PSCs increased from 21.97% to 23.64%, with improved open-circuit voltage and fill factor.

Conclusions:

3-BPIC-F modified MeO-4PACz SAMs provide a viable strategy for interfacial engineering in PSCs.
The enhanced SAMs facilitate selective hole extraction and suppress internal nonradiative recombination.
Module-level validation demonstrated a PCE increase from 16.43% to 19.80%, confirming scalability and practical potential.
