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:

Self-assembled monolayers (SAMs) are crucial for hole-selective contacts in perovskite solar cells (PSCs).
Existing SAMs face degradation and aggregation issues during solution-based perovskite deposition, limiting device performance and scalability.
Developing robust interfaces is key for efficient and stable PSCs.

Purpose of the Study:

To introduce a transient 2D perovskite protection strategy to safeguard SAMs during PSC fabrication.
To improve the uniformity of large-area perovskite films and enhance charge extraction.
To demonstrate the scalability and operational stability of PSCs using this protection method.

Main Methods:

Utilized a volatile propylammonium chloride additive to form a transient 2D perovskite layer.
This layer temporarily protected SAMs from solvent-induced degradation during perovskite deposition.
The protective layer was designed to decouple during thermal annealing, preserving the SAM interface.

Main Results:

Achieved a power conversion efficiency (PCE) of 26.14% for small-area (0.05 cm²) PSCs.
Demonstrated scalable efficiencies of 23.27% for a 5 × 5 cm² mini-module and 22.34% for a 30 × 30 cm² module (615.7 cm² active area).
The large-area module maintained 90% of its initial efficiency after 2000 hours of continuous operation, indicating high stability.

Conclusions:

The transient 2D perovskite protection strategy effectively preserves SAM integrity and promotes uniform perovskite crystallization.
This approach enables high-performance, stable, and scalable perovskite solar cells.
Highlights a viable pathway for the reliable commercialization of perovskite photovoltaics.
