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:

Commercialization of perovskite solar cells (PSCs) is limited by interfacial instability.
Organic passivation layers degrade, accelerating device performance decay.

Purpose of the Study:

To develop a stabilization strategy for inverted PSCs.
To enhance the operational stability and efficiency of PSC devices.

Main Methods:

Introduction of an ultrathin interlayer of inert alkaline-earth metal fluorides.
Placement of the interlayer between the passivation layer and the electron-transport layer.
Characterization of interfacial properties and device performance.

Main Results:

The interlayer homogenizes interfacial contact-potential distribution without hindering transport properties.
The inert interlayer preserves interfacial integrity and prevents detrimental reactions.
Devices achieved power-conversion efficiencies exceeding 26% and retained over 91% efficiency after 1000 hours.

Conclusions:

The ultrathin inert-interlayer approach provides a scalable pathway for highly efficient and durable inverted PSCs.
This strategy effectively addresses interfacial degradation issues in PSCs.
The CaF2 interlayer significantly improves operational stability.
