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...

Renewable Energy

Background:

Self-assembled molecular (SAM) hole-transport materials enhance perovskite solar cell efficiency but cause interfacial challenges.
Poor wettability, stability, and nonuniform formation of SAMs hinder device performance and reproducibility.

Purpose of the Study:

To overcome limitations of SAMs in inverted perovskite solar cells.
To introduce d-camphorsulfonic acid (D-CSA) as a multifunctional interfacial modifier.

Main Methods:

D-CSA was used to enhance perovskite precursor wettability on Me-4PACz.
D-CSA passivated Me-4PACz via protonation and coordinated with Pb2+ ions.
Energy level alignment between the hole-transport layer (HTL) and perovskite was optimized.

Main Results:

D-CSA modification improved power conversion efficiency from 23.25% to 25.47% with negligible hysteresis.
Enhanced moisture resistance, thermal stability, and operational stability were observed.
Improved perovskite film quality and charge transport were achieved.

Conclusions:

D-CSA is a feasible strategy for developing highly efficient and stable inverted perovskite solar cells.
Multifunctional interfacial modification with D-CSA addresses key challenges in device development.
