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:

Tin-based perovskite solar cells (TPSCs) offer eco-friendliness and high efficiency potential.
Sn²⁺ oxidation in TPSCs leads to defects, hindering charge transport and device performance.

Purpose of the Study:

To investigate the use of imine-linked donor-acceptor covalent organic frameworks (COFs) as precursor additives in TPSCs.
To address Sn²⁺ oxidation and defect passivation challenges in tin-based perovskite solar cells.

Main Methods:

Synthesized and utilized two COFs, BCTB-BTD-COF and BCTB-BSD-COF, as additives in TPSC fabrication.
Evaluated the impact of COFs on Sn²⁺ oxidation suppression, defect passivation, and device performance metrics.

Main Results:

Both COFs effectively suppressed Sn²⁺ oxidation and passivated defects.
BCTB-BSD-COF demonstrated superior performance via multidentate chelation, improving defect passivation and energy-level alignment.
TPSCs with BCTB-BSD-COF achieved a champion power conversion efficiency of 16.29% and retained 85% efficiency after 35 days.

Conclusions:

Covalent organic frameworks (COFs) present a novel strategy for defect passivation in tin-based perovskite solar cells.
The use of BCTB-BSD-COF as an additive significantly enhances TPSC performance and stability.
This approach offers a promising route towards high-efficiency and stable tin-based perovskite solar cells.
