P-N junction01:11

P-N junction

1.5K
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...

Area of Science:

  • Materials Science
  • Renewable Energy

Background:

  • Formamidinium lead iodide (FAPbI3) perovskite solar cells (PSCs) offer higher efficiency than methylammonium lead iodide (MAPbI3) PSCs.
  • Air fabrication of FAPbI3 PSCs faces stability and reproducibility issues due to residual hygroscopic solvents and rapid FAI/PbI2 reactions.

Purpose of the Study:

  • To enhance the stability and efficiency of air-processed FAPbI3 PSCs.
  • To address challenges in perovskite crystallization and PbI2 residue during fabrication.

Main Methods:

  • Introduced thiacetazone as an additive to the PbI2 precursor solution.
  • Thiacetazone interacts with PbI2 to reduce PbI2·xDMSO complexes and moderates the FAI/PbI2 reaction rate.
  • Formed a mesoporous film facilitating organic ammonium salt permeation and passivating defects.

Main Results:

  • Achieved a record power conversion efficiency (PCE) of 26.52% for air-processed n-i-p PSCs.
  • Maintained a high PCE of 23.24% when fabricated under 70% relative humidity (RH).
  • Unencapsulated devices retained 92% of initial PCE after 180 days in ambient air (30-40% RH).

Conclusions:

  • Thiacetazone additive significantly improves FAPbI3 PSC crystallization, reduces PbI2 residue, and passivates defects.
  • This strategy enables efficient and storage-stable PSCs fabricated under ambient humidity conditions.
  • Offers a promising route for scalable and durable perovskite solar cell technology.
