P-N junction01:11

P-N junction

438
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
  • Nanotechnology

Background:

  • Inverted perovskite solar cells (PSCs) show rapid advancement, influenced by self-assembled molecules (SAMs).
  • Uniform SAM coverage on substrates is crucial for PSC performance and stability but remains a challenge.
  • Direct contact between perovskite and substrate can lead to defects and reduced device longevity.

Purpose of the Study:

  • To develop a novel SAM for improved perovskite-substrate interfaces in inverted PSCs.
  • To investigate the molecular structure and packing of the new SAM.
  • To evaluate the impact of the SAM on PSC efficiency and long-term stability.

Main Methods:

  • Synthesis and characterization of (4-(pyren-1-yl)phenyl)phosphonic acid (PhPAPy).
  • Ab initio molecular dynamics (AIMD) simulations to study molecular orientation and packing.
  • Fabrication and testing of inverted PSCs using PhPAPy SAM.
  • Long-term stability testing under continuous illumination and elevated temperature.

Main Results:

  • PhPAPy forms a homogeneous and dense SAM layer due to its rigid structure and π-π interactions.
  • AIMD simulations show a near-vertical molecular orientation, minimizing perovskite-substrate contact.
  • Inverted PSCs with PhPAPy achieved a certified PCE of 26.74% and SPO of 26.12%.
  • Devices maintained 95% of initial efficiency after 2000 hours of stability testing.

Conclusions:

  • PhPAPy SAM effectively passivates the perovskite-substrate interface, reducing defects and enhancing performance.
  • The developed SAM significantly improves both the power conversion efficiency and operational stability of inverted PSCs.
  • This work offers a promising strategy for advancing high-performance and durable perovskite solar cell technology.
