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...

Main Results:

Multi-type Si particle layers significantly enhanced absorbance compared to bare Si wafers.
Broadband absorbance boost observed within the wafer region, minimizing parasitic absorption.
Up to 40% improvement in short-circuit current and 30% in integrated absorbance with Si disk layers (four radii).
Metal multi-type layers showed limited broadband enhancement due to parasitic absorption.

Conclusions:

Regular particle arrays, particularly multi-type Si disk layers, are promising for enhancing photovoltaic device efficiency.
Careful design of particle geometry and material is crucial to avoid parasitic absorption and achieve broadband enhancement.
Further optimization without anti-reflection coatings shows substantial potential for photovoltaic applications.
