P-N junction01:11

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...

Summary

Introducing [6,6]-phenyl-C(61)-butyric acid methyl ester (PCBM) as a hole-blocking layer significantly boosts hybrid thin-film solar cell efficiency. This enhancement stems from improved interfacial contact, reduced carrier recombination, and a record 8.34% power conversion efficiency.
