Abstract:

Self-aggregation of self-assembled monolayers (SAMs) in inverted organic-inorganic hybrid perovskite solar cells induces the formation of inhomogeneous and non-compact films, that cause energy loss in the devices. Thiourea modulates the uniform distribution of the SAM layer and optimizes the morphology of the buried interface. The treated perovskite solar cells achieved a maximum PCE of 25.15% and retained 91.2% PCE after 1200 hours of storage.

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...
