A PN junction is simply the boundary formed when a P-type and an N-type semiconductor are joined together, creating a depletion region and a built-in electric field that separates charges. This internal electric field is what makes solar cells generate electricity. The cell's function relies on a. The magic happens when you bring some n-type material next to some p-type material, and create what's called a p-n junction.

This study reviews research publications on rooftop photovoltaic systems from building to city scale.
Photovoltaic panel installations in roofs with different formats. PV modules can be placed horizontally or at an angle on flat roofs (Bayod-Rujula et al., 2011). In sloped roofs, PV modules are generally applied at the same inclination angle as the roof, and placed in parallel to increase the system efficiency.
The roof with a PV panel delivers 16% more energy than the system without tracking. The use of building-integrated photovoltaic (PV) systems in the form of retractable roofs is an alternative option to existing installations without tracking systems (NT) or horizontal single-axis tracking systems (HSAT).
The unique properties of roofs, such as good sunlight incidence, good ventilation conditions, no redundant shielding, and flexible tilt angle for PV panels, are advantageous for solar energy harvesting. Accordingly, roofs present the highest efficiency potential for PV generation systems in buildings (Lin et al., 2014).

Gernaat et al. (2020) estimated that the global suitable roof area for PV generation was 36 billion square meters. This represents a potential of 8.3 PWh/y, which is equivalent to 150% of the global residential electricity demand in 2015. This demonstrates the potential of replacing traditional electricity sources with rooftop PVs.
