What is photovoltaic (PV) power generation?
Photovoltaic (PV) power generation is the main method in the utilization of solar energy, which uses solar cells (SCs) to directly convert solar energy into power through the PV effect.
Why is a photovoltaic module tilted?
In addition, photovoltaic (PV) module is usually tilted to capture the most of the solar radiation available at a given location [14, 15, 16]. The knowledge of the solar radiation on the horizontal surface and the optimal tilt angle for any given location can greatly help in the design of solar power with enhanced energy yield.

What is the maximum efficiency of a solar cell?
Well, the maximum efficiency of a commercially available solar cell recorded to date has been 33.7%. This has been one of the biggest challenges to the Solar industry, but why are there such limitations to the efficiency of a solar panel? We'll get to that answer shortly, but first, it's important for us to understand what exactly a solar cell is.
