--To prevent global warming and energy depletion, it is imperative to develop renewable energy. Among various renewable energy sources, solar power has become the fastest-growing one due to its significant advantages of being clean, safe, and inexhaustible. The development and utilization of solar energy are of great significance for adjusting the energy structure, advancing the revolution in energy production and consumption, and promoting the construction of an ecological civilization.

According to data from the International Renewable Energy Agency (IRENA), the global cumulative installed capacity of photovoltaic power maintained a steady upward trend from 2011 to 2018, reaching 480,619.1 MW in 2018, a 25.0% increase from 2017. It is expected to continue its growth trend in the foreseeable future.
