Chen et al. developed a comprehensive solar resource assessment system based on the GIS + MCDM method in 2019. This system was applied to the assessment of the potential of PV power generation in the countries under the “Belt and Road” initiative. The results showed that the PV potential of China is 100.8 PWh.
In 2009, the production capacity of PV panels in China nearly reached 4000 MW; a remarkable increase compared with only 5.5 MW of output in 1997 . China is now the largest manufacturer of solar PV products in the world . In addition, the government is investing heavily into this field for relevant scientific research.
On the basis of analysis of the four factors that impact the development of China’s PV power generation, including solar-energy resources in China, PV industry conditions, research and development of solar-cell technology, and related PV policies, the prospects and development potential of PV power generation in China are discussed.
Fig. 2. Spatial distribution of annual theoretical power generation of China in 2015. The results of theoretical PV power generation show that the high-value areas are mainly concentrated in the Qinghai-Tibet Plateau, followed by Northwest China and Yunnan, where are rich in solar radiation resources.
The PV power generation potential of China was estimated using ERA5-Land hourly data with a spatial resolution of 0.1° × 0.1° (about 10 km × 10 km), and a temporal resolution of 1 h. The quality of the data of ERA5 has also been improved compared to the previous data .
So far, many studies have been conducted on solar PV developments in China, yet the majority of these focused on the top-down dimension, which is central government policy guidance, whereas the bottom-up dimension in the policy-making process, that is, the influence of PV enterprises and local governments on the central government, is overlooked.

The Working Principle of a Solar Cell
The working principle of solar cells is based on the photovoltaic effect, i.e. the generation of a potential difference at the junction of two different materials in response to electromag-netic radiation. The photovoltaic effect is closely related to the photoelectric effect, where electrons are emitted from a material that has absorbed light with a frequency above a material-dependent ...
