This paper reviews the transformative shifts within China’s photovoltaic (PV) industry against the backdrop of a global pivot from fossil fuels to renewable energies, a transition underscored by the pressing demands of climate change mitigation. By systematically analyzing existing literature, this study captures the rapid advancements and dominant role of China in the global PV market, spurred by robust governmental support and technological innovation. It also identifies persistent challenges such as technological gaps, supply chain instability, and evolving regulatory frameworks. Key findings highlight the industry’s significant contributions to national energy security and its pivotal role in achieving China’s carbon neutrality goals. This research underscores the critical importance of the PV industry in steering global sustainable energy policies and practices.
