Review of Photovoltaic Cell Technology Development

China has pledged to peak its carbon footprint by 2030 and become carbon neutral by 2060. According to the future energy demand and the requirement to achieve “carbon neutrality”, the new energy represented by photovoltaic power generation will become the main force to achieve “carbon neutrality”. It is great strategic significant to increase the proportion of non-carbon energy gradually and build a new energy supply system with multiple complementary energy. According to the current situation of domestic energy development in recent years and the development trend of new energy in China, the author reviewed the development of photovoltaic cells technology. As the head industry of photovoltaic industry, photovoltaic cells were applied in multy prospects, such as agriculture and public transportation. Two feasible solutions toward the disadvantage of photovoltaic cell were discussed, including the appropriate geographical location of photovoltaic cells and the superhydrophobic coating on the surface of the cell.
