The efficient and comprehensive utilization of solar energy is of great significance for the sustainable development of energy and the realization of the strategic objectives of peak carbon dioxide emissions and carbon neutralization. Firstly, focus on the two main solar energy utilization modes, photovoltaic and photothermal, we systematically introduced the main types, research status and development trend of photovoltaic technologies, as well as the current situation and development trend of thermal power generation, building heating and refrigeration, seawater desalination and industrial heating in photothermal utilization. Then, we discussed the basic principles, main types and research progress of photovoltaic/thermal integration technology, especially the integration technology combined with the phase change heat transfer mode, was systematically introduced. Finally, several flexible "photovoltaic +" solar energy utilization technologies were introduced briefly. Photovoltaic, photothermal, photovoltaic/thermal integration and "photovoltaic +" technologies are still in a period of rapid development, have huge application potential and breed a large number of new technological growth points. These technologies are of great significance to solve the energy and environmental crisis and maintain the sustainable development of human society.
