With the continuous expansion of the photovoltaic solar energy industry worldwide, its application mode is becoming more diversified, and there have been progress in many aspects such as "photovoltaic + energy storage", "photovoltaic + agriculture", and "photovoltaic + construction". In terms of photovoltaic-energy storage, the continuous development of energy storage technology can further promote the application of new energy, and at the same time it will make the applicability of photovoltaic power generation more diversified. In terms of photovoltaic-agriculture, more and more regions are exploring the development path of agro-photovoltaic complementary mode. In terms of photovoltaic-construction, the combined use of photovoltaic and construction has been widely recognized for its role in promoting the improvement of building energy efficiency and reducing building operating energy consumption. In addition, there are certain developments in many "photovoltaic +" fields such as photovoltaic-communication, photovoltaic-ecological governance, photovoltaic-transportation, etc. The diversified expansion of photovoltaic applications will further broaden the future photovoltaic market scale.

As a renewable clean energy source with easy access and high cost performance at present, solar photovoltaic bears the responsibility of carbon neutrality in the era of carbon neutrality, and becomes the main energy source. According to IRENA's prediction, the growth space will reach 16.5 times by 2050 compared with 2021, with high growth certainty.
