The sun not only breeds all life, but also brings inexhaustible clean energy to the earth. The development of flexible photovoltaic technology, represented by flexible perovskite solar cells, frees the energy production from the constraints of traditional centralized photovoltaic application scenarios. From spacecraft and curved photovoltaics to wearable devices and IoT sensors, the combination of flexible photovoltaics and advanced technology will realize a more flexible, convenient and imaginative collection and utilization of solar energy, contributing to a more intelligent and sustainable human society.
