Abstract
In this study, a temperature self-regulating solar reactor based on VO2 thermochromic coating is demonstrated. The temperature of solar reactor can be stabilized at 68.8 °C, which is corresponded to the critical point of metal-to-insulator transition of VO2. By employing the solar reactor, the orthorhombic phase CsPbI3 microwires have been synthesized through solution phase reaction route. Strong emission peaks at 490 nm and 470 nm have been observed in CsPbI3 microwires under ultraviolet and soft X-ray excitation, respectively. The high performance photodetector based on CsPbI3 microwire show a detectivity of 1.09 × 1014 Jones, responsivity of 4.72 A/W, rapid rise and decay time of 0.96 and 0.93 s at 325 nm. Our results demonstrate that the temperature self-regulating solar reactor can be applied for energy-saving solution phase reactor for synthesizing high quality inorganic materials.
