  • Highly emissive short wave infrared nanoparticles and method for preparing the same
    Patent number: 11613700
    Abstract: The present invention provides shortwave infrared ray emitting nanoparticles including a core having band gap energy of E1; an intermediate layer that is formed on the core and has band gap energy of E2; and an outer layer that is formed on the intermediate layer and has band gap energy of E3, in which the size of the E2 is smaller than the size of the E1 and the size of the E3. According to the present invention, it is possible to provide a solar cell which is improved in efficiency and life span and can be produced by a solution process.
