Abstract: Disclosed herein are a recombination layer containing nanoparticles and an integrated tandem solar cell manufactured using the same. The integrated tandem solar cell includes a first solar cell having a form in which a rear electrode, a light absorption layer, and a buffer layer are stacked, a recombination layer formed on the buffer layer and including a triple layer structure which has first and second transparent conductive layers with a transparent conductive nanoparticle layer disposed therebetween, and a second solar cell disposed on and bonded to the recombination layer and including a perovskite layer.
