Abstract: A solar cell includes a first electrode, a second electrode spaced apart from the first electrode, and a light absorption layer between the first electrode and the second electrode. The light absorption layer includes a first absorption sublayer, a second absorption sublayer and a third absorption sublayer. The first absorption sublayer contacts the first electrode and includes a first quantum dot, the second absorption sublayer is between the first absorption sublayer and the third absorption sublayer and includes a second quantum dot, and the third absorption sublayer contacts the second electrode and includes a third quantum dot. The second quantum dot is larger than the first quantum dot and the third quantum dot.
