Photovoltaic nanocomposite comprising solution processed inorganic bulk nano-heterojunctions, solar cell and photodiode devices comprising the nanocomposite

Abstract

Photovoltaic nanocomposite and solar cell device including the photovoltaic nanocomposite, where the photovoltaic nanocomposite includes a film of solution processed semiconductor materials having an n-type material selected from n-type quantum dots and n-type nanocrystals, and a p-type material selected from p-type quantum dots and p-type nanocrystals, and where the n-type material has a conduction band level at least equal, compared to vacuum level, to that of the p-type material, the p-type material has a valence band at the most equal, compared to vacuum level, to that of the n-type material. at least a portion of the n-type material and at least a portion of the p-type material are present in a bulk nano-heterojunction binary nanocomposite layer having a blend of the n-type material and the p-type material.
