Abstract

Provided is a method for producing a highly efficient organic/inorganic hybrid solar cell using fully aqueous phase-synthesized semiconductor nanocrystals and conducting polymer. The method mainly includes three steps: synthesizing nanocrystals in an aqueous phase, synthesizing a conjugated polymer precursor in an aqueous phase, and producing a device of solar cell. The nanocrystal material required for producing a solar cell by the method is widely available, diversified and size-controlled, and the used conjugated polymer has regulated molecular structure and molecular weight, which contributes to increase the absorption of sunlight. The processing of cell device can be performed at room temperature in air, and has advantages of no pollution, short processing period, and low cost. A method for producing an organic/inorganic hybrid solar cell is developed, which succeeds in introducing the high quality nanocrystals synthesized in an aqueous phase and is an eco-friendly and pollution-free technology for producing a solar cell.
