Filed:

Mar 5, 2010

Appl. No.:

13/254929

Inventors:

Lei Qian - Gainesville FL, US
Jihua Yang - Minneapolis MN, US
Jiangeng Xue - Gainesville FL, US
Paul H. Holloway - Gainesville FL, US

Assignee:

University of Florida Research Foundation, Inc. - Gainesville FL

International Classification:

H01L 31/0224
C01G 9/02
B82Y 40/00
B82Y 30/00

US Classification:

136256, 423622, 977896, 977773, 977948

Abstract:

A solar cell includes a low work function cathode, an active layer of an organic-inorganic nanoparticle composite, a ZnO nanoparticle layer situated between and physically contacting the cathode and active layers; and a transparent high work function anode that is a bilayer electrode. The inclusion of the ZnO nanoparticle layer results in a solar cell displaying a conversion efficiency increase and reduces the device degradation rate. Embodiments of the invention are directed to novel ZnO nanoparticles that are advantageous for use as the ZnO nanoparticle layers of the novel solar cells and a method to prepare the ZnO nanoparticles.
