Organic photosensitive devices with exciton-blocking charge carrier filters

Title: Organic photosensitive devices with exciton-blocking charge carrier filters

Disclosed herein are organic photosensitive devices including at least one exciton-blocking charge carrier filter. The filters comprise a mixture of at least one wide energy gap material and at least one electron or hole conducting material. As described herein, the novel filters simultaneously block excitons and conduct the desired charge carrier (electrons or holes).

Organic photosensitive cells having a reciprocal-carrier exciton blocking layer

Patent Rand, Barry P ; Forrest, Stephen R ; Thompson, Mark E

A photosensitive cell includes an anode and a cathode; a donor-type organic material and an acceptor-type organic material forming a donor-acceptor junction connected between the anode and the cathode; and an exciton blocking layer connected between the acceptor-type organic material of the donor-acceptor junction and the cathode, the blocking layer consisting essentially of a material that has a hole mobility of at least 10.sup.-7 cm.sup.2/V-sec or higher, where a HOMO of the blocking layer is higher than or equal to a HOMO of the acceptor-type material.

Organic photovoltaic cell incorporating electron conducting exciton blocking layers

Patent Forrest, Stephen R. ; Lassiter, Brian E.

The present disclosure relates to photosensitive optoelectronic devices including a compound blocking layer located between an acceptor material and a cathode, the compound blocking layer including: at least one electron conducting material, and at least one wide-gap electron conducting exciton blocking layer. For example, 3,4,9,10 perylenetetracarboxylic bisbenzimidazole (PTCBI) and 1,4,5,8-napthalene-tetracarboxylic-dianhydride (NTCDA) function as electron conducting and exciton blocking layers when interposed between the acceptor layer and cathode. Both materials serve as efficient electron conductors, leading to a fill factor as high as 0.70. By using an NTCDA/PTCBI compound blocking layer structure increased power conversion efficiency is achieved, compared to anmore »« less
