Organic Solar Cells Based on a Solution Phase Near-IR Absorbing Soluble Phthalocyanines
This invention is a solution-processed planar heterojunction (PHJ) organic photovoltaic (OPV) device based on a soluble titanyl phthalocyanine (TiOPc) derivative as the donor with photo activity extended up to 1 micron in the near-IR region of the solar spectrum, without significantly affecting the open-circuit photopotential (Voc). TiOPc is a metallated...

Solution Processed Bulk Heterojunction Organic Solar Cells Based on Near-IR Absorbing Soluble Phthalocyanines
This invention demonstrates excellent near-IR photoactivity for solution-processed Bulk Heterojunction (BHJ) OPV device. For the optimized BHJ devices, the VOC is (a) higher than the corresponding solution processed Planar heterojunction (PHJ) device fabricated from octahexylthio-substituted C6-TiOPc and (b) comparable to the vacuum-deposited PHJ fabricated...
