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...

Peripheral and Non-Peripheral Substituted Phthalocyanines
This invention is directed to phthalocyanine chromophores with chalcogen based substituents on the peripheral and non-peripheral positions - phthalocyanine chromophores that have alkylthio (i.e., RS-) and alkoxy (i.e. RO-) on the peripheral (2,3,9,10,16,17,23,24) and nonperipheral (1,4,8,11,15,16,22,25) positions of the macrocyclic ring.

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...

Soluble Titanyl Phthalocyanines with Enhanced Thin-Film Near-IR Absorptivity
This patented technology covers materials and methods for making Titanyl Phthalocyanines (TiOPc) and rendering them soluble using peripheral substituents. In addition, the method eliminates the need for a solvent in the synthesis step, and increases the purity of yield of the isolated materials. Furthermore, the organic molecules exhibit increased absorbance...
