PatentCovers Natcore's Foundational Technology for Growing Thin FilmsNecessary in Solar Cells, Semiconductors, Fiber Optics and OtherApplications

RED BANK, N.J., May 10/PRNewswire-FirstCall/ -- The U.S. Patent Office has awarded a patentto Natcore Technology Inc. (TSX-V: NXT; Pink Sheets: NTCXF.PK) for itsproprietary Liquid Phase Deposition (LPD) process for growing films onsilicon.

Natcore'sLPD process makes it possible to grow a wide range of inorganicmaterials such as silicon dioxide-based films using a room-temperature,environmentally friendly chemical bath -- thereby eliminating the needfor harsh and expensive chemical vapor deposition (CVD) methodscurrently used in industry.

Thesesilicon dioxide films are essential elements of semiconductors,fiber-optic components and solar cells, among other important uses.Natcore's LPD process is expected to significantly lower manufacturingand environmental costs in many of these applications. The LPD processwill also allow for the development of advanced materials and devicesthat would otherwise be destroyed during the high-temperature CVDprocess currently being used by industry.

The basic patent has been assigned the number 7,718,550 and will be issued on May 18.This U.S. patent award provides Natcore with intellectual propertyprotection for its LPD invention in the world's largest and mostimportant market. Natcore's LPD process had already been granted patentprotection in Russia, and is currently in application in other major jurisdictions throughout the world.

"Thispatent for our signature LPD process strengthens Natcore's position asa leader in green technologies that are changing the way the worldproduces energy," said Chuck Provini,Natcore's president and CEO. "It is this foundational discovery thatallows us to grow revolutionary anti-reflective (AR) films for solarcells, and is the driving force behind our goal of creatingsuper-efficient tandem solar cells."

Brien Lundin,Natcore's chairman, notes that, "This technology holds tremendouspromise not only for solar energy production, but also opens up newfrontiers in semiconductors, optoelectronics, ophthalmology,environmental remediation and countless other exciting areas. It hasalways been our plan to explore and exploit these potentialapplications in due course."

As a result of its acquisition of NewCyte Technology in December 2009,Natcore holds three other U.S. patents -- one relating to film growthon fullerenes, a second concerning the creation of interfaces betweennanoparticles and biological molecules or systems, and a third that hasto do with the uses of silica-coated carbon nanotubes. A major areawhere this third patent can be used is for advanced low cost, highperformance fuel cells. Natcore is continuing to work on patentapplications for new technologies and applications being discovered anddeveloped through its research programs at Rice University and Ohio State University.
