Photo voltaic Innovations has patented expertise that may save between $2 million and $5 million per gigawatt on photo voltaic initiatives, whereas additionally rising rated energy output. The corporate holds patents in the US, China and Israel for its cell configuration.

US-based Photo voltaic Innovations has revealed that it has obtained patents in the US, China and Israel for a novel structure for PV cells and modules.
Ben Damiani, chief expertise officer of Atlanta-based Photo voltaic Innovations, says a producer can create a number of “lanes” or subcells on a wafer by dividing every cell’s electrical energy throughout metallization course of. The Configurable Present Cells (C3) course of doesn’t require any capital expenditure or course of modifications to be applied by photo voltaic cell producers. For cell producers, C3 requires solely minor modifications in metallization print patterns and selective doping.
The method creates a brand new structure that makes enhancements in cell, module, and system efficiency whereas saving as much as 18% of the silver required. This equates to $2 million to $5 million in financial savings per gigawatt beneath present silver costs, as silver sometimes represents about 10% of a photo voltaic module’s value construction. Choose pilot exams and modeling additionally present as much as 3 W per panel of extra energy.
US authorities have lately issued a continuation patent that expands the claims from the primary Photo voltaic Innovations patent and consists of configurations for many trendy cell constructions.
“Because the photo voltaic trade transitions to new cell constructions similar to Topcon and HJT and manufacturing continues to speed up worldwide, the financial advantages of our Configurable Present Cell (C3) expertise are gaining significance,” mentioned mentioned Damiani. “C3 dramatically will increase silver value financial savings for photo voltaic cell producers, whereas rising energy and sturdiness.”
In September 2019, the expertise gained first place within the US Division of Power’s American-Made Photo voltaic Prize contest for brand spanking new applied sciences.
C3 cells are primarily based on Damiani’s Resistively Sure Subcells (RBS). C3 creates remoted modifications in cell resistance via a mix of laydown modifications in metallization. The patent identifies particular metallization patterns, each on high and backside of the cells, that collectively create exact areas of excessive cell resistance. These are used as electrical boundaries round hybrid subcells. These subcells exhibit traits that have been beforehand solely potential with unique wafer processing methods or bodily cleaving similar to half-cells, mentioned Photo voltaic Innovations.
