Advent Solar Introduces Ventura(TM) Technology to Accelerate Scalable Silicon Photovoltaic Solutions
VALENCIA, Spain, Sept. 1 /PRNewswire/ -- European Union Photovoltaic Solar
Energy Conference -- Advent Solar, Inc., a manufacturer of innovative solar
cells and modules, today announced the solar industry's first cell-to-module
solar architecture -- Advent Solar(R) Ventura(TM) Technology. Ventura Solar
Technology provides a platform-level design by combining Emitter-Wrap Through
(EWT) back-contact cells with semiconductor device manufacturing methods to
create a highly scalable platform for module manufacturing. With Ventura
Technology, Advent Solar will develop solar cells and modules that deliver
high energy output by optimizing silicon light capture, and dramatically
improving cell and module-level connectivity to minimize resistive losses. The
architecture provides higher cell-to-module efficiency, while using thinner
silicon wafers to reduce costs. The company also launched a new logo and brand
strategy to convey its new business and technology direction.
"Conventional photovoltaic manufacturing has nearly exhausted its
resources in improving efficiency, cost and reliability, and creative design
and technology approaches are needed to make photovoltaic-based solutions a
viable and reliable energy alternative," said Peter Green, president and CEO
of Advent Solar. "Advent Solar Ventura Technology breaks through efficiency
bottlenecks inherent in conventional methods and powers the way to a new
generation of photovoltaic products that rapidly move the industry closer to
grid parity. It marries innovative solar cell and module technology with
semiconductor manufacturing techniques, which results in highly-efficient
solutions that can be produced and installed in volume."
Ventura Technology architecture features:
-- Emitter Wrap-Through (EWT): By eliminating the front grid, more
sunlight becomes available for electrical conversion. EWT provides higher
light capture and efficient distribution of energy to the backside contacts.
The Ventura architecture combines the EWT back contact cell design with MMA to
deliver a scalable, high output module platform.
-- Monolithic Module Assembly (MMA): This enables fully automated module
assembly, applying proven, high volume, high precision semiconductor-style
manufacturing techniques. Using robotic "pick and place" methods, each cell is
perfectly arranged onto a monolithic integrated circuit backsheet. Novel
bonding techniques form low resistance electrical contacts between the cells
and monolithic circuit. By reducing the complexity of manufacturing processes,
this approach results in highly repeatable, consistent module output with
maximum yields.
-- Reduced Silicon Thickness: The Ventura Technology approach minimizes
the handling of cells during the manufacturing process. The fully automated,
soft-handling manufacturing flow can accommodate silicon wafers that are much
thinner than conventional assembly methods, providing scalability for silicon
cost reductions and higher yields.
-- Superior Bonding: Ventura Technology utilizes multiple contact areas
with bonds strategically distributed across the cell to disperse stress
throughout the entire backside of the cell. In addition to improved electrical
performance, this provides higher levels of quality and reliability at the
module level.
-- Beautiful by Design(TM) Products: Ventura Technology products are
designed to be aesthetically pleasing. Designed with building integrated
photovoltaic (BIPV) market needs in mind, they feature perfectly aligned,
clean, blue silicon squares that customers are proud to showcase.
To benchmark significant strides in the advancement of solar photovoltaic
solutions, Advent Solar is also unveiling the Solar Green Index. The index
measures the efficiency and value of silicon-based photovoltaic architectures
from a systems perspective. Key index factors include the ratio of module
efficiency to cell efficiency, and a manufacturing precision factor -- the
higher the index, the better the value delivered.
Advent Solar will provide additional information regarding Ventura
Technology at booth 4/C 12 during the European Union Photovoltaic Solar Energy
Conference.
