DuPont™ Innovalight™ Silicon Inks for Selective Emitter Solar Cells

DuPont Innovalight offers cell manufacturers easy-to-implement solutions to improve profitability

DuPont Innovalight provides innovative silicon inks and licenses proprietary high-efficiency solar cell process technology to solar cell manufacturers which enables an immediate increase in solar cell conversion efficiency for customers.

DuPont Innovalight’s selective emitter platform is the latest low cost cell design enabled by DuPont Innovalight silicon ink that allows cell manufacturers to quickly break through the efficiency ceiling.

The proprietary material is comprised of silicon nano-particles formulated into a screen printable ink. The result of over 100 engineering-years of ink development, DuPont Innovalight has optimized silicon ink powder and formulation properties to maximize the conversion efficiency of the DuPont Innovalight selective emitter platform. Additionally, the material was formulated to be compatible with low-cost industry standard screen printers – the same tool cell manufacturers use for printing metal contacts.

DuPont™ Innovalight™ continues to innovate and are working on an extensive roadmap for use of Silicon technologies and doping technologies to create advanced high efficiency solar architectures using standard industry tools and processes.

Low CostManufacturing cost on a per watt basis is lowered

Quick Path to High EfficiencyFast evaluation and quick ramp-up of production lines

RetrofittableExisting manufacturing lines can be retrofitted with Silicon Ink printing

Low RiskScreen printers are low cost, low risk equipment with a well established supply base and service infrastructure

Flexible Implementation In response to the strong demand for faster access and deployment of new technology for high efficiency cells and modules, DuPont has a new commercial offering for customers to implement selective emitter technology using the DuPont Innovalight selective emitter technology platform.

Flexible licensing terms to meet customers preference (by the factory, by the line, by the cell, by the kg)

Full/partial technology deployment by DuPont or customer self-deployment option
