# 1366 Technologies: High-Level Overview
1366 Technologies is a silicon wafer manufacturer that pioneered a revolutionary manufacturing process to dramatically reduce the cost and environmental impact of solar panel production.[1][3] Founded in 2007 and based in Bedford, Massachusetts, the company developed the Direct Wafer® process, which produces silicon wafers directly from molten silicon rather than sawing them from large ingots—a manufacturing method that had remained largely unchanged for over 50 years.[3][4]
The company serves solar cell and module manufacturers by providing high-performance silicon wafers that enable significant reductions in the levelized cost of energy (LCOE).[5] By eliminating the traditional ingot-cutting approach, 1366's technology reduces manufacturing steps from four to one, cuts energy consumption substantially, and eliminates wasteful silicon byproduct known as "kerf."[3] In June 2021, 1366 Technologies merged with Hunt Perovskite Technologies to form CubicPV, combining Direct Wafer technology with perovskite solar photovoltaic technology to develop next-generation tandem solar modules.[5]
# Origin Story
1366 Technologies was founded in 2007 with a mission to reinvent solar wafer manufacturing.[1] The company's name references the solar constant—1,366 watts of solar energy hitting each square meter outside Earth's atmosphere.[4]
A pivotal moment came in December 2009 when 1366 secured a $4 million grant from the U.S. Department of Energy's Advanced Research Projects Agency-Energy (ARPA-E) to fund research over an 18-month period.[4] Just eight months into the grant period, the company achieved a critical breakthrough: successfully casting molten silicon directly into molds to produce finished wafers measuring 6 inches square and 200 micrometers thick.[4] This proof-of-concept validated the core technology and positioned the company as a serious contender in solar innovation.
The company raised $281.42 million in total funding and progressed through multiple generations of manufacturing equipment, eventually planning a commercial-scale factory in upstate New York slated for completion in 2017, designed to produce 50 million wafers annually (250 megawatts of output), scaling to 600 million wafers and 3,000 MW annually.[1][4]
# Core Differentiators
- Proprietary casting process: The Direct Wafer® technology produces wafers directly from molten silicon in a single step, eliminating the multi-step ingot-cutting method that has dominated the industry for decades.[3][4]
- Dramatic cost reduction: Management projected the technology could produce wafers at half the cost of current methods, with ARPA-E targeting a reduction in solar electricity costs from $0.15 to less than $0.07 per kilowatt hour by 2020.[4][7]
- Environmental advantages: By eliminating kerf waste and reducing energy consumption, the process drastically lowers the carbon footprint of solar panels.[3]
- Continuous flow manufacturing: Unlike traditional ingot production requiring massive crucibles kept hot for days, 1366's approach uses a small crucible continuously replenished, enabling consistent uninterrupted production.[3]
- Industry recognition: The company has been recognized as a finalist for the Zayed Future Energy Prize, a Fast Company Most Innovative in Energy honoree, a Bloomberg New Energy Pioneer, and one of MIT Technology Review's "50 Smartest Companies in the World."[3]
# Role in the Broader Tech Landscape
1366 Technologies sits at the intersection of two critical trends: the global race to achieve terawatt-scale solar deployment and the push to reduce solar's levelized cost of energy to compete with fossil fuels.[2][5] The company's innovation addresses a fundamental bottleneck in solar manufacturing—a process that had stagnated for over half a century.
The timing of 1366's emergence proved crucial. As solar adoption accelerated in the 2010s, the industry faced mounting pressure to reduce costs while scaling production. Traditional wafer manufacturing, with its inherent waste and multi-step complexity, became an increasingly obvious target for disruption. By combining Direct Wafer technology with perovskite solar cells through the CubicPV merger, 1366 positioned itself to influence the next generation of solar technology—tandem modules that promise significantly higher efficiencies than conventional silicon-only cells.[5][6]
The company's influence extends beyond its own products: by demonstrating that fundamental manufacturing innovations remain possible in mature industries, 1366 has helped legitimize deep-tech approaches to climate solutions and influenced how venture capital and government agencies (like ARPA-E) evaluate energy technology investments.
# Quick Take & Future Outlook
1366 Technologies exemplifies the potential of manufacturing innovation to reshape energy economics. The company's merger with Hunt Perovskite Technologies signals a strategic pivot toward tandem solar modules—a technology that could deliver step-function improvements in solar efficiency and economics.[5][6]
Looking forward, the critical question is execution: whether CubicPV can scale Direct Wafer production to the volumes and cost targets originally envisioned while simultaneously integrating perovskite technology into commercially viable modules. Success would position the combined entity as a foundational supplier to the solar industry during its transition to terawatt-scale deployment. The convergence of manufacturing innovation, favorable policy tailwinds, and the urgent need for cost-competitive renewable energy creates a compelling backdrop for the company's next chapter—one that could validate the thesis that century-old manufacturing processes can still be fundamentally reimagined.
