30% More Power, 20% Lower Costs: Scott Graybeal on Solar’s Step-Change Moment

Hardware to Save a Planet · 5 Mar 2026 · 52m · Episode 97

What this episode covers

Scott Graybeal, CEO of Caelux, explains how the company is commercializing perovskite solar technology by depositing a thin 'active glass' layer onto conventional silicon modules to achieve 30–40% higher power output. He details the tandem cell architecture that splits the light spectrum to improve efficiency, the company's manufacturing roadmap scaling to 100 MW, and the strategic decision to partner with incumbent module manufacturers rather than building a full module factory. Graybeal also discusses the economic impact of lower levelized cost of energy, the shift away from China-centric manufacturing due to lower capital requirements, and the future potential of flexible, printed solar applications.

    An Interview with Sam Stranks

    Chris Gammell, a physicist at Cambridge University and co-founder of Swift Solar, explains the rapid efficiency gains in perovskite solar cells, which have jumped from 3% to over 24% in just a few years. He details the material's unique defect tolerance, low-temperature solution processing, and potential for lightweight, printed tandem cells that could drastically reduce installation costs. Gammell also discusses non-solar applications like LEDs and lasers, while noting that ion migration remains a key stability challenge for commercial viability.

    Scaling America's domestic solar supply chain

    Scott Moskowitz, VP of market strategy and public affairs at QCells and chair of the Solar Energy Industries Association (SEIA), discusses the challenges and progress of reshoring solar manufacturing to the United States. He explains that while module assembly and polysilicon production have been domesticated, the critical middle stages of wafer and cell manufacturing are only just beginning to scale, with companies like QCells and Hemlock Corning leading the charge. Moskowitz highlights that despite US modules costing roughly 30 cents per watt compared to 7-9 cents globally, high demand driven by data centers and AI load growth has made domestic production economically viable, though achieving global cost competitiveness remains a long-term goal requiring scale and policy continuity.

    82. 3D Printing Space Sensors & Solar Cell Windows

    Hosts Farbod and Daniel discuss MIT's use of 3D printing with Vitrolite ceramic to manufacture low-cost Retarding Potential Analyzer (RPA) sensors for CubeSats, and the University of Michigan's development of semi-transparent organic solar cells for windows. They detail how digital light processing enables precise electrode housing fabrication, reducing costs from thousands to under $100, while a masking tape-like process allows scalable production of organic solar modules with 7.3% efficiency. The episode highlights the democratization of space sensor technology and the near-future commercialization of solar windows and OLED lighting.

    Solar Cells, SparkFun, TSMC - The Detroit Debunking

    Chris Gammell and Dave Jones discuss SparkFun's new 'pick and place grab bag' program, which sells rejected components from automated assembly lines for $10, noting the trade-off between cost and the time required to sort and test them. They analyze TSMC's announcement of a $500M solar cell manufacturing plant in Mississippi, debating whether low US labor costs and local incentives create a viable inflection point for reshoring manufacturing compared to China. The hosts also critique IEEE's membership fee structure for unemployed engineers, the reliability issues of Compact Fluorescent Lamps (CFLs), and the growing problem of electronic waste recycling overseas.
