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