PV manufacturers have improved solar panel output by 10W each year, while continuing to reduce manufacturing costs year-on-year. This “Efficiency Clock” is driving manufacturers to transition from conventional cells to more complicated architectures with superior materials properties. Advanced solar cells with greater than 20% efficiency require new equipment with precision materials engineering capabilities in doping, passivation and metallization, to enable key features such as passivated rear emitters, localized doping for contacts or selective emitters, and fully back contacted cells, while meeting cost/W targets. Our products and process integration know-how will simplify this transition to higher efficiency, advanced cell architectures.
