PLEXIGLAS® Solar Pre-Fab Optics – the complete acrylic lens package for CPV

  • High efficiency combined with time and cost savings for customers 

Evonik offers a complete acrylic lens package, PLEXIGLAS® Solar Pre-Fab Optics, designed to provide access to Concentrated Photovoltaic (CPV) optics, while also saving customers significant costs and lead times associated with tooling. These lens panels are part of the well-known PLEXIGLAS® Solar (ACRYLITE® Solar in the Americas) product portfolio, which consists of specialty PMMA molding compounds and sheet products for solar applications.

PLEXIGLAS® Solar Pre-Fab acrylic lens panels are combined with a Secondary Optical Element (SOE) to create a complete optical train package for assembly directly into Concentrated Photovoltaics (CPV) modules. This allows customers to forgo the purchase of a tooling device needed to create the product, which is very expensive and requires a time-consuming installation process of several months.

“This is a great example of how we continuously enhance our products to deliver our best value and performance to our customers,” said Christopher Walby, new business development manager of Evonik’s Acrylic Polymers business line. “The package’s complete offering allows us to deliver world-class performance to our customers while bypassing the tooling process to save both time and money. We are also offering the product in small quantities of as little as 10 panels to be used in prototypes.”

The optical lens package utilizes Light Prescriptions Innovators’ (LPI) patented Fresnel-Köhler optical design.
The PLEXIGLAS® Solar Pre-Fab lens panel serves as the Primary Optical Element (POE), which collects light over its entire area. This POE is coupled with the Secondary Optical Element (SOE), which focuses and homogenizes light over a smaller area in order to maximize its usefulness to a solar cell. SOEs designed for use in conjunction with the PLEXIGLAS® Solar Pre-Fab lens panel include Light Prescriptions Innovators’ (LPI) glass SOE and Evonik’s SAVOSIL® Secondary Optical Element. Optical Services and system integration support are also available through LPI.

PLEXIGLAS® Solar Pre-Fab Optics are produced through Evonik’s proprietary processes for manufacturing acrylic CPV lens panels. These lens panels also take advantage of the precision tooling and prescription replication capabilities of 10x Technology LLC, a developer of micro-structured polymer products. Furthermore, PLEXIGLAS® Solar Pre-Fab lens panels provide excellent light transmission, high mechanical strength, low weight and outstanding resistance to weathering and UV light.

PLEXIGLAS® Solar Pre-Fab Optics are available in three different quantities - 10 panels, 50 panels, and 100 panels.

Evonik Industries is a worldwide manufacturer of PMMA products sold under the PLEXIGLAS® trademark on the European, Asian, African and Australian continents and under the trademark ACRYLITE® in the Americas.
