PLEXIGLAS® Solar Pre-Fab Optics – high efficiency combined with time and cost savings for customers

  • Newly Available Off-the-Shelf Optical Train Is First For CPV Modules

Darmstadt, Germany – Evonik is launching a complete acrylic lens package, PLEXIGLAS® Solar Pre-Fab lens panels, designed to provide access to Concentrated Photovoltaic (CPV) optics while also saving customers costs in advance and several months manufacturing time. These new lens panels are part of the well-known PLEXIGLAS® Solar 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 bypass buying the 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 Peter Marks, new business development manager of Evonik’s Performance Polymers – 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 panels serves as the Primary Optical Element (POE), which collects light over its entire area. This POE is coupled with Evonik’s SAVOSIL®, the Secondary Optical Element (SOE) that focuses light over a smaller area homogenizing the light in order to maximize its usefulness to a solar cell.

The PLEXIGLAS® Solar Pre-Fab lens panels 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 capability 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 and low weight as well as outstanding resistance to weathering and UV light.

PLEXIGLAS® Solar Pre-Fab is offered in three sets of quantities -- 10 panels, 50 panels, and 300 panels -- and will be launched at the CPV-8 conference in Toledo, Spain, on April 16th.

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.
