Bell Works is the product of the successful revitalization of the two-million-square-foot Bell Laboratories in Holmdel, NJ. The mixed-use ‘metroburb’ is now a popular destination to work, shop, dine and more. All the works carried out in the remodeling of the building were intended to preserve its original features. Onyx Solar has supplied Bell Works with amorphous silicon photovoltaic glass panes, covering a total area of 60,000 sq ft, to create the largest photovoltaic skylight in the USA.


These glass modules installed on the skylight provide this multipurpose building with a lot of natural illumination by capturing daylight and are also able to produce electricity free of CO2  emissions. It reduces the carbon footprint by preventing the emission into the atmosphere of approximately 60 tons of CO2 yearly. The building produces the necessary energy to drive 100 electric cars 4,250 miles per year.


The skylight features 24 different types of glass modules which are used in the different sections of the Eero Saarinen-designed building, being all of them produced using cutting-edge technology at our factory. Each one of the modules is made of amorphous silicon thin film photovoltaic (a-Si PV) active glass, which is placed between two sheets of tempered safety glass. The modules transmit 20% of Visual light (VLT) so that they can reduce the heating of the panes while they produce electricity.

This building, which was constructed between 1959 and 1982, has served as the home to over 6,000 engineers and researchers. The facility as well as its layout are studied in universities as models of modernist architecture. Researchers of this complex have the credit of having developed and invented radio astronomy, the transistor, the laser, the photovoltaic cell, the Unix operating system, and programming languages such as C. Nine Nobel Prizes have been awarded for works completed at Bell Laboratories.


Somerset Development purchased this complex in 2013 and the facility underwent further reconditioning to include new services. Onyx Solar participated by installing the glass panes on the skylight in this latest remodelling.


At Onyx Solar we feel that we are giving back to a building that has witnessed the discovery of so many innovations, including the solar cell. Ralph and his team are taking on a great mission with Bell Works; congratulations on the efforts”.

Diego Cuevas, Onyx’s VP Business Development.

“Bell Works is already home to an extraordinary community of innovators, and it’s our job to continue to innovate the building commensurately. People want a workplace that extends itself beyond professional needs one that stands for something beyond the cubicle walls. As Bell Works continues to attract some of the region’s most forward-thinking companies, it is only fitting that it incorporates the latest in sustainable technology, all in a way that is both functional and attractive”.

Ralph Zucker, President of Somerset Development of Bell Works
