ClearVue PV’s executive chairman Victor Rosenberg first considered working in the building integrated photovoltaic (BIPV) space a few years after the company was formed in 1995, when it operated under its former name Tropiglas Technologies. The company’s core product offering is at its simplest highly energy efficient, ultra clear glass that generates electricity via solar technology. After working with organic materials within its prototype product, the company endured a number of setbacks before changing direction to focus on progressing a new advanced glazing solution. Fast forward to 2018 and after many years of refining its technology, ClearVue is close to officially launching a smart building material product that could disrupt some of the world’s biggest industries.

The interlayer contains inorganic nanoparticles, which fortifies the product and also converts ultraviolet (UV) light to the lower infrared range. “We keep the heat out and allow the visible light to go through. We then direct the infrared towards the edges by various mechanisms,” says Rosenberg. The reflected light is collected by photovoltaic cells at the edges of the glass, which currently produces 30W of energy per square metre of material, however the company expects to improve this to 50W per square metre with further research and development effort. In fact, the company has recently announced a significant new development to its technology, in that the solar cells can now be built into the entire structure, instead of just at the edges of the glass. This effectively widens the range of uses into additional markets and represents a key breakthrough for ClearVue’s technical team. “The whole product and technology is contained within a glass structure as an Integrated Glass Unit (IGU), so that you can’t actually get to the solar cells or the mechanisms inside the glass panel,” says

The answer lies in the fact that the technology is completely transparent and therefore doesn’t compromise aesthetics, while the solar glass is also product integrated and building integrated. Rosenberg believes there is no standard for both as of yet but hopes to change this once the certification process is completed. “We are hopefully going to be the first person to do both, in terms of it being a building material and a building product. It’s a glass structure, like normal glass except it has activity within the product.

RENEWABLE ENERGY | ClearVue PV Last year, the Federal Government of Australia granted ClearVue $1.6 million to build this world-first greenhouse that incorporates the company’s high-tech product. “They see the advantages like we do and it’s not easy to get money from governments, but they see that there is a clear advantage here. “In fact, wherever you go around the world, the biggest issue is food security,” Rosenberg continues. Already the company has received lots of interest from many areas of the world, all of which are looking for food security. ClearVue is working with industry partners and horticultural scientists to deliver the energy efficient greenhouse, which has recently passed the stage of preliminary drawings for the pilot project. “The reason that we want to work with these industry and scientific partners is because the outcomes need to be from an independent third party, not from us. The independent third party needs to publish the results and confirm what we are claiming.” Corroboration of a demonstration project from a reputable third party source is important for ClearVue as this essentially acts as the company’s salesman and is a key point of promotion for its product around the world. Furthermore, the company is planning to build several other live units in the coming months, including things such as bus shelters
