Brite Solar was founded in 2009 to develop a third generation Dye Sensitized Solar Cell for greenhouse applications.
The resulting technology features such creative advances as ink-jet deposition of semiconductor material and a solid state electrolyte. This results in a Solar Glass which is >70% transparent in the visible spectrum, 3-4 times more thermally insulating than dual pane windows, electricity generating and cost effective.
Crop studies growing hydroponic tomatoes have shown that the crop yields are equivalent and the nutritional value slightly higher for tomatoes grown under the Brite Solar Glass as opposed to the normal glass.
Brite also has developed variations on the Solar Glass technology. The first is a low cost, thermally insulating Electrochromic Glass called Dynamic Glass. The second is a thermally insulating glass called Smart Glass.
Brite is ramping production and building pilot greenhouses utilizing the Solar Glass in Europe and in the USA.
What are we developing?
Brite develops unique nanomaterials and deposition techniques.
Brite has developed ink-jet printable formulations of TiO2 (Titanium Dioxide) and WO3 (Tungsten Trioxide) that result in uniform coatings that are patterned and can be tightly controlled in terms of thickness and matrix structure. These coatings are essential elements of the functioning of the Solar and Electrochromic glass. Future applications may include electrodes in batteries, thermochromic glass and displays.
Brite has developed an electrolyte material, which is ink jet printable and converts to a solid state. This material has profound benefits as compared to traditional liquid or gel type materials, especially in the area of reliability in outdoor applications. The hybrid organic-inorganic compound creates a nanotube structure which has excellent thermal insulating qualities. Initial test data shows a lamination of two pieces of glass with the electrolyte in between has 3-4 times better thermal insulation that dual pane low E glass windows.
This electrolyte can be used as an active element in the production of Electrochromic or Solar Glass or as a simple insulating material in the production of a low cost thermal insulating laminate called Smart Glass.
Electrochromic glass allows the light and heat transmission to be electronically controlled such that during the summer, the heating of the building from the sunlight is reduced, and in the winter it is maximized. Controlling the Solar Heat Gain has dramatic effects in reducing the energy required in a buildings heating and air conditioning systems.
Smart Glass has the physical characteristics of single pane glass (thickness, weight, transparency) while providing thermal insulation 3-4 times better than dual pane low E Insulated Glass Units. This represents a paradigm shift in window and glass facade construction.
