We1 believe that the best approach to lowering the cost of solar electricity and solving the great engineering challenge of achieving solar electricity at a $1/W (per installed system) or “Grid Parity” (without subsidies) is to manufacture modules made of a single crystal, or highly textured, c-axis aligned relatively large grained thin-film semiconductor deposited on an inexpensive substrate. Specifically, our “kerf-less,” modified liquid phase epitaxy technology allows for the growth of continuous (single crystal or highly textured, large grain) semiconductor ultra-thin films on ordinary (soda-lime) glass for inexpensive and efficient modules.
Very simply, our patented technology has the following advantages which make it ideal:2
- Higher light conversion efficiency (due to single crystal, or high texture and large grain)
- Less semiconductor material use (due to thin-film and inexpensive substrate)
- Low temperature film deposition while still allowing for high quality material (due to eutectic manufacturing method)
- A tandem (perovskite/silicon or germanium for example) solar cell structure that could achieve efficiencies of up to 45%
In addition to solar cells, Solar-Tectic™ plans to produce sapphire glass, consisting of a thin layer of sapphire (crystalline Al2O3) on ordinary soda-lime glass or other kinds of glasses. This product can be used as a substrate for deposition of highly oriented semiconductor films for PV purposes, as well as for display applications like covers for smartphones, etc.
Solar-Tectic™ also plans to develop its proprietary technology for Light Emitting Diodes (LEDs), Organic Light Emitting Diodes (OLEDs) and Field Effect Transistors (FETs) used in displays, as well as Solar Inverters (GaN on Si or sapphire/glass).
Solar-Tectic™ derives its name from the word ‘eutectic’, a fascinating physical phenomenon occurring when two elements — such as silicon and a metal – are combined to form an alloy. Two of our patented technologies, ‘1c-Si Eutectic’, and ‘1c-Si Laser Eutectic’, take advantage of this phenomenon for low temperature deposition of films and with excellent material quality. We have a portfolio of proprietary technologies, including one in which single crystal silicon nanowires are grown on ordinary (soda-lime) glass for photovoltaic and other applications; and another for manufacturing superconducting tapes for use with solar modules for efficiently transferring solar energy to and from the modules and to and from public utility electrical power grids and computer-based, automated electrical power “smart grids.”
At Solar-Tectic™ we don’t much like the word ‘disruptive’. But we believe that our technology will be transformative in the solar and display industries, improving living standards and contributing significantly to the fight against climate change.
