The main research problem, which ML System plans to solve in the next stage of the project, is related to determination of the optimum conductive parameters of layers. Multiple glazed unit invented by ML System (researched in stage I) fulfils its utility performance characteristics, however, the glass with tin oxide coating doped with fluoride (FTO SnO2) supplied for its manufacturing may be purchased only with the resistance of 8 or 240 ohm. For application in glass pane, 240 ohm glass is possible, and the heat output of such glass panel depends on the distribution of the electrodes, moreover, it is only possible to purchase a layer applied on glass. The scope of research works relating to multiple glazed panel, planned for the next stage before the commercialization, will cover primarily the research of the resistant layer, that generates heat by flow of electric current (new, innovative layers could be used as photovoltaic filler - or enriching the unit with additional functionalities e.g. to control its transparency, which is currently the subject of other research works). The planned research will be aimed at optimizing material and electrical parameters of heating layer for use of other conductive components - e.g. indium oxide doped with tin as a layer of ITO, silver oxide, tin oxide doped with fluoride and carbon materials such as graphene, graphene flake, carbon nanotubes and other composite materials. For these materials the application methods will be tested, e.g. screen printing, ink jet, or optionally (in case of a purchase of appropriate research equipment by magnetron methods). Also laser ablation methods shall be examined, and different kinds of electrode deposition technologies will be researched (e.g. ultrasonic, ink jet).

Examined and determined will be the substrate optical parameters with overlaid thin resistive layer, i.e. reflectance, transmittance, absorbance in a wide range of electromagnetic waves (from UV to medium infrared). Also the absorption and transmission coefficient will be determined. Also transparency of layers as a function of length of the electromagnetic wave will be examined. Also the thickness of thin layers and their chemical composition will be determined. The micrography by scanning electron microscope with X-ray adapter will allow for detailed examination of surface morphology. ML System laboratory team has prepared a range of tests that will be clarified after the purchase of research equipment for the Photovoltaic Research and Development Centre.

The objective of ML System’s innovative technology is to contribute to solving one of the European’s main environmental problem i.e. global emissions of carbon dioxide (CO2) from fossil-fuel combustion. ML System intends to reduce an energy needed to heat (and air condition or other uses requiring electrical energy) commercial and institutional real estates (at the first stage of market introduction), what will be an important step towards achieving the EU goals for low-carbon economy. It will be possible thanks to MLSYSTEM, that is a novel multifunctional window, which is a façade glass unit for building integration with 3 main features:
• provides semi-transparent heating of the interior of the building,
• uses semi-transparent photovoltaic to generate electricity and
• delivers superior thermal insulation properties of the whole system. Its implementation will allow to reduce one of the main problem of real estate industry i.e. heat losses caused by window’s heat transfer and air leakage.

Implementation of ML SYSTEM’s innovation will greatly reduce problems associated with CO2 emission. The basis of MLSYSTEM’s value proposition is the fact that buildings account for over 40% of primary energy consumption and 36% of Europe’s CO2 emission.[Report: Glass for Europe]. If we consider that 30% of energy consumed in buildings is used unnecessarily or inefficiently [Report: U.S. Environment
