Multifunctional glazing unit

A process for manufacturing a multifunctional glazing unit, comprising the steps of:

• i) providing a first sheet of glazing material and a second sheet of glazing material;
• ii) providing one or more spacer bars;
• iii) separating the first sheet of glazing material and the second sheet of glazing material with the one or more spacer bars to provide a cavity that is a heat insulating cavity sealed by at least on spacer bar;
• and
• iv) positioning a photovoltaic portion and a reflecting element between the first sheet of glazing material and the second sheet of glazing material to form the multifunctional glazing unit, with the reflecting element spaced apart from the second sheet of glazing material,
• wherein the photovoltaic portion in direct contacts with the first sheet of glazing material;
• wherein the photovoltaic portion comprises:
• a transparent region;
• a bi-facial region;
• and at least one photovoltaic element,
• wherein the reflecting element comprises an adjustable transparency reflecting element, and
• wherein the reflecting element comprises a plurality of rotatable slats.

A multifunctional glazing unit comprising:

• a first sheet of glazing material comprising a first face and a second face;
• a second sheet of glazing material comprising a first face and a second face;
• a photovoltaic portion;
• and
• a reflecting element;
• wherein the first sheet of glazing material and the second sheet of glazing material are separated by a cavity that is a heat insulating cavity sealed by at least one spacer bar;
• and wherein the second faces of each sheet of glazing material face towards the cavity;
• and wherein the photovoltaic portion and the reflecting element are each positioned between the first sheet of glazing material and the second sheet of glazing material with the reflecting element spaced apart from the second sheet of glazing material;
• wherein the photovoltaic portion in direct contacts with the first sheet of glazing material;
• wherein the photovoltaic portion comprises a transparent region, a bi-facial region, and at least one photovoltaic element;
• wherein the reflecting element comprises an adjustable transparency reflecting element that is sealed within the heat insulating cavity;
• and
• wherein the reflecting element comprises a plurality of rotatable slats.
