Photovoltaic glazing (PV glazing) is a revolutionary technology that turns sunlight into electricity and decreases energy usage in cooling, heating and artificial lighting.

The semiconductor-based PV cells are sandwiched between two sheets of glass. They are also known as solar cells. Although photovoltaic glass is not entirely transparent, it does allow some light to flow through. The buildings that use photovoltaic structures in their construction can generate a portion of their electrical needs.

Applications in construction

Photovoltaic cells (PV) convert sunlight directly into energy. Solar cells, measuring roughly 150mm, could generate up to 5 volts. To create a greater voltage, one would require a large number of PV cells to make a panel and a large number of panels to build an array. However, new technologies continue to enhance the application for PV cells in construction.

Building-integrated photovoltaics (BIPV)

Traditional PV systems have evolved into building-integrated photovoltaics to boost their efficiency and reduce the amount of materials utilised in buildings. These photovoltaic materials may be utilised in various construction settings, including roofs, facades, curtain walls and glass stairwells.

Building integrated photovoltaic glazing is a technique that enables buildings to generate power by converting the entire structure into a solar panel. The primary objective of this system is to maximise energy efficiency to meet the energy needs of the building. It is possible to design windows, skylights and facade shelves to receive more solar energy.

Due to technological advancements, BIPV may also be incorporated into existing building infrastructures. Additionally, it helps the development of net-zero energy buildings.

Given the current need for sustainable infrastructure, incorporating PV cells and PV glazing will be a game-changer. PV cell production has improved performance and helped reduced the use of construction materials while lowering carbon impact. The most common form of photovoltaic cell is crystalline PV, which can generate more electricity per square foot.

Advantages of PV Glazing

The advantages offered by PV glazing are as follows:

  • PV electricity is considered green or clean energy since its source is renewable and does not contribute to pollution.
  • Photovoltaic glass reduces the facility’s carbon footprint and improves the organisation’s reputation.
  • PV Glazing is visually pleasing and helps improve the infrastructure’s overall architecture.
  • PV Glazing aids in building cost-effectiveness. BIPV replaces some of the building materials and becomes a dual-purpose solution for construction & power generation. Instead of purchasing glass windows, it is sufficient to purchase photovoltaic glazing, which generates power and functions as windows. Therefore, BIPV systems reduce the cost of conventional structures.
  • PV Glazing can aid in the creation of zero-energy structures. Integrating renewable energy and energy-saving methods is crucial to the zero-energy construction paradigm.
