Making the Magic Happen
Photovoltaic (PV) technology generates the electricity directly from sunlight. PV modules work silently with no moving parts, minimal maintenance and no pollutant emissions. The heart of photovoltaic cell is a semiconducting material. When light strikes the semiconductor it creates positive and negative charge carriers, enabling an electrical charge to flow within
the material. The electro-optical properties of the semiconductor are prescribe the efficiency of these process
Building Integrated Photovoltaics (BIPV)
The price of a solar module represents around half the cost of an installed solar energy-producing system. Other costs include land, installation, logistics, electricity transition infrastructure, etc. Most of the electricity has to be conducted to the buildings. The buildings are responsible for over one-third of global final energy consumption and nearly 40% of total direct and indirect CO2 emissions.
Solar photovoltaic installations can be installed on the building skin allowing the possibility to combine electricity generation with other functions of the building materials. This will reduce the land and installation and electricity infrastructure costs. Therefore technology that can be used to reduce the costs of BIPV systems is of high importance
Colloidal quantum dots are semiconductor nanoparticles. They can be synthesized in the liquid phase and subsequently processed into thin films by employing cheap and abundant fabrication processes like spray painting, inkjet printing or reel to reel printing. The optical properties of these nanoparticles can be systematically modified by varying the composition and synthesis conditions.
