    Transparent solar glasses: the future of renewables

    Researchers have set new performance records for transparent solar cells

    The new frontier of renewable energy production are transparent photovoltaic panels. These are panels that go to replace the glass in the windows, canopies and parapets of the balconies, greenhouse structures and which allow sunlight to filter inside the structure while producing energy.

    The current situation

    There are two different types of on the market transparent photovoltaic panels: the former are traditional photovoltaic panels, however formed by two layers of glass, both above and below, inside which normal photovoltaic cells are enclosed. In this case the cells are visible, but the light is able to penetrate from the transparent areas where the cells are not positioned. The latter, on the other hand, are real transparent photovoltaic glasses, without the presence of visible cells, which are able to produce photovoltaic energy thanks to the properties of the material they are made of (with silicon gel, organic-based or graphene-based).

    Pros and cons of transparent solar glasses

    The transparent photovoltaic panels they integrate very well in any architectural context, have no impact on the environment and their installation does not require invasive interventions. On the other hand, they produce less energy than traditional panels.

    The latest research developments

    Researchers have set new performance records for neutral-colored transparent solar cells. Today we are at8,1% efficiency: it's a crazy leap if you consider the previous 2-3%. Also there transparency set an efficiency record with the 43,3%, thanks to an organic design based on carbon rather than conventional silicon. Continuous research and the latest technological developments predict the use of "quantum dots" (quantum dots), microscopic particles that have the ability to manipulate light to harness energy.
