Evaluating the Electricity Production and Energy Saving from Transparent Photovoltaics for Windows in Commercial Buildings

This work evaluates the energy benefit of transparent photovoltaics (TPV) for window application for two different donor materials. TPVs made of chloroaluminum phthalocyanine and heptamethine harvest energy from the near-infrared region of the spectrum and have the potential to reduce cooling energy. Due to the absorption property of the TPV material, energy-saving changes with location in the United States (U.S.). This work quantifies the energy savings using two types of TPVs in five types of commercial buildings and four different locations.
