    There are many materials, techniques and technologies ready to announce their arrival on the solar PV scene. All will stretch the solar PV focus in some way. Some are very new and far-reaching, while others are focused on addressing immediate issues. But all are ready to be implemented within the next few months. Joyce Laird rounds up the ones to watch.

  • Building Integrated Photovoltaics (BIPV): innovation puts spotlight on solar
    In a time when solar PV is characterised as being a prohibitively expensive alternative form of energy (subsidies notwithstanding) one application area that could make a real difference to perceptions is BIPV (Building Integrated PV). This application can effectively enable building owners to save on construction costs of new buildings while at the same time generate a portion of their own electricity. Further progress requires a high level of innovation to truly bring solar PV into buildings, while making the technology even more affordable. Fortunately, there are signs that such inventiveness is now making a difference.

Solar and wind power generating trees

11 March 2009

Using biomimicry techniques, an artificial tree or plant structure can function as a passive solar and wind power harvester, according to SolarBotanic.

Biomimicry and nanotechnology are integral to SolarBotanic’s technology where specifically designed nanoleaves are incorporated with a combination of biomimicry and advanced nanotechnologies to generate electricity.

SolarBotanic’s energy harvesting process utilises three types of technologies: photovoltaics (PV), thermovoltaics (TV) and piezovoltaic (PZ) – a direct conversion of kinetic energy into electricity.

The technologies are utilised in the nanoleaf to convert solar radiation (light and heat) into electricity. In addition, the leaf petiole or the stem, and twigs comprise nano-piezovoltaic material producing electricity from movement or kinetic energy caused by wind or falling raindrops.

According to SolarBotanic, an average tree with a canopy of approximately 6 m2 can generate enough energy to provide for the needs of the ‘average household’.

SolarBotanic retains patents and has patents pending covering biomimicry, nanoleaf technology, energy transfer materials and process, and has confirmed proof of concept criteria as required by investor groups. The company says it is interested in talking to potential partners to take the project from the R&D phase to full commercialisation.
