Light inside the handbag

Hermann Issa is keen on what he is doing: „Printed organic photovoltaic (OPV) is not only the third generation of photovoltaic technology but a technology with wow effect.“ As Director Business Development and  Sales at Belectric in Nuremberg, he is convinced of the unique features of OPVs, which offer maximum freedom of design and application.

Multifold integration possibilities can be explored, whether as inlays in glass, lamination on different materials such as membranes or textiles or direct integration in products. They can be shaped or bent and even be buckled at predetermined points.

From the outer to the inner values:  According to the design different unique shapes and looks can be realized – depending on the requirements and application areas. Whether in architecture or fashion – this generation of OPVs offers completely new possibilities for the integration of energetically active components. Application areas can be energy sources  for lights, transparent and coloured accessories for sports, leisure time and fashion. Also photovoltaic surfaces and product inlays in all kind of mobile and stationary devices are possible.

Light emitting wallpapers are also possible as special design with light emitting effects, where the OPV modules are the power station. Another application field is the garment industry with for example one-way safety jackets or applications that can be removed via velcros. Hermann Issa: “It is still not possible to wash OPVs. A real highlight in both senses of the word were OPVs in handbags which could charge cell phones or could illuminate the inner handbag as soon as you open it. “We are currently working on this kind of applications with partners in the fashion industry”, says Issa.

OPVs are offering increased production efficiency by low energy consumption during production and short energetic payback time combined with low to no use of rare materials. Furthermore, the OPVs are proven to be sustainable in terms of carbon footprint as well as end-of-life treatment.
Belectric provides a photovoltaic base material named Solarte which offers freedom for the design, shape and material. It can easily be integrated in applications and products. Under the influence of light and by the means of organic carbon based semiconductors, energy is generated in the OPVs. The solar panels are produced in an efficient printing process.
