Description of the organisation

DRACULA Technologies is a start-up company created in 2011, which is aimed at designing and manufacturing flexible photovoltaic (PV) solutions with their specific electronic to power nomad devices. H2020-NMBP-07-2017

The company was created as a result from the collaborative French project SOLARJET (FUI with two companies and an academic partner: ARDEJE, Hutchinson and CEA-INES, from 2008 to 2011, eligible budget: 2,280 M€) aiming at developing and manufacturing low cost printed PV cells. The company currently commercializes the first generation of flexible photovoltaic solutions called DRACULA POWER (inorganic photoactive materials) and develops, at the same time, the second generation of flexible photovoltaic solution based on organic and hybrid materials. The company has currently 6 persons as salaried employees.

Significant infrastructure / major items of technical equipment

Since its creation, DRACULA TECHNOLOGIES has invested in equipment to be at the cutting edge of technology. This equipment is described hereafter focused on those that will be used for the needs of MMAMA project. For most of the tasks involving DRACULA TECHNOLOGIES the sheet-to-sheet pilot line will be used. The layers applicator is PC controlled (speed, rate, start point, end point). Currently, the maximum layer dimensions that can be produced with this equipment 5*5 and 10*10 cm². The goal of DRACULA TECHNOLOGIES is to reach a surface of 30*30 cm². DRACULA TECHNOLOGIES uses a solar simulator for industrial and laboratory applications requiring an intense and very stable light source. Two types of filters are available:

  • Air Mass filters precisely reproducing the terrestrial solar spectrum;
  • UV filters (UVA or UVA + UVB) to obtain the maximum UV radiation responsible for aging.

In the framework of the development of OPV cells and modules, DRACULA TECHNOLOGIES prefers using Air Mass Filters making possible to reproduce precisely the terrestrial solar spectrum. It is particularly suitable for testing photovoltaic cells or solar collectors.
