Project objectives

  • Cost reduction (down to below 0.5 €/Wp at system level, ensuring electricity prices well below 0.08 €/kWh in sun-rich areas), and reliability increase,

  • Improved lifecycle of PV systems (down to energy pay-back times below 0.5 – 0.7 year in southern parts of Europe).

  • Achieve solar cells with 14% stable efficiency, leading to the demonstration of reliable production size prototypes module at 12% level

 

About Fast Track

The thin-film silicon (TFSi) technology has gained increased importance with the expansion of the technology to a "next-generation", by combining amorphous and micro- or nanocrystalline silicon in a tandem configuration to "micromorph" cells.
The work performed in Fast Track covers all aspects that interact and determine or influence the efficiency of micromorph photovoltaics, and its transferability to industrial applications. In recent years many new approaches have been individually introduced.
Thereby cross-cutting areas and technologies extend over processes, modelling and design. The active participation of industrial partners represents an added value to the activities.

Fast Track will use the complementarity of these approaches to improve the efficiency of test cells and modules from pilot production lines. A list of the novel approaches and their individual influences and interactions is given in Figure 1. The device optimization will be performed according to this scheme. There are several factors that enter into the evaluation of a certain PV technology and that determine its choice:

  • the stabilized module efficiency;
  • long-term performance and guaranties;
  • cost/prize per generated power (€/W) of the modules and the balance of the entire system;
  • the annual energy yield (kWh/kW) that determines the cost of the generated electricity, and, if applicable, the reimbursement from feed-in regulations;
  • special module features, e.g., semi-transparent or flexible modules; for such applications, other aspects, besides electricity generation, are desired and valued in prizes, like, e.g., special architectural designs or individual considerations.
