Concepts for high efficiency multi-crystalline silicon solar cells, part 2

Objective

The purpose of this project is to develop a good compromise between low cost and high efficiency for polycrystalline ingot-type silicon solar cells. On the one hand efficient laboratory cells will be made, using micro-electronic technologies to assess the limit of intrinsic possibilities. On the other hand there will be a trade-off with cost using industrially oriented technology for certain steps.


High efficiency and low cost solar cell modules are the 2 important requirements for the breakthrough of photovoltaics. Of course, efficiency also indirectly contributes to the overall system cost, because of the balance-of-system costs (BOS). The higher the BOS costs, the more important the role of efficiency becomes. The efficiency and cost of solar cell modules are sometimes conflicting parameters, because cheaper techniques of fabrication usually lead to lower efficiency.
The project goals are :
* a best (lab) efficiency of 15.5-16% on 10x10 cm
* an "industrial efficiency" of app. 15% on 10x10 cm
* The direct goal cost is < 1.5 ECU/Wp
A lot of attention will also be paid to the quality of the ingot material. Studies will be done to understand the difference in gettering mechanism on the different multicrystalline materials under study. In other words: the relation between structural, compositional and electrical properties of the substrate material and in function of the production step history will be clarified further.
