Objective
Objective and problems to be solved:
The project aims to develop monocrystalline silicon cells of over 20% efficiency by methods which lead to an overall reduction in module cost towards the 1 /Wp target of the Work Programme. Furthermore, the use of very high efficiency cells and hence modules can reduce balance of systems costs through lower area requirements, lower structure costs, less module interconnection and less installation time. This can contribute to achieving the 3/Wp PV systems cost target. The objective is to develop new monocrystalline silicon wafer substrate materials that do not suffer light induced degradation, and to use these wafers to apply laboratory concepts to industrial production to fabricate solar cells over 20% efficiency in 150 m wafers with a cost saving of 30% module cost compared to present manufacturing costs. Description of the work: The challenge is to develop materials which are not as good in quality as the highest quality FZ materials but which are cost effective and of sufficient quality to make 20% efficient solar cells. Alternative processing routes must be developed which can be carried out at high throughput and low capital and consumable costs but yet give high efficiency solar cells. Specifically the technical objectives to be achieved are:- Fabrication of Ga doped Cz wafers which give the same solar cell efficiency when processed with the RP-PERC structure as FZ material- FZ wafers which are grown from lower cost lower grade feedstock to give wafers of the same cost as boron doped CZ wafers on a /Wp basis.- Laboratory cells of 20% 4 cm2 efficiency grown on Ga doped CZ silicon material and on low cost FZ material- Specification of processes based on either Ga doped CZ silicon material or low cost FZ material which give 20% efficiency cells in high volume industrial processing- Demonstration of 20% cells on 100 cm2 made by a variation of the laser grooved buried grid cell process on an industrial production line using either Ga doped CZ silicon wafers or low cost FZ silicon wafers. Wafer thickness less than 150 µm.- Evaluation of the process economics which show that the developed cells will be 30% cheaper than present cells and the manufacturer of such cells creates no environmental hazards. Expected results and Exploitation plans :The final deliverable is a 20% silicon cell, 100 cm2, 150 m thick, made on an industrial processing line at a cost 30% below present manufacturing costs. The consortium consists of three industrial partners and two research institutes, reflecting the industrial nature of the project and the high potential for commercial exploitation.
