companies/Research & Development
Blaubeuren, August 12, 2008 - centrotherm
photovoltaics AG is concentrating the know-how of over 25 experts 
from all areas of solar cell production in a cross-Group development 
project. This project, in which the company is investing a total of 
approximately EUR 10 million over a period of two years, aims to 
develop a new generation of solar cells, and the related production 
process, accompanied by significant enhancements in efficacy. In 
doing so, centrotherm photovoltaics benefits from the fact that 
essential parts of the value-chain relating to the manufacturing of 
solar cells and solar silicon can be realized within the Group. For 
example, the Group benefits from in-house access to experts from the 
areas of total-process development, metallization, wet chemistry, and
production line layouts. The International Solar Energy Research 
Centre in Constance provides additional research support. A new, 
improved design is being developed for the front and rear sides of 
conventional solar cells as part of the project. centrotherm 
photovoltaics has already intensively researched the requisite 
alternative process routes and their cost structures in an initial 
phase of the project, and has significantly improved them in the 
laboratory. The optimal process sequences for multi- and 
mono-crystalline solar silicon for mass production will now be 
prepared over the coming months.
"We aim at an efficiency of at least 16.5 percent for 
multi-crystalline, and at least 18 percent for mono-crystalline solar
silicon," explained Dr. Peter Fath, Chief Technology Officer, 
centrotherm photovoltaics. "Our development activity also takes the 
structure of the manufacturing process into account to allow our 
customers to benefit promptly from the results. The continued aim of 
our research and development is to make a contribution to reducing 
manufacturing costs in photovoltaics."
Independently from the development of the next generation solar cell,
centrotherm photovoltaics has registered successes in optimizing 
processes for conventional solar cells. In this area, improvements 
have been achieved with the thermal diffusion process to manufacture 
cell diode structure. This allowed significant improvements in the 
degree of efficiency to be achieved particularly for 
multi-crystalline silicon with low output quality.
