Photovoltaic Technology Roadmap<br />
Latest technology trends in crystalline and thin-film solar cells: An overview on <strong>the</strong> PV industry<br />
up to 2015<br />
Get a clear picture of tomorrow’s winning PV <strong>technologies</strong>.<br />
Yole Développement announces <strong>the</strong> release of<br />
its latest photovoltaic research study, named<br />
Photovoltaic Technology Roadmap, which<br />
presents and analyses <strong>the</strong> latest tech-nology trends<br />
in crystalline and thin-film solar cells.<br />
The results were obtained as a result of a meticulous<br />
data collection process over more than 80 companies<br />
and R&D labs.<br />
There is no doubt that <strong>the</strong> government incentive<br />
programs helped industrial to achieve, step by step,<br />
drastic cost reduction and performance improvements<br />
in a very short period of time but without real<br />
revolutions.<br />
The photovoltaic (PV) industry has also seen <strong>the</strong><br />
emergence of large scale production facili-ties,<br />
international R&D centres, and innovative equipment<br />
makers thus resulting in <strong>the</strong> im-pressive cost reduction<br />
Yole Développement knows. But if large production<br />
facilities can play <strong>the</strong> scale effect card to lower <strong>the</strong> cost<br />
of raw material and increase <strong>the</strong>ir yield, many o<strong>the</strong>r<br />
levers exist in order to reduce <strong>the</strong> production cost.<br />
Photovoltaic<br />
Strategies to reduce production cost<br />
Price reduction - impact of raw material<br />
Increased light trapping effect by<br />
improving surface structuring and<br />
texturization<br />

New Step<br />
Optimizing <strong>the</strong> passivation layer on<br />
both surfaces to reduce <strong>the</strong><br />
recombination losses<br />
In <strong>the</strong> next slides, fur<strong>the</strong>r details on each step will be provided<br />
“In this PV Technology roadmap report, we describes<br />
all <strong>the</strong> different aspects linked to pro-duction cost<br />
reduction, explains Arnaud Duteil, Market &<br />
Technology Analyst at Yole Développement: from<br />
cell structure innovations to modification of<br />
manufacturing proc-esses.” The microtech market<br />
research company in fact describes all <strong>the</strong> existing<br />
technolo-gies: From those developed by <strong>the</strong><br />
University of New South Wales (UNS W), to <strong>the</strong> metal<br />
wrap through (MWT) concept developed by <strong>the</strong> ECN<br />
and industrialized with Solland, to <strong>the</strong> new emitter<br />
wrap through (EWT) technology being developed by<br />
Bosh Solar.<br />
Conventional crystalline silicon cells could bump up<br />
against <strong>the</strong>ir <strong>the</strong>oretical maximum effi-ciency of 29%<br />
as soon as 2020. Sanyo Electric Co. Ltd., for instance,<br />
demonstrated ~23% ef-ficiency with a 10cm² R&D<br />
unit of its heterojunction with intrinsic thin layer (HIT)<br />
cells last year.<br />
It figures that thinner surface contacts, better<br />
transparent conductors, and lower defect density can<br />
improve performance by several more percentage<br />
points, to likely get commer-cial efficiency up to about<br />
as close as practical to <strong>the</strong> <strong>the</strong>oretical limit within<br />
about ten years.<br />
