Sustainability 2008 We know what happened !!! www.jinkosolar.com Source : GTM Research

Reliability 0.7 % Average 1.7 % A University of Arizona study found annual degradation levels of 1.7% on 1,900 modules in the field for 3 - 18 years. www.jinkosolar.com

Consistency Repeatability Average ~ 22 % www.jinkosolar.com

For a typical 20 MW, 1 % less Energy Yield Surprises !!! “Oh no! our modules are down 40%, we think it is potential–induced degradation” ‐anonymous module manufacturer, 2010 For a typical 20 MW, 1 % less Energy Yield 10% Profitability Loss www.jinkosolar.com

5% more peak power per module R&D: Projects R&D efforts are sharply focused on two emerging technologies: 1. Next Generation Technology: High-Power PERL Cells PERL cells use a thin ceramic film layers on the back of the cell to dramatically increase solar cell voltage (Voc) 5% more peak power per module Standard Cell Cross Section PERL Cell Cross Section Front-side of cell All metal coverage ( ) with full area contact ( ) Limited Voc and Power Point contact area ( ) with ceramic film passivation ( ) Increased Voc and Power

3% more peak power per module R&D: Projects 2. Next Generation Technology: ABC (All Back Contact) Solar Cells & Modules ABC cells place all of metal contact strips at the back of the cell Triple Benefit: Less metal on the front means more sunlight on the cells Simplified back connections reduce power loss & improve reliability Improved aesthetics 3% more peak power per module Standard Cell ABC Cell
