4. 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 years.

5. Consistency
Repeatability
Average ~ 22 %

6. 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

11. NPC Japan 1200 – 1300 Cell per Hour Low Breakage Rates: 0.1% - 0.3%
High Throughput
Min Cell Handling

13. Texturing Reduced Optical Reflectivity Improved Light Absorption
PV Cell Architecture
Reduced Optical Reflectivity
Improved Light Absorption
Higher Cell Efficiency

15. 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

16. 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
