Typical Module Production Theoretical Maximum

► Semprius current module efficiencies are higher than other technologies’ theoretical maximum

► Helps lower balance of system costs and enable very high energy densities

► Semprius on the leading edge to even higher efficiencies over the next five years

Current ~34% >37% 2016

Focus on Reliability

Modules are designed and manufactured for reliability:

►Cells operate at low temperature and current

►Thin film interconnects – no wire bonds

►Uniform cell heating – no hot spots

►Cells highly redundant and modules tolerant of individual cell failure

►No measureable degradation after 2 years on sun in field study

Focus on Performance Narrow Module Efficiency Distribution

► Measured on demonstration system in Puertollano, Spain

► Efficiency distribution of 40 modules measured by ISFOC using a flash tester

► Mean of 33.3%1; standard deviation of 0.6%; no sorting of cells during production ► Enables very low string losses
