  1. Welcome delegates ICORE 2010 Renewables for Inclusive Growth Challenges – Opportunities - Risks Dr. Patrick Hofer-Noser CTO Meyer Burger Technologies AG

  2. Integrated Value Chain Enables Innovation & Standardisation Mono- /Multi c-Si Ingot-/Wafer Slicing Solar cells Solar modules Solar systems (1) SOLARISpowered by Oerlikon Systems September 2010, Meyer Burger Technology Ltd Note: (1) Strategic Marketing- & Distribution Agreement with Oerlikon Systems / Solaris

  3. Pace & Volume Business model World’s leading production equipment and processes for manufacturing Optimized processes along the entire value chain to lower kWh costs of solar electricity 900 Grid parity inthe most important markets 800 Thinfilm 700 September 2010, Meyer Burger Technology Ltd 600 500 GW 400 Installed c-Module 300 200 100 – 2009E 2010E 2011E 2012E 2013E 2014E 2015E 2016E 2017E Process, Costs & Market Development Experts in design and development of innovative PV products Source: Estimation MB Technology AG

  4. Total Life cycle Cost Total Life cycle energy production Customer LCOE = Processes Products BOS = Balance of System PR = Performance Ratio TCO = Total Cost of Ownership LCC = Life cycle Cost OEE = Overall Equipment Efficiency VDMA 34160 : 2006-06; SEMI E35, SEMI:E 79 KPI‘s $/kg Wp/m2 $/Wp $/kWh module efficiency Yield, Uptime, TCO Performance Ratio Longevity, BOS Main drivers on $/kWh From TCO and BOS to LCOE September 2010, Meyer Burger Technology Ltd

  5. Leverage effects in PV Equipment Yield 40% Uptime 12% CAPEX 7% Processes + Products Silicon 11% Wafering 11% Cell 10% Module 23% Module-Efficiency 100% A 10% higher Longevity of the PV System leads to a 9.5% lower $/kWh Messsysteme PV System Performance Ratio 100% Longevity of PV System 95% Balance of System 33% Financing 12% September 2010, Meyer Burger Technology Ltd $/kWh The utmost multiplicators in order to reduce $/kWh are yield, Module-Efficiency, Performance ratio and Longevity of PV System

  6. 2 1 Standards 4 Technology developmentwithin the box, between the box and out of the box 3 $/kWh TCO 1 TCO 2 TCO 3 September 2010, Meyer Burger Technology Ltd OEE = Overall Equipment Efficiency SEMI E79 TCO model created Mid-1980s Intel VDMA 34160 : 2006-06; SEMI E35 OEE created late 1960s, Japan SEMI E79 published 1999

  7. Diamond Wire - Next generation sawing technology • Faster processing • No slurry • Technology: direct cutting vs lapping • Less microcracks • Reduction of TCO by >10% September 2010, Meyer Burger Technology Ltd

  8. Diamond Wire Technology 0.58$ Slurry-sawn -12% Diamond wire-sawn 0.51$ Total runningcost Slurry/ Additive Wire/ Dia Wire Epoxy/ beam Utilities Personnel Service Amortization Slury based sawing Diamond Wire based sawing TCO Microcrack density and depth density depth depth September 2010, Meyer Burger Technology Ltd • Mono silicon wafer show a potential for slightly higher cell efficiency • Diamond wire allows accurate control of process parameter • Roughiness is better than slurry based cuts with less microcracks and on top microcracks with less depth

  9. Encapsulation -highest impact to lifetime Methanol Aceton Isopropanol Acetic acid VOC Organic Rest of Peroxyd Peroxyd Peroxy decompose because of temperature Becomes a radical Hydrogen abstraction of the Ethyl from EVA and cosslinking is started Crosslinking Verdampfung bei 100°C Gas separation EVA o o 7 8 September 2010, Meyer Burger Technology Ltd EVA 9 Analysis time (appr.weight/Mol) Mass spectrometer

  10. Encapsulation – Process stability and increase of lifetime September 2010, Meyer Burger Technology Ltd • Reduced cycle time -> lower TCO • Increased quality -> higher longevity • Improved PR 10

  11. Encapsulation – Process stability and increase of lifetime [€] TCO – Membrane lifetime - 650,000 € [cycles] 3 chamber process September 2010, Meyer Burger Technology Ltd • increased output by 40% -> lower TCO • adhesion EVA/glass and EVA/Tedlar > 40N/cm • Gel content 80% +/- 2,5% -> increased longevity • Membrane lifetime -> lower TCO higher uptime 11

  12. Live your dreams Thank you September 2010, Meyer Burger Technology Ltd
