The first speaker was Dr. Douglas Muzyka (Corporate Vice President & President for DuPont Greater China). His topic was “DuPont & Renewable Energy: Photovoltaics & Biofuels”.
First of all, Dr. Muzyka presented DuPont’s vision “To be the world’s most dynamic science company, creating sustainable solutions essential to a better, safer, healthier life for people everywhere.” Then he introduced “Three Growth Strategies”:
i) Put our Science to work
ii) Go where the Growth is
iii) Use the power of One DuPont
He explained the key drivers of BioFuels, i.e. Energy security / energy diversity, CO2 reduction, Sustainability, Low cost carbon and Best option for transportation market. He summarized Biofuels in 3 points:
i) Strong belief in the future of biofuels
ii) Committed to decoupling food and fuel supply chains
iii) Technology is still in its early stages but advancing rapidly
Dr. Muzyka introduced Photovoltaics Market and Industry. Then he stated the technology of Solar cell including:
i) Encapsulation
ii) Metallization
iii) Backsheets
Lastly, he said that we’re turning solar possibilities into everyday realities.
The second speaker was Prof. Junhao Chu (Member of the Chinese Academy of Sciences; Director of Shanghai Center for Photovoltaics, China) and his presentation entitled “Photovoltaic – a New Active Opportunity in China”.
Prof. Cui gave introduction of the photovoltaic industry and market development in China. The following photos show the distribution of Solar Energy in the World and in China, respectively.
Then he presented different technologies of solar cell. And he pointed out several problems as follows:
i) Backward Technology:
· Energy consumption for the world’s advanced level of 1.5 to 2 times
ii) Pollution:
· Tail gas recovery and circulating utility
iii) Small Industry Scale:
· The capacity is 400t and the actual output is 300t in 2006
iv) Cheap Substitute Technology
He mentioned “The a-Si Thin Film Solar Cell Industry is developing quickly because of low cost”. And “The module price may be 1~1.5 $ / Wp in the future with the development of technology and supply of crystal silicon materials.”
Finally, he summed up the key factors for technology development tendency:
i) Continuously improve the efficiency;
ii) Continued reduce thickness of wafer;
iii) Enlarge the economics of scale to reduce costs;
iv) Continuously improve industrialization technology.
The third speaker was Dr. Thomas Hinderling (CEO, Swiss Centre for Electronics & Microtechnology, Inc. (CSEM), Switzerland). His topic was “Solar Island”.
Dr. Hinderling described the energy coming the sun was enormous but area density of this energy (~ 1 Kilowatt per square meter) was limited. Therefore, he raised two problems had to be solved:
i) Very large “free” surfaces with high solar irradiation required to be found
ii) Solar energy required to be cost-competitive to today’s energy sources – without government subsidies
Needed surface for PV power generation to supply Hong Kong was almost its total area!
He proposed to use a huge Solar Islands on High Sea and/or on Land to collect sunlight. A prototype had being constructed in Ras al Khaimah, U.A.E.
