The PV EXPO in Japan is one of the most noted professional PV trade shows in the world, as well as the most important business platform of the Asian photovoltaic industry. There are 570 exhibitors from around the world participating this year, displaying a full range of technologies for materials, equipment, solar cells and modules, photovoltaic systems and integration schemes. It is a must-attend event for vendors who wish to break into the Japanese and Asian PV markets.

AUO will be exhibiting the high-efficiency module Mono 245W, which is capable of generating more power on space-limited rooftops with an impressive conversion rate of 14.7%. It weighs merely 20kg, around 15% lighter than modules of the same size on the market, and is also easy to install. Customers have the option of choosing black or white colored modules to match the design of their buildings.

In its energy business, AUO obtains quality materials from M. Setek on the upstream side and supplies to photovoltaic system projects downstream to provide the most competitive total solution. The company will exhibit quality materials with high conversion rates at the PV EXPO to demonstrate its strategic position as an integrator of the solar industry supply chain.

As a major supplier to renowned solar cell companies around the world, M.Setek boasts leading technologies in Japan for upstream polysilicon and wafers with high conversion rates. It is one of the few global suppliers that can provide high quality and high-efficiency solar wafers. The Company is also among the first to employ diamond wire sawing and is capable of mass production. The technology helps increase conversion rates, eliminates the use of organic solvents to ensure eco-friendly production, and maintains cost competitiveness. M.Setek is also equipped with the technology to fully recycle its materials, taking its share of responsibility for maintaining carbon balance as a part of the green energy industry. At the PV EXPO, M.Setek will display several wafers, one of which, the N-Type mono-crystalline wafer, can be applied to the making of high-efficiency solar cells, with a conversion rate as high as 20-23%.

James Chen, AUO’s Senior Associate Vice President of the Solar Photovoltaic Business Unit, will be speaking at the Taiwan Photovoltaic Industry Forum on the morning of March 4 during the PV EXPO. The topic is to be AUO’s Green Solutions.

AUO has actively invested in the solar business and understands the solar value chain from upstream to downstream. The Company has partners in Europe working on the development of several solar projects. In addition, a reliability lab for the testing of solar modules has been set up in Taichung, with its product quality certified by TÜV Rheinland, a global leader in independent testing and assessment services from Germany. The plan is to next launch solar business operating points in China this year. With its strategy focused on providing total solutions, AUO will cooperate closely with partners in the industry value chain to further develop the global solar market.
