Konica Minolta Holdings, and Konarka Technologies have announced that they had already started in April 2010 compared to thin film organic solar ThinkPad T60 battery ThinkPad R32 battery cells to jointly develop, manufacture and marketing, has signed a package of business and cooperation agreement capital. The two sides plan is to achieve common development, if the year in 2012 to determine the feasibility of your business, it will set up two companies in Japan, a joint venture for the promotion of organic thin films solar cells for mass production. Capital, Konica Minolta will be invested 20 million dollars conac United States.
Organic thin solar cell is a kind of semiconductor materials through organic pn junction or PIN junction composition, and then converted into light output of solar cells. Characterized by thin, lightweight, flexible, color, freedom of choice and higher volumes can be produced by volume, it should significantly reduce manufacturing costs. However, there are many different topics. Conac reached an organic solar cell thin film based products, but the module conversion efficiency is only “3% ~ 4″ (CONAC executive chairman and founder Howard R. Berke), lower than the existing number of solar cell. In addition, there are topics such as life expectancy is shorter. Inspiron 5150 battery Inspiron 700m battery
The common development “to achieve an efficiency of 10% module conversion and 10 years of existence as the target” name (Konica Minolta President Executive Matsuzaki is to years). The two companies plan is to know if we could achieve by the year 2012 target, will establish a joint venture, before and after mass production in 2013, to expand sales in Asia as the center. Matsuzaki said “(manufacturing plan since the beginning) 5 years for the 500 billion yen in the scale.”
Konica Minolta has been with General Electric U. S. development of lighting products organic EL launched cooperation). The desire to develop an organic thin film solar cells because “(thin film organic solar cells) and organic EL lighting products is expected to create synergy” (Matsuzaki). Make specific reference to basic technology from Konica Minolta ( 1) Water and oxygen have a high barrier thin-film technology, (2) in a variety of business accumulating optical “light management” (Matsuzaki), (3) in photo film industry, the combined volume of technical roll coating, and (4) a variety of organic materials, technology development, cells of lighting products and organic EL thin film organic solar are two aspects of advantage.

On the other hand, is very concerned about the type of non-silicon solar cell is composed of CdTe solar cells and CIGS type classes (see site report). However, the Konica Minolta view Matsuzaki, the use of such compounds, materials, solar cells is of short duration. Matsuzaki also stressed that “There was a time composites have been used as a copier and sensible body. However, toxicity and performance issues such as the existence of problems of instability of amorphous silicon and possibly organic photoconductor (OPC) market. It is estimated that the field of solar cells will also appear in the same situation. ”
During the year 2010 to reach 10% efficiency of conversion of cells is the touchstone of
The two companies established in 2012 in the year preceding the performance target on the issue of life takes shape. Conac Berke said, “is only used in the package with Konica Minolta high barrier film is a measure, it will be for an initial term of five years of outdoor life up to 10 years.” Sony VGP-BPS8 Sony VGP-BPS8A
In addition, the objectives of efficiency of conversion there is a major obstacle. Currently, many companies and research institutions are actively engaged in the development of organic thin film cells, solar conversion efficiency also continued to improve. In the products already announced, the United States of Solarmer efficient energy conversion of 7.9% in units ranked first, and other companies have already reached more than 7%. In addition, the majority of these companies think we can achieve in 2010 years, 10% conversion efficiency of cells.
Conac is also one of them. Conac Berke said, “Research institutions received 7% conversion efficiency of cells. At the end of 2010 will be able to reach 9 ~ 10% conversion efficiency of cells and 5% conversion efficiency module. “A1078 A1045
