■ The birth of the Solar Cell Brigade, Fostering a national strategy
With the worldwide demand from solar cells as a backdrop, a new industrial structure with solar cells as its core arose. Also known as the 21st century industrial cluster, the Solar Cell Brigade came out of these circumstances. These companies realized the need for cooperation to survive and get an edge in the rapidly growing worldwide energy market. Considering the market forecast for low-carbon demand, the Japanese industry recognizes that this is a huge chance that they should never be passed on.

■ Solar Cells (5) : Dye-sensitized Solar Cells, A new power source for PC's
"We have good weather today. I should leave this outside under the sun." And we're not talking about laundry. In the workplace after several years, it is possible that notebook computers will be recharged using sunlight.
By 2010, Dai Nippon Printing Company aims to produce solar cells as auxiliary power supplies for computers and cellular phones. Aside from decreasing power usage in the workplace, it will become possible to use electronic devices outside simply by gathering power from sunlight. They plan to use dye-sensitized solar cells. It is composed of thin layer of dye coated on top of a plastic sheet, which is tightly sealed. Similar to plants in photosynthesis, these devices generate electrical energy when light is absorbed by the dye. They are more lightweight since metals are not used and only a thin layer of dye is necessary to produce electricity, while most silicon and other metallic compound-based panels require heavy glass.

■ "Rechargeable-wear"
Product name: Film-type Dye-sensitized solar cells
Product details: This solar cell can be sown on clothes to be used as auxiliary rechargeable device for celfones and digital music players.
Recently, Tokyo Tamago on TV Tokyo featured DSCs attached on a jogging suit as a "rechargeable-wear" by Gunze. The prototype still needs to be improved both aesthetically and efficiency-wise. The reporter who wore the jogging suit on a slightly cloudy day was able to get a voltage output of 0.994 V but complained about the wires sticking out and also mentioned that the suit is still a bit uncomfortable. Gunze aims to release this product by 2010.

Lecture by Prof. Michio Kondo in RCAST
Prof. Michio Kondo, the director of the Research Center of Photovoltaics in the National Institute of Advanced Industrial Science and Technology (AIST), was kind enough to give the staff and students of RCAST, Univ. of Tokyo a lecture last Friday.
Title: A low-carbon society based on revolutionary solar power generation
Date: November 7th, 2008 (Friday), 14:30-17:55
Venue: RCAST Bldg 4, 2nd floor Seminar Room
Prof. Kondo's lecture was extremely informative, covering a wide range of solar power technologies, their history, current status and future perspectives. He gave a fair analysis of the different types of technologies, ranging from silicon-based, multi-junction devices, organic thin films, and DSCs. I really enjoyed his lecture because I was able to understand his lecture quite well, despite it being in Japanese because he explained everything simply and concisely. I cannot wait to attend another lecture such as this. (^^,) - Joanne

■ Modern times close-up: Why is Japan, the leader in solar cell technology, lagging behind in the world market?
According to Makoto Kyomizu of the Research Department of the Development Bank of Japan, "What is common in the rapidly growing Germany, China and Indian companies is that they pooled their investment money to world-wide scale and became huge in one burst. They collaborate with other companies if they lack the technology. Unfortunately, this is not a strategy that Japanese companies want to adapt."

■ TV program
Recently, a "non-fuel" movement is spreading worldwide. In the heart of this, solar energy has become a main focus. In order to provide the demand of solar panels in Europe, several new manufacturers have sprouted up in countries such as China and India. Japan's Sharp Corporation stating that "Solar Energy is the next oil field." will not only produce solar panels but will actively participate in the solar power generation business by implementing non-conventional strategies. Also, Showa Shell Sekiyu, sensing the impending crisis of petroleum, has proposed a new strategy to give petroleum a backseat and instead promote solar energy business in the frontlines. A discussion involving solar energy in the forefront of fierce competition in the world's expanding market.

■ Daido Steel - Streamlines photocurrent generation, plans on using concentrators to up power generation by 1.6%
Daido Steel developed a light-concentrating solar power generation system. From December this year, Daido plans to establish a plant in the Aichi Airport New Energy Exploration Research Area of Tokoname City, Aichi Prefecture. From next year, actual experiments and implementations will be undertaken for a four-year period.
The system developed by said company consists of a dome-shaped plastic lens used to concentrate light to 550 times and the power from this light is delivered to a "power generation cell". A 165 mm lens is partnered with a small 7 mm power generation cell. Since it can gather stronger intensity sunlight, this system is 1.6 times more efficient than previous systems. In addition to the smaller area of the power generation cell, the feasibility of high-volume production of the lens, the cost of this system is almost the same as previous products.
