■ 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.

■ Using the desert for solar power generation -- Japan's technological achievement with batterie s and power lines
A massive concept to install a large-scale solar power station in the desert and distribute the power to the surrounding countries has been set in motion. After considering the land area, sunlight duration, and technological issues, the International Energy Agency (IEA) plans to embark on this venture in the Sahara and Gobi deserts staring next year. Towards the realization of this concept, there are great expectations on Japan's technology of excellent solar cells and electrical power lines.

■ Taiwan increases production of solar cells.
Taiwan widely known as the "silicon island" due to its large manufacturing plants for semiconductor devices now aims to become the "solar island", shifting its focus to solar panel production due to the ever declining prices of semiconductor products. Investments are surging and will eventually surpass solar cell production in Japan.

■ Chemical Industry News Special: Organic EL Solar Cells
The necessity of organic electroluminescence (EL) is rapidly expanding. According to the Yano Research Institute, the shipment of organic EL panels in 2008 is expected to be 7.3 times higher than last year's 110 million sheets. Assuming a similar increase in total revenue of 42.1%, it can easily exceed last year's 92.4 billion, reaching around 100 billion in profits. In the latter half of 2007, the increase in use of EL as the main display in cellular phones shows the growing need of EL panels in the industry.

CEATEC 2008
TDK: Implementation of solar and battery cell combination for electric power supply system will not use silicon but DSC for the solar cell component. The organic dye will be anchored on ZnO using a non-sintering, low temperature process. So far, an efficiency of 7.9% has been attained.
CEATEC Japan 2008 , a cutting-edge IT & electronics comprehensive exhibition, was held from September 30 to October 4 in Makuhari Messe. Including silicon technology, although there weren’t a lot of solar cell technologies on display, there were a lot of people having a great time in this marvelous event. For those who’d like a taste, today is the last day. To the organizers and participants, great job!

Nanotubes
This video was released by EPFL.
Nanotubes fabricated using a similar method (via anodic oxidation of metals) applied for DSC technology were previously reported in the following patent released in 2005.
Title of Invention: Electrode and Functional Elements
Inventors: Takaya Kubo, 朝野 剛、錦谷 禎範
Applicant: ENEOS
Patent Publication Number: 2005-150278
While we’re at this topic, the first to apply TiO2 nanotubes for DSC were I and former Kyoto University Professor Adachi (at around the same time). To ensure priority over this work, I published the “humble” paper listed below. Thankfully, until this day, it has been cited a total of 72 times. (^_^)
