Solar Energy industry kept rapid growing so far. By a serious impact of Financial Crisis, however, negative growth is expected in 2009. The reporter has asked Mr. Ellick K.J. Liao, President & COO of Gintech Energy Corp., a leading manufacturer of exclusive Solar Cell in Taiwan, to talk about an impact by Financial Crisis and strategy toward future.

Q) The Solar Energy industry seems hit the wall recently by an impact of Financial Crisis in spite of having run in high gear so far ?

A) Global production volume of Solar Cell in 2008 was expected to reach 6G to 6.5GW level before the Financial Crisis while it has toned-down to around 5GW afterward. Especially, in European market serious drop occurred so that we have suffered severe affect as we have 100% been dependent on exports. To cope with such situation, the plan to expand production capacity of Solar Cell up to 1.5GW in 2010 was rushed into change. The time of completion of third factory of ours, being scheduled in October, 2008, has been blown off to delay the timing of our target to reach 1.5GW production for one year period.

Q) How do you manage Solar Cell business hereafter ?.

A) We will concentrate our effort to extend much severe inventory control, to raise quality level and to cooperate more closely with affiliated companies. As to inventory control, we have reduced the time required after production to ship out period down to 10 days from previously be 30 days. To raise performance level, we will increase Conversion Efficiency by 1 point higher than that of rival maker up to 16.6% (see the attached Article). Even by raising the Conversion Efficiency, we will keep the same price. Closer cooperation will be materialized by having invested to Eversol Corp., an exclusive Wafer manufacturer in Taiwan. While we have so far purchased from 7 overseas Wafer manufacturers, we will , thus, bring local purchase into a view.

Q) When do you think it will recover self-reliant growth in Solar Cell market by overcoming the Financial Crisis ?

A) To expand the market, it is essential to reduce production cost. At this moment, Solar Cell system costs US$7.00/W, and power generation costs US$0.46/kW per hour. To enable us become self-reliant, without any Governmental support, it is essential to put equivalent Grid Parity of Solar Cell to existing electricity into practice, which is to say, Solar Cell system shall become UD$3.8/W, power generation cost to be US$0.24kW per hour. Judging from a forecast by Demand/Supply situation, it will become practical in 2015 or so.

Q) Road map to materialize such high Grid Parity is already built ?

A) There is nothing else but to reduce production cost. At this moment, production cost of Polycrystal Si costs US$25-30/Kg, that of Wafer is approx. US$1.45/pce, that of Cell is approx. US$1.5, also that of Module is known as approx. US$2.1. Besides reducing those production costs, it will be required to raise conversion efficiency, and further, to cut down installation cost. Target of the reduced conversion efficiency shall be 18% in case of Polycrystal Si type Solar Cell.

Gintech, Taiwan, start shipping Solar Cell of Polycrystal Si of 16.6% Conversion Efficiency

Gintech Energy Corp., an exclusive Solar Cell manufacturer in Taiwan, will start to ship gDouroh, Polycrystal Si type Solar Cell in March, 2009. Said company will attain such globally highest conversion efficiency by using Polycrystal Si type Solar Cell being processed by existing configuration, material and process.

Incidentally, average conversion efficiency at this moment is 16.4% or higher. gBefore the shipment of those products, the average shall be improved to 16.6% or higher in averageh (told Mr. Harry H. H. Kuo, Product Manager/Technical Manager of the said company). Toward future, the average conversion efficiency shall be targeted to 17.5%.

At about the same price as existing products
For those Cells to start shipment in March, none of special manufacturing process is innovated. By using the similar production process as the existing products, higher yield percentage can be expected. As a result, those Cells having approx. 1 point higher conversion efficiency can be produced at almost similar cost as it is now. Within one year from starting shipment of such products, all Cells being produced shall be shifted to such new type. Current yield rate of 97% shall also be raised to 97.7%.

Outer dimensions of the new Cell is 156 x 156mm, thickness of the base is 180~200ƒΚm.
The new conversion efficiency is measured by Fraunhofer ISE (Instituts f & uuml;r Solare Energiesysteme). Incidentally, at Gintech, conversion efficiency is categorized into 42 ranges within a tolerance of 15-17% to when ship out.

Polycrystal Si type Cell and Color Cell are also available as well
Besides the Polycrystal Si type, conversion efficiency of the Single Crystal type Solar Cell has also been raised by improvement up to 17.1% or higher.

In addition to this, Color Cell of looking like Green, Purple, Gray or Silver is also available by adjusting the surface layer. Conversion efficiency is still same as those normal cells to attain as high as 16% at the best. Application to BIPV (all-in-one as Building material) is envisioned.
