項目說明  Project Description

產品：柔性 CIGS 薄膜太陽能電池 
Product: Flexible CIGS Thin Film Solar Panels

傳統的矽基太陽能電池容量大，對太陽光的轉換率可以達到20%，技術成熟，但是它的最大問題，是必須加工成堅硬的板塊狀電池板，這就限制了它的許多日常用途。柔性太陽能電池重量輕，而且可以折疊、捲曲，甚至黏貼在其它物體的表面，例如汽車玻璃，衣服等。團隊採用自行研發的技術，生產了柔性 CIGS （銅銦鎵硒）薄膜太陽能電池。

The traditional silicon-based solar cells is a mature technology. It has a good capacity and solar power conversion efficiency as high as 20%. However, its shortcoming is that it has to be mounded onto thick substrate modules, significantly limited its widespread applications. By contrast, the flexible kind of solar cells is light, foldable and bendable, and even can be struck onto the surface of different objects e.g. vehicle windows or clothes. The research team invented their own technology and developed their flexible CIGS (Copper Indium Gallium Selenium) thin film solar cells .

旭科新能源股份有限公司 Shinetech Co., Ltd.

2015年成立 Established in: 2015
註冊資本：5,200 萬元人民幣 Registered capital: RMB 52 million
估計產能：每年 2 MW Estimated capacity: 2MW/year
地址：浙江嘉興秀洲高新區 Location: Xiuzhou National High-tech Zone, Jiaxing, Zhejiang province, China

團隊發展的 CIGS 電池和組件科技，除了在香港中文大學組建了 CIGS 光伏系統，更於 2015 年在中國浙江省嘉興市秀洲區國家高新技術產業開發區成立了啟動公司「旭科新能源股份有限公司」，估計產能達每年 2 MW。公司現時擁有之以聚酰亞胺為基底的柔性 CIGS 薄膜太陽能電池生產線，是全中國第一、全球第二家，並擁有佔地 3,000 平方米的無塵室及 82 位員工（當中 20 位具碩博資歷）。此外，公司又獲得了嘉興市政府批准興建「省級企業研究院」及嘉興市「高新研究中心」。在 CIGS 太陽能電池研究上，團隊研發的科技取得了全球第三高的轉換效率。

The full-set technology of fabricating efficient CIGS cells and modules by the team leads to a high-efficiency CIGS PV system in CUHK, as well as a start-up company “Shinetech Co Ltd” in the Xiuzhou National High-tech Zone, Jiaxing, Zhejiang of China since 2015, with estimated capacity 2MW/year. The company currently has the first in China, the second in world production line of flexible CIGS thin film solar panels   based on polyimide substrate. The company currently has 3,000m2 clean room, 82 employees (20 of them have Master of Science or PhD degrees), and has been approved to build “Provincial Enterprise Research Institute” of Zhejing province and “High-tech R&D Center” of Jiaxing. In the field of CIGS solar cells, the R&D team achieved the third conversion efficiency in the world.

關於「秀洲高新區」About the “Xiuzhou National High-tech Zone”

嘉興秀洲高新技術產業開發區（簡稱秀洲高新區）位於嘉興市西側，2006年被批准為省級開發區。2015年9月，國務院正式同意秀洲高新區升級為國家高新技術產業開發區。經過十多年的發展，秀洲高新區已成為嘉興市經濟轉型升級的重要基地。2017 年 8 月，首次參與國家高新區排名的秀洲高新區，綜合排名進入全國前二分之一佇列，排名居全國所有新升級的國家高新區首位。

The “Xiuzhou National High-tech Zone” (the Zone) is located at the west of the Jiaxing prefecture of Zhejiang province, China, which was approved to be a province-level development zone in 2006. In Sep 2015, the State Council approved the Zone to be upgraded to a National High-tech Industrial Development Zone. After the developing for more than 10 years, the Zone now becomes an important base for  economic transformation and upgrade  in Jiaxing. In Aug 2017, the Zone joined the National high-tech zone ranking in China for the first time, and its overall ranking  entered the first half nationally,  and is the highest rank among all newly upgraded national high-tech zones.
