The aircraft industry is experiencing considerable demand for various technologically advanced equipment. The inclination curve of air travel is continuously climbing across geographies forcing the manufacturers of aircraft to provide an increased number of aircrafts such as fixed-wing and rotary-wing. The commercial air passenger is expected to maintain a continuous growth over the years, irrespective of numerous challenges faced by the commercial airlines such as aviation fuel price, and other monetary changes in various countries. However, these challenges are succeeded by the growth of several passengers across the world. In the aviation sector across the globe, the quest for advanced technology, robust systems, and rugged products are ever rising. The technological advancements in the field of aircraft are positively accepted by the developed countries as well as developing regions. The procurement of technologically advanced aircraft has bolstered over the years, flourishing the aircraft component manufacturing market.

电池片十年走过5 代技术，设备升级推动产业化：光伏电池始于1953年，在经历了一百多年逐渐走向产业化发电，尤其近十年全球光伏装机迅速扩大，装机量由2010 年16.83gw 提升至110gw 左右。光伏电池片发展本质是技术驱动降本提效，早期铝背场技术市场一枝独秀，后来转化效率更高的PERC 电池迅速崛起，到目前PERC+、TOPCon、HIT 等各种高效电池技术百家争鸣。新型电池片技术的产业化往往需要关键设备工艺的突破和国产化来推动，展望未来光伏电池技术更迭，率先实现设备突破和国产化的设备厂商有望充分受益。
