Among the entire family of solar cells, amorphous silicon thin film solar cells are experiencing explosive growth due to their technical and application advantages. In 2007, the industry growth rate was approximately 120% and the average annual growth rate is expected to reach 100% over the next three years.
The industry had previously had doubts about amorphous silicon thin-film solar cells, the main reason being that their cell conversion efficiency is low (5-9%) and they degrade very quickly, with limited service. lifespan of 2 to 3 years. With the advancement of technology, the current lifespan of mainstream amorphous silicon thin film batteries is more than 10 years. This makes amorphous silicon thin-film batteries one of the most promising thin-film battery technologies today.
At presente, in the domestic market, the listed companies involved in amorphous silicon thin film batteries mainly include: Tuori Xinneng, Tianwei Baobian, Variety Show Co., Ltd. and Ganneng Co., Ltd. Due to the rapid expansion of demand in the amorphous silicon industry, simply by purchasing equipment and realizing the production of amorphous silicon thin film cells, we can of course also achieve strong growth brought about by the expansion of the industry, but in the long run we can only share reasonable profits from the manufacturing industry. At present, domestic thin film batteries such as Ganneng Co., Ltd. are in OEM mode, and what they get are manufacturing profits at the middle end of the industrial chain. . Once the industry reaches its size, industry profits will inevitably shift to major bottlenecks.strangulation of the industry. This is why we are more optimistic about accessory manufacturers and equipment suppliers who have mastered key technologies.
