The power industry continues to be a hotbed of innovation, with activity driven by growth in renewable energy and initiatives for zero carbon emissions, and growing importance of technologies such as battery energy storage systems (BESS), and electrolyser/fuel cell energy. In the last three years alone, there have been over 439,000 patents filed and granted in the power industry, according to GlobalData’s report on Innovation in Power: PV film manufacturing.

According to GlobalData’s Technology Foresights, which uses over 83,000 patents to analyse innovation intensity for the power industry, there are 90+ innovation areas that will shape the future of the industry.

PV film manufacturing is a key innovation area in power

Photovoltaic (PV) film is manufactured by depositing a thin layer of semiconductor on a supporting material such as glass, stainless steel or polyimide through chemical vapour deposition process.

GlobalData’s analysis also uncovers the companies at the forefront of each innovation area and assesses the potential reach and impact of their patenting activity across different applications and geographies.  According to GlobalData, there are 20+ companies, spanning technology vendors, established power companies, and up-and-coming start-ups engaged in the development and application of PV film manufacturing.

Key players in PV film manufacturing – a disruptive innovation in the power industry

 ‘Application diversity’ measures the number of different applications identified for each relevant patent and broadly splits companies into either ‘niche’ or ‘diversified’ innovators.

‘Geographic reach’ refers to the number of different countries each relevant patent is registered in and reflects the breadth of geographic application intended, ranging from ‘global’ to ‘local’.

LG has filed the largest number of patents. The company’s solar arm LG Solar Business Solutions delivered solar panels products such as NeON® H series panels, NeON® 2 series panels and NeON® R series panels. Dow , an American chemical company, also filed the patents. The company offers ENGAGE™ PV Polyolefin Elastomers (POEs) product for PV encapsulant films that increases power generation, reliability and service life.

With regards to geographic reach of its patents, US-based 3M is a leading patent filer. The company provides 3M ™ Solar Encapsulant Films, which are fast cure encapsulant, designed to work with PV modules. The films protect against UV damage and weathering and allows broad band light transmission to solar cells. In terms of application diversity, Japanese multinational corporation Toray Industries filed the maximum patents. The company provides slat9type solar module production system for solar cells. It also manufactures high barrier disposition equipment for thin film PV cells.
