However, not all innovations are equal and nor do they follow a constant upward trend. Instead, their evolution takes the form of an S-shaped curve that reflects their typical lifecycle from early emergence to accelerating adoption, before finally stabilizing and reaching maturity.
Identifying where a particular innovation is on this journey, especially those that are in the emerging and accelerating stages, is essential for understanding their current level of adoption and the likely future trajectory and impact they will have.
40+ innovations will shape the power industry
According to GlobalData’s Technology Foresights, which plots the S-curve for the power industry using innovation intensity models built on over 70,000 patents, there are 40+ innovation areas that will shape the future of the industry.
Within the emerging innovation stage, solar-powered charging stations, wind turbine performance monitoring, and renewable energy storage are disruptive technologies that are in the early stages of application and should be tracked closely. Foldable solar panels, solar thermal collectors, and geothermal collectors are some of the accelerating innovation areas, where adoption has been steadily increasing. Among maturing innovation areas are wave energy converters and solar cell protective films, which are now well established in the industry.

According to GlobalData, there are 80+ companies, spanning technology vendors, established power companies, and up-and-coming start-ups engaged in the development and application of solar cell protective films.
Key players in solar cell protective films – a disruptive innovation in the power industry
‘Application diversity’ measures the number of applications identified for each patent. It broadly splits companies into either ‘niche’ or ‘diversified’ innovators.
‘Geographic reach’ refers to the number of countries each patent is registered in. It reflects the breadth of geographic application intended, ranging from ‘global’ to ‘local’.

Eastman Chemical , Toray Industries , Kuraray, and Covestro are among the leading patent filers in solar cell protective films.
Covestro’s Polyurethane elastomers and solar coating solutions ensure reliable energy generation and long service life for solar panels. Covestro, in partnership with Massachusetts Institute of Technology, has developed a nano scale solar technology resulting in their anti-reflective coating service for solar glass, which is delivering a potential 3 percent solar efficiency gain in the field. The company completed construction of a new production facility in August 2023 for polyurethane dispersions (PUDs) in Shanghai, China.
Eastman Chemical produces Eastman Flexvue™ sputtered, conductive, reflective, and optically clear films for photovoltaic applications.
