Photovoltaics Boom: Innovations Surge 17-Fold in Three Decades π
A new report from the European Patent Office (EPO) and the European Innovation Council (EIC) reveals that photovoltaic innovations have skyrocketed, growing over 17-fold in the past three decades. π This surge is fueled by global pushes for sustainability, energy security, technological advancements, and falling production costs.
Key Trends in Photovoltaics
The report examines 340,000 inventions, including 70,000 international patent families, over five decades. Key areas include:
-
Photovoltaic materials (17% of inventions in 2020β2023)
-
Devices (48%)
-
Device management (10%)
-
Applications (25%), such as agrivoltaics and integration into buildings. π’
The number of inventions began rising in the late 1990s, peaking in 2020β2023. Device technologies led the charge, accounting for up to 78% of all patents from 1990 to 2023.
