Perovskite photovoltaic

A review of the patent landscape

This report will enable you to identify the leading organisations filing perovskite device, process, and materials patents, when they filed, what patents have been granted, what are the main technology areas where filings have occurred, and which industry sectors are the most active.

Those companies that file early patents will clearly have a competitive advantage - understanding what patents are being filed will enable companies to avoid competition

Perovskite solar cell developments are progressing fast

Since 2010 there has been significant and rapid progress in the development of perovskite photovoltaic technologies. Companies like Oxford Photovoltiacs and Greatcell (nee Dyesol) are moving ever closer towards early commercialisation of production ready perovskite solar cells.

Perovskite photovoltaics may be an emerging technology but in terms of power conversion efficiency perovskite it has already achieved more that 20% for cells and are seen as a serious competitor to the industry standard silicon based solar cells, given the many companies and research institutions increasing their investments in this technology there is a confident expectation that efficiencies could reach 30% in the not too distance future.

Early perovskite solar cells to be commercialised will be built on glass substrates, the long-term ambitions of the industry will see perovskite devices built on flexible plastic substrates.

Given their high efficiencies made possible with perovskite solar cells it is easy to envisage them being used in many conventional applications like building integrated pv, portable charging and energy harvesting.

Recent research published demonstrated that it is now possible to fabricate perovskite devices on paper substrates - leading to the possibility of designing and manufacturing clothes that can power wearable devices.

What is clear is perovskite solar cells will enter the market within the next few years, and have a viable and long-term commercial future.


Perovskite patent filings are growing rapidly

Since 2010 more than 2,000 patents relating to perovskite technologies covering over 1,200 patent families have been filed by over 490 academic and commercial assignees.

Filings from Chinese academics have grown in recent years, although these are largely from academics who mainly hold a single patent - what may be unexpected is more than 34 Chinese academics hold five or more patents.

The number of Chinese patents may be large but as can be seen Chinese patents are largely filed and published within China - this is in contrast to other countries where there is a greater emphasis on publishing beyond the priority country

The number of patents being granted is growing, with academia accounting for over 60% of these early granted patents.

Understanding and tracking perovskite technology is important

Currently, technology development is focused on improving the operational lifetimes, device and module efficiencies, developing new device architectures, synthesising new materials, developing new deposition techniques, developing manufacturing processes and applications.

In order to gain competitive advantage companies and research institutions are actively filing patents as they seek to secure IP space they own and can commercialise.

The rapid technology progress means there is an increasing number of patent filings. Understanding this technology and commercial progress can be achieved with a review of the patent landscape.
