A rethink of the building blocks for solar panels could help mass production

In the paper published inScientific Reports, Dr Ehsan Rezaee, a post-doctoral fellow of the Advanced Technology Institute (ATI) at the University of Surrey, explains his research:

"The objective is simply to produce solar cell building blocks out of perovskite ink. Whilst perovskite ink is not a new technology, current inks do not guarantee seamless transitions on an industrial scale, as the manufacturing process needs to be highly controlled and optimised.

"Our perovskite ink produces a fast and reproducible way to reliably fabricate these solar cell building blocks on a mass scale, paving the way for its use in commercial markets."

Perovskite solar cells are a low-cost, lightweight solution and can be built either rigid or flexible, with more possibilities to easily transport and install. The new study examines the foundation blocks of solar cells made of perovskite rather than the traditional silicon, as perovskite cells harvest light through the visible part of the solar spectrum, which has more energy.

Professor Ravi Silva, Director of the ATI at the University of Surrey, said:

"The University of Surrey has always believed in the potential of solar panels to be a critical research area which will, in time, allow us to move away from dangerous old energy sources.

"However, we must do more to improve the connection between research and production on a mass industry scale in order to see this as a future turning point, which is the purpose of our paper."

The University of Surrey is a leading research institution that focuses on sustainability for the benefit of society to deal with the many challenges of climate change. It is also committed to improving its own resource efficiency on its own estate in Guildford and being a sector leader. It has set a commitment to be carbon neutral by 2030. In April, it was ranked 55th in the world by the Times Higher Education (THE) University Impact Rankings which assesses more than 1,400 universities' performance against the United Nations' Sustainable Development Goals (SDGs).
