Creating a stable solar module device


KUANTAN: A Universiti Malaysia Pahang (UMP) research team has developed the “world’s first nanorod-based perovskite solar module” in collaboration with University of Rome Tor Vergatta, Italy.

The research work that produced high efficiency perovskite solar modules, a recently emerged cheap solar cell technology, also solved the key issue of stability in these devices.

UMP said in a statement that the research results had been published in ACS Nano, a journal of American Chemical Society which ranks second in the field of nanotechnology.

The team leader from UMP, Prof Dr Jose Rajan called their findings a significant milestone in the field of nanotechnology.

The professor of Physics and Materials Technology at the Faculty of Industrial Science & Technology (FIST) said although nanorods had been known for over 15 years, research had been limited only to laboratory scale and producing a large area-practical device was a significant challenge.

However, his team in collaboration with the Center of Hybrid and Organic Solar Energy (CHOSE) of the University of Rome Tor Vergatta, had solved the technology bottleneck.

Prof Thomas Brown, who led the research team of the Italian university, said this was the first time a perovskite solar module had shown long-term indoor stable performance.

He also said the results were promising for this recently emerged class of solar cell technology and that the use of nanorods, developed in UMP, had increased the performance and lifetime of these solar cells owing to their thermodynamically stable nature.

Brown termed the findings “a need-of-time” as perovskite solar cells, despite their high efficiency values, had been known to suffer from degradation.

Dr Azhar Fakharuddin, a key researcher in the work, said the results would open a new era of unconventional solar cell technology as perovskite solar modules could be made transparent for integrated building applications.

UMP vice-chancellor Prof Datuk Dr Daing Nasir Ibrahim called the findings a significant development in UMP’s research history and congratulated both teams working on the project.

“The findings reflect the true spirit of direct scientific collaboration and the hard work of both teams and also UMP’s vision to advance in cutting-edge scientific research,” he said in the statement.

UMP deputy vice-chancellor of research and innovation Prof Dr Mashitah Mohd Yusoff said UMP was also the first from Malaysia to publish its research in this emerging area as could be seen from the scientific databases Scopus and ISI web of knowledge.

She said the current report published in ACS Nano in July proved the high spirit of research among UMP researchers, not only at the national level but also the international scientific community.
