Girl Power: This Ghanaian Scientist Has Developed New Solar Cell Materials

This is an example of Girl Power, African Excellence and all the minority empowerment slogans you can think of, charley…

Ghanaian scientist, Selina Ama Saah has developed new materials that can be used to fabricate solar cells with improved efficiencies.

Get that… improved efficiencies…

The feat by Selina Ama Saah a lecturer at the Department of Chemical Sciences at the University of Energy and Natural Resources (UENR), Sunyani, could allow for solar cells to be manufactured locally, making it more affordable.

Here is another get that moment… but you got it already… huh?

“There’s the need to look for alternative solar cells which are efficient and affordable,” Selina Ama Saah, the scientist is quoted to have said.

She bumped into lead-based semiconductors during investigations into materials with properties similar to silicon for solar cell fabrication.

“Lead, we all know is toxic but it’s part of our environment because it’s the seventh most abundant heavy metal in the Earth’s crust.

“This research looked at alternative uses of lead not just being there and killing us but rather channelling it into energy. Lead-based semiconductors can be synthesized from lead complexes using simple spin coating techniques followed by annealing,” she said.

Selina has so far developed an absorber which is part of the active layer in polymer-based solar cells.

The next stage of the research, she says, will be blending the materials that have been made with polymers to make a complete solar cell.

“In the near future, we hope to see solar cells which are on plastic substrates that can be part of the device fabrication, so you need not put the silicon on top of the roof; it can be with you wherever you go because it will be like the sticker type,” she stressed.
