Scientists boost solar energy conversion efficiency
Scientists at RMIT University are attempting to boost the efficiency of solar energy conversion technology with an improved type of solar cell.
The cells, known as semiconductor quantum dot sensitised solar cells, are new-generation solar cells which offer the potential to exceed the conventional theoretical maximum solar energy conversion efficiency of 30%.
By modifying the size and shape of the quantum dots, the maximum efficiency will be boosted considerably.
Associate Professor Yasuhiro Tachibana, from the School of Aerospace, Mechanical and Manufacturing Engineering, said the research sought to influence aspects of the photo-induced electron transfer reaction which occurs inside each solar cell using “time-resolved laser spectroscopies”.
The work to date has been promising, he said.
“Semiconductor quantum dots are one of the most attractive nanomaterials for solar cell technology,” he said.
“The key research is to identify the underlying parameters which control the electron transfer reactions at the nanomaterial interface, determining the solar energy conversion efficiency.”
The research project is being supported by the Japan Science and Technology Agency (JST), Japan.
