Solar Energy Control by Nano-optical Methods
At Zewail City of Science and Technology, Professor Salah Obayya and his team have developed novel nano-optical techniques with the aid of computer-based designs to significantly increase the efficiency of solar cells. It was shown in some of the team's recent publications that the superb light absorption of plasmonics, a type of unique surface waves, and the finely-engineered nano-antennas, a structure on the scale of a billionth of a meter, can provide the capability for focusing and confining the sun’s light, offering as much as 33% higher efficiency than conventional cells. These important findings were recently published in the IEEE Journal of Quantum Electronics and in IEE/IET Optoelectronics.
The Center for Nanotechnology at ZewailCity is near to complete functionality, and this facility, directed by Dr. Sherif Sedky, will enable the construction of new prototypes and the testing of various designs. Dr. Obayya and his team are continuing the R&D in this area of alternative energy, which is critical to Egypt’s needs and to the creation of a green society.
Zewail City is a non-profit organization. It is dedicated to advancing education, research and economic development. The city is governed by the supreme advisory board, which includes five Nobel laureates, and with a special law that grants the city its independence.
