The department of laser engineering and optical electronics held a scientific lecture entitled (Techniques of solar / microcircuits).delivered by  prof Hadi Abdel Moneim Hamdani.

 The lecture included The severe shortage of fossil fuels and the damage caused by different environmental scientists have been to find alternative means of this fossil fuel and these alternatives were the solar energy is the most promising and the most available as the high cost of solar energy systems of solar panels, which represents one-third of the cost of the whole system and the price The solar system, which also reaches one-third of the total price of the system, and the price of storage systems (batteries) remains the third of the price. The rest of the system (voltite, regulator, wire and iron holder) represents 10% of the total price. The size of the solar radiation is limited to the solar cells, which are very small in size, thus reducing the silicon material used and reducing the cost. Here, the lecture deals with the possibility of directing the radiation from each lens on a microwave cell throughout the period of solar radiation through the use of a wave Radiation and slide of the center on the router to follow the sun disk and the entire process requires knowledge of the methods of fabrication of optical lens matrices after design in advance using optical track programs.
