October 23, 2015: LEDs solar and lasers will significantly impact human life in the 21st century, said Professor Puspendu Das, Department of Inorganic and Physical Chemistry, Indian Institute of Science, Bangalore, at The UN International Year of Light 2015 celebration event organized by The School of Physical Sciences of Periyar University.
Das said solar photovoltaic process mainly involving the conversion of sunlight into electric energy through different semiconductors. He said, with oil and petroleum resources drying up, solar energy, LEDs and laser will become the only clean energy alternatives to meet future generations energy demands.
LEDs are also being used to illuminate the world through various applications, and also capable of creating high resolution display screens for smartphones, computers and televisions.
Laser technology has made possible advancements in nonlinear optics, holography, precision cutting, welding and drilling, laser-guided defense equipment, and optical telecommunication and laser-based surgical appliances.
