Perovskite Solar cells
Perovskite solar cells (PSCs) utilize a perovskite structured compound as the light-harvesting active layer. PSCs consist of a transparent electrode, electron transporting layer, perovskite layer, hole transporting layer, and metallic electrode. When light enters the perovskite layer, electrons and holes are generated and transported through the layers, producing a current. PSCs can be produced through solution deposition methods and have advantages like higher efficiency and lower cost compared to silicon solar cells, but have disadvantages like using costly gold electrodes and short lifespan.
Dye sensitized solar cells
Dye Sensitized Solar Cells (DSSCs) are a type of thin-film solar cell that converts visible light to electrical energy. A DSSC consists of five key components: a transparent conductive substrate, a photoanode made of titanium dioxide coated with dye molecules, an electrolyte, and a platinum cathode. When light is absorbed by the dye molecules, electrons are injected into the titanium dioxide and transported through the external circuit to be collected at the cathode, completing the circuit. DSSCs have advantages such as optimized performance at higher temperatures, an ecologically friendly design, and higher efficiencies than traditional silicon cells. However, they also have disadvantages like the use of expensive platinum and ruthenium in the
Q switching for giant pulses in laser
Q-switching is a technique used to produce high-power laser pulses. It involves preventing the laser from oscillating to allow the population inversion in the lasing medium to build up to a high level. Then, by suddenly allowing oscillation, all the stored energy is emitted in a single giant pulse with peak power much higher than during normal operation. The pulse duration is typically 10-7 to 10-8 seconds. Q-switching provides a means to drastically increase the laser power output through stimulated emission of a very large number of atoms in the active medium.
General adaptation syndrome (syle model)
The General Adaptation Syndrome model proposed by Hans Selye describes the body's three stage response to stress: 1) the alarm stage triggers the fight or flight response, 2) the resistance stage sees the body trying to adapt to the stressor through the release of hormones, 3) the exhaustion stage occurs if stress is prolonged, depleting all energy and increasing susceptibility to disease. The response depends on the intensity and individual perception of the stressor, with chronic stress having severe physical and emotional impacts including suppression of the immune system.
