Thesis (Bachelor of Science in Electronics Engineering) -- University of Rizal System-Morong.

EXECUTIVE SUMMARY: The trend of technology is rapidly increasing and the need to RE-used rather than disposed the electronic waste. (E-WASTE) is beneficial to the environment and for the future of the society. By disposing electronic waste it produces toxic radiations which are dangerous to human health, but by reusing E-Waste it could sustain our electricity generation, by means of using the defective semiconductor devices collectively such as LEDs, Transistors, and Diodes. This defective semiconductor device used in wide range of electronics application such as appliances, gadgets, old computer monitors and etc. This study aimed to test the efficiency of the utilization of defective light emitting diodes (leds) as an alternative source of energy for electronics related devices which used the experimental research design. The researchers specifically demonstrate the performance of the different set up for electrical energy production out of Defective Semiconductor Devices as an Alternative Source of Energy in terms of three (3) different time of exposure set by the researchers between: 9:00 am - 10:00 am, 12:00 pm - 1:00 pm, and 3:00 pm -4:00 pm whereas the defective semiconductors panel to be exposed to sunlight. Test its efficiency in terms of measured electrical parameters; namely voltage produced, current, drawn and power rating with respect to time the device exposed to sunlight and the sunlight intensity or luminance. The findings and conclusion of the study were as follows: the use of locally available materials, and defective led's could sustain the development of quality research output, the 12:00 pm - 1:00 pm device exposure can produced the greatest amount of current on the same load, has the greatest amount of potential difference given in 398 pieces of LED's can generate the greatest amount of power, the number of LED's the type of semiconductor used, and the time the device exposed to sunlight has an effect to the voltage produced, current drawn and power rating, among semiconductor devices LED's are the cheapest, and has a wide range of application in electronics simulation and design. Also, this experimental research has proved that there is significant difference between the improvised solar panel using Defective LED's and the existing solar panel in the market. Proven the researchers improvised solar panel could produced a 19.58V, 40mA, and 783.2mW, being compared to the existing solar panel in the market could produced, 17.67 V and 1.13A. 19.96W. through further study, research and circuit simulation of series to parallel connection of defective LED's the researchers believe that in the future it is significant to improvise the solar panel using LED's or any semiconductor devices. The researchers therefore conclude that in mere future, using sunlight as its abundant source through enough research and knowledge, there is no need for a costly solar panel existing In the market for this E-Waste thing can improvised the solar panel, and can be generate about the same voltage. However, using knowledge in electronic circuit and more light emitting diodes (LED'S) connected in series-parallel can produce great amount of current and power by utilizing LED's and sun as its major sources.
