Project Name : My Generation Generates Energy My Way
Theme Name : Natural Resource & their Conservation
Aims and Objective of the Study: To study the feasibility of LED lights panel as source of electricity and compare with solar panel.
Scientific Principle Involved: Solar panels are groups of P–N junctions, the P type Silicon is doped with Boron (creating free holes) and the N type silicon is doped with Phosphorus (creating free electrons). When they are joined then the electrons and the holes fuse at the junction (diffusion). When these electrons and holes move away they leave behind the opposite charges i.e. In the P type
negative (–) charge and in the N type positive (+) charges. Because of these charges a “in-build electric field” develops which stops the diffusion of the electrons and holes
Material Used:
40 red LED soldered on PCB Board as Panel 1
40 white LED soldered on PCB as Panel 2 and 100 white LED and 40 Red LED as Panel 3
100 multi coloured LED on PCB as Panel 4
9v solar panel – 1 no, Multimeter – 1 no, Used LED torch, Wires and Soldering kit
Working Investigation/Findings:
LED panel 1 (40 red LEDs): 10 LEDs were connected in series and 4 such columns were made and joined in parallel.
LED panel 2 (40 white LEDs): 10 LEDs were connected in series and 4 such columns were made and joined in parallel.
LED panel 3 (Red and White): white LEDs and 2 red LEDs were connected in series and 20 such columns were made and joined in parallel.
LED panel 4 (100 multi coloured LEDs): LEDs were connected in series and 10 such columns were made and joined in parallel.
Utility and further scope: LEDs do produce electricity but cannot replace the solar panel completely. Further studies and improvement in the design of LEDs may result in more absorption of light and better efficient LED SOLAR PANEL for personal use.
