Studies on Low Cost LED Based Solar Cell for Emergency Lighting

This paper describes some studies on low cost solar cell for generation of electrical common red coloured LED. The cost of LED based solar cell is relatively much lower as compare to commercially available photo-voltaic solar cell for small stand alone application become economically feasible. LED based solar cell can also help the environment by cutting electricity power generation and its associated greenhouse gas emission. Due to small size, durability, long operating lifetime, wavelength specificity, relatively cool emitting surfaces, and linear photon output with electrical input current waveband of LEDs (single color, nonphosphor coated) over solid-state light sources is much narrower used for generating electricity. Therefore, a LED based solar cell is proposed which is recent progress toward realizing fu based LED. Solid-state lighting using LEDs need drivers integrated in the design to convert existing voltages into the voltages necessary to control the LEDs. An overall discussion is focused in key ar with nano-scale devices such as nano-particles (0D), nano used to increase efficiency of over solid state lighting
