Abstract: The experiment compared and tested which type of incandescent lamp is more effective to provide the greatest efficiency on the tested solar cells. It was believed that halogen lamps will be the more effective light source and be more efficient due to less energy lost due to heat. Halogen lamps are a more efficient light source to use than tungsten lamps due to the higher efficiency percentages than their tungsten companions on solar cells. It tested the various power outputs through varying resistances and the efficiency was calculated to compare which type of lamp is most effective. The Halogen lamps had efficiency ratings of 1.578% (silicon cell at 600 Ω), 0.0128% (organic cell at 600 Ω) compared to tungsten’s 0.452% (silicon cell at 1000 Ω), 0.00368% (organic cell 1500 Ω) which is a difference of 1.126% (silicon cell) and 0.00912% (organic cell). The most likely reason for these results may be due to the halogen lamp having a similar preferred wavelength of light emitted to the design of the solar cells than tungsten.

Pure tungsten has a light grey and whitish colour which is quite a soft metal which can be cut easily by a simple saw and its ductile enough to be able to be manipulated into different shapes and into a wire. Tungsten also has the highest melting point of all the metals thus it is able to be used as filaments found within incandescent bulb as it would not melt. Tungsten has a melting point of approximately 3695K and has certain characteristics due to temperature such as voltage, current, wattage and efficiency within Forsythe and Worthing (1925) Tungsten is regularly used within filaments due to this property and is able to be heated so that it is able to release photons of light within light
