Solar Cell Experiment Introduction Solar Cells convert precipitate aught to electrical energy, so are transducers. Aim 1 To investigate any kindred present between the distance between a solar cell and a lamp, and the current appearput of the solar cell, at a fixed voltage. Aim 2 To investigate any relationship present between the power supplied to a bulb, and the current of a solar panel, at a fixed distance apart. When investigating a solar cell, there are several variables we could investigate. Below, I have analysed all the variables that could be investigated, and evaluated which one I willing investigate. When considering what variables of the light I could investigate, several things keep an eye on to mind. Variable 1 Light Light has different colours, and different glum lights are known to have different frequencies. This in turn would apparent motion the different coloured lights to emit different levels of power. We know that t his is the case because when compounding the two below radiation patterne, we can see that energy and frenquency are related. Wavelength x Frequency= Wave Speed Plancks Constant x frequency= talent The second formula states that frequency is directly proportional to energy. When rearranging the first formula to display frequency as the subject of the formula, and then substituting the measure for frenquency given (wave revive/wavelength) into the second formula, we get Planck s constant x wavespeed/wavelength= energy Using this formula, we can find out what kinds of light give out the most energy. As all light travels at the same speed (300,000 m/s), we know that the wavelength of the light will determine how much energy is given out from the light. The wavelength and frequency are directly related in light, because both multiplied must give a product of 300,000 m/s. We can gather by the formula that lights with a smaller wavelength will give out more energy, because when a smaller number is divided by the wavespeed and multiplied by the constant, a higher value for the
