# How the angle of a solar cell affects its output.

Extracts from this document...

Introduction

How the angle of a solar cell affects its output

Introduction:

The aim of the experiment is to investigate the relationship between the angles of a solar cell from its light source to the output of the solar cell. I will be able to see how the relationship changes (if there is a change) by the results which I record.

Apparatus:

The equipment which I will require to carry out my experiment are:

A solar cell

A multimeter

A light source

These are the things which I will need to carry out the experiment but I will also need equipment make sure the experiment is accurate, these are:

A clamp side with clamp, a piece of wood and blue tack, this will act as a stand on which my solar cell will be placed. The clamp stand and clamp will hold the piece of flat wood in a fixed position, to which the solar cell will be blue tacked into position, this will keep the cell firm and steady. A ruler will also be used to measure the distance of the solar cell from the light source. And a protractor will be used to measure the angle at which the solar cell is placed

Fair Test

I will make sure that the experiment is fair by making sure the light intensity is equal all the way through the experiment. I will do this by using the same light all the way through the experiment. I will also make sure that the light is at a equal distance away from the solar cell for every result, I will do this by measuring the distance (30cm) and keeping it constant. To get rid of any inaccuracies from other light sources (sun, class lights) I have chosen to carry out my experiment in a dark room where the only light that will be on will be the light that is shining onto the solar cell and the rest of the room will be dark. To make show that my results are accurate and so that I can achieve an accurate average result then I will take 3 readings of every angle that I measure. To make sure that my angle measurements are as accurate as possible I will attach a protractor onto a stand next to the stand which the solar cell is placed. The protractor will remain in that fixed position and the solar cell stand will move until it reaches the correct angle.

Conclusion

P=IV

I= current

V=voltage

So I will have to take two readings one for the amount of amps generated and another for the amount of current created. This will mean tat in total I will have to take 60 readings, because I am using the angle range of 0ºand 90º and I am taking readings every 10º, for every 10º I am taking 3 measurements for current a 3 for voltage. For every angle I shall turn the white light on and then read the measurements off the multimeter and turn the light off again (this will be repeated 3 times for every angle). I have decided to set the multimeter on the normal setting (maximum 2 volts) when measuring volts. But when I am measuring current I believe that the current will be small so I shall set the multimeter on milliamps when measuring the amps, I will have to stat this on my results table or my power output will be inaccurate. With the results that I get I shall record them into a table and draw a graph to plot the data. I shall then analysis the data and look for any patterns or results that I did not expect to occur.

This proves that black holes can be destroyed, and means that the black hole, if left 'starved' of matter would be depleted of energy. Einstein's equation, E=mc2, shows that energy is equal to mass, meaning the black hole will simply waste away and die in a catastrophic explosion.

I measured these at incremental distances from the light. For the light I used a standard desk task light that uses 60watts. I measured at 10cm increment distances from 50cm. All measurements were taken to the �1mm tolerance using a metre ruler secured to the table with tape so it couldn't move.

is the distance between the solar cell and the light source, and the effect upon the energy transferred to the solar cell when varying distances between the solar cell and light source. Distance direct affects the intensity of the light, and as distance increases, the light intensity decreases.

= ?D/d since D and d are constant. 2. If the distance apart d of the slits is diminished, keeping S fixed, the separation of the fringes increases. This follows from x= ?D/d 3. If the source slit S is widened the fringes gradually disappear. The slit S is then equivalent to a large number of narrow slits, each producing its own fringe system at different places.

This provides current, and the cells electric field provides the voltage. The more photons aimed at the cell the more electrons will be released; hence we have the commonly stated metric that the brighter the day, the more volts are produced by the solar panel.
