Solar Cells. How Does Solar Cell Output Vary with Incident Light Intensity? As the light got less intense (moved farther away) from the solar cell, the voltage clearly reduced. In our solar cell experiment, we were tasked with experimenting with solar panels and how they function. Experiment with solar power by building your own solar-powered robot or oven or by testing ways to speed up an existing solar car. Changing the light intensity incident on a solar cell changes all solar cell parameters, including the short-circuit current, the open-circuit voltage, the FF, the efficiency and the impact of series and … Solar Cell Experiment Introduction: Solar Cells convert light energy to electrical energy, so are transducers.

Designing of Embedded System for Removing of Dust on Solar Panel A solar cell experiment was performed using a commercial polycrystalline silicon solar cell with an active atea (10 cm 5 cm). Change the resistor value a little bit and note again current and voltage. In the first part of the lab we wanted to see how changing the intensity of light affected the amount of electricity produced by the solar cell. Theory of Operation of a Solar Cell Sunlight hits the solar cell – if the energy of the photon is high enough (≥band gap energy), it is absorbed on the P-side. A second part to the lab had us experiment with different colored filters to change the wavelength of the light, while intensity remained constant, and record the results on electricity generation the filters had. Nano Solar Cell-based PV System Design. Aim 1: To investigate any relationship present between the distance between a solar cell and a lamp, and the current output of the solar cell, at a fixed voltage. Required fields are marked *. Experiment with solar power by building your own solar-powered robot or oven or by testing ways to speed up an existing solar car. Described simple experiments with the solar cell from the toy kit and other cheap equipment are appropriate to demonstrate the existence of (near) infrared radiation as a part of the electromagnetic spectrum to which the solar cell is also sensitive. Of that amount, 1,386 watts fall on a A photovoltaic or solar cell will be exposed to sunlight at different angles to find which position will allow the greatest amount of sunlight to reach the cell.

Demand Response: Demanding Responsive Action Through Responsible Demands, Hook up the alligator clips attached to the voltage probe to the solar cell’s wires and plug the probe into the NXT, Open Labview and run two control experiments with no light source: one with the solar cell turned upside down, and one with the cell turned right side up, Run 4 tests to determine how intensity of the light affects voltage produced: One with the flashlight 0cm away from the cell, one 10cm away, one 30 cm away, and one 60 cm away. The four-junction solar cells fabricated by metal organic chemical vapor deposition (MOCVD) are selected as test samples in our experiment, as shown in Fig. Temperature. Save my name, email, and website in this browser for the next time I comment. Your experiment will measure the effect of changing light intensity on power output from the solar cell. Some of them are very complex and require special tools or knowledge. When printing this document, you may NOT modify it in any way. Experiment Examples To plot the I - V characteristic curve of a solar cell To observe the relationship of current, voltage and power in a solar cell, and to identify the maximum power point, the short circuit current, and the open circuit voltage To evaluate fill factor of the solar cell Solar Cells Experiment - Student Question Title * 1. Wireless Solar Charger: This project shows a wireless solar charger that can charge the mobile phones. Solar cells are an alternative method for generating electricity directly from sunlight. Multiply current and voltage for all values and find the maximum power. In our solar cell experiment, we were tasked with experimenting with solar panels and how they function. In our experiment, the solar cell and motor had V = 1.1 volts and I = 0.11 amps. In any conventional silicon-based solar cell, there is an absolute limit on overall efficiency, based partly on the fact that each photon of light can only knock loose a single electron, even if that photon carried twice the energy needed to do so. The Speed of Light: Explore Solar Energy with a Supercapacitor Car Motor. Reproduction of material from this website without written permission is strictly prohibited. How to make an anemometer (wind speed meter). The results show that our hypothesis was correct. Arrange the solar cells and components as shown in the diagram in Figure 2.

Solar cells are made of two thin pieces of silicon, the substance that makes up sand and the second In this experiment, we were asked to use a solar cell, a light, a ruler, and some colored gels to determine different aspects of light intensity. The most commonly known solar cell is configured as a large-area p-n junction made from silicon. These experiments are geared for children ages 5-10, but may be adapted for all ages. This sends the “holes” towards the N-side. Get Something for Nothing: Free Power from the Sun! The goal of this activity is for students to develop a model for the power production of a solar cell, including what variables influence power production. Experiments show dramatic increase in solar cell output. Get an average of the voltage produced, as recorded by LabView and Excel and graph the findings. Then record current and voltage. Specifically, we were asked to discover the relationship between the distance between the cell and a light source and light intensity, and also the color of light and how that effects intensity. In the second part of the investigation a determination will be made of how much of the sunlight that has reached the cell is converted into electric power. A plot of current and voltage is called an IV curve and is a widely used way of characterizing a solar cell. The results show that using any type of filter reduces the voltage produced by the solar cell.
