Solar Cell Photosynthesis Essay

very strict. The exact location that the infrared thermometer will capture the solar cell temperature is marked.

HYPOTHESIS

The hypothesis of this experiment is that if a solar cell is exposed to increased ambient temperatures, then the power output of the solar cell will be decreased.

This hypothesis is based on the statement posted on the Civic Solar website that excessive heat can reduce the output of a solar cell.

PROCESS OF DATA COLLECTION

An increase in temperature applied to the solar cell produced a reduction in power output as predicted. The solar cell used in this experiment has a maximum voltage output of 9.5 volts with an open circuit. The coldest temperature achieved was 52° F on the solar cell with a recorded power output of 9.5

To demonstrate this, the detailed steps described in the design steps should be followed. While the specific tools and equipment used to conduct this experiment could vary slightly, it would be crucial that the tools and equipment be used in the same manner. For instance, if a single multimeter that can read both voltage and amperage is not available, one meter for each can be utilized. Also, a solar cell that can produce more or less power than the 6 Volts used in this experiment would work as well. However, the controlled variables must be followed precisely to produce the same outcome.

REPLICATION

When replicating this experiment, it is important that attention to the details be followed. The controlled variables such as light, solar cell and consistently taking the temperature readings from the same spot on the solar cell, are very important to the outcome. If these steps are followed, the outcome of data will be the same as in this experiment. If other experiments of this nature are conducted, and the outcome of the data is not repeatable, then the light source should be evaluated and the proper functionality of the solar cell should be tested.
