Let's look at what the word polarity means. Polarity essentially means that the generator has positive charges on one side and negative charges on the other. The voltage difference allows electric currents to flow from one end of the wire to the other. You need a voltmeter or multimeter if you want to check the polarity of your solar panel.
Some of these covered characteristics pertain to the workings within the cell structure (e.g., charge carrier lifetimes) while the majority of the highlighted characteristics help establish the macro per-formance of the finished solar cell (e.g., spectral response, maximum power out-put).
Even when inside a building, a simple voltage reading will reveal the polarity of a solar panel. Put the red positive meter lead on one side and the black negative lead on the other. This measures across the terminals or wires of the solar panel. You must set the volt meter to read DC Volts.
You can also use a volt meter to measure the voltage. This determines the solar panel's polarity. Even when inside a building, a simple voltage reading will reveal the polarity of a solar panel. Put the red positive meter lead on one side and the black negative lead on the other. This measures across the terminals or wires of the solar panel.
Chapter 4. The working principle of all today solar cells is essentially the same. It is based on the photovoltaic effect. In general, the photovoltaic effect means the generation of a potential difference at the junction of two different materials in response to visible or other radiation. The basic processes behind the photovoltaic effect are:
