Working Principle of Photovoltaic Cells. A photovoltaic cell essentially consists of a large planar p–n junction, i.e., a region of contact between layers of n- and p-doped semiconductor material, where both layers are electrically contacted (see below). The junction extends over the entire active area of the device.

All PV cells have both positive and negative layers — it''s the interaction between the two layers that makes the photovoltaic effect work. What distinguishes an N-Type vs. P-Type solar cell is whether the dominant carrier of electricity is positive or negative. N-Type PV cells contain atoms with one more electron than silicon in the outer layer
Steps in Making a Solar Cell: The Solar Cell Fabrication Process. The making of a solar cell starts with picking crystalline silicon. This material is key in most commercial solar panels. The process of making a photovoltaic cell is a series of steps. These steps make sure the cell can turn sunlight into electricity well.
Solar cells grew out of the 1839 discovery of the photovoltaic effect by French physicist A. E. Becquerel. However, it was not until 1883 that the first solar cell was built by Charles Fritts, who coated the semiconductor selenium with an extremely thin layer of gold...
Fundamentals of Solar Cell Working Principle. To understand how solar cells work, we need to look at the photovoltaic effect. It''s the magic behind converting sunlight into electricity. Solar cells are complex but incredible. They transform sunlight into electrons to power everything we use.

Comparison of the three phases have shown that anatase and rutile have the same photocurrent voltage response. On contrary, short-circuit current of anatase based solar cell is greater compared to the rutile based solar cell. The reason for this variation is that rutile has smaller surface area per unit volume [11]. In contrast, due to higher ...
