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 anN-Type vs. P-Type solar cellis whether the dominant carrier of electricity is positive or negative. N-Type PV cellscontain atoms wit...
Learn what a photovoltaic cell is and how it converts sunlight into usable electricity in a solar PV installation.
PV solar panels work with one or more electric fields that force electrons freed by light absorption to flow in a certain direction. This flow of electrons is a current, and by placing metal contacts on the top and bottom of the PV cell, we can draw that current off for external use. ...
Just like the cells in a battery, the cells in a solar panel are designed to generate electricity; but where a battery's cells make electricity from chemicals, a solar panel's cells generate power by capturing sunlight instead. They are sometimes called photovoltaic (PV) cells because they ...
An important feature of PV cells is that the voltage of the cell does not depend on its size, and remains fairly constant with changing light intensity. However, the current in a device is almost directly proportional to light intensity and size. When people want to compare different sized ce...
Curious about how the solar cells used in PV panels convert sunlight into electricity? Learn all about monocrystalline, polycrystalline & thin film solar cells here.
Monofacial vs bifacial solar PV modules At cell structure level, traditional monofacial cell back surface is an aluminum back surface field, which blocks light absorption on the back. Optimizing bifacial cells requires adopting a bifacial alkali texturization process to guarantee the same light-trapp...

creating the first practical solar cell — now 6% efficient. This discovery led to solar cells capable of powering electrical equipment. In 1956, Western Electric began selling commercial licenses for its silicon PV technologies, but the prohibitive costs of silicon solar cells keep them from widespr...
So far, we've been talking about photovoltaic (PV) solar because it's what many homes and businesses use to generate free, clean electricity. But other types of solar technology exist—the two most common are solar hot water and concentrated solar power. Solar hot water Solar hot water sy...
