The Photoelectric Effect and Its Applications to Solar Cells

The photoelectric effect occurs when electrically charged particles are released from or within a material when illuminated by light (or electromagnetic radiation). The light ejects electrons from the surface of the metal, and these electrons can cause an electric current to flow. The phenomenon was discovered in 1887 by the German physicist Heinrich Hertz.

Connecting Photovoltaic (PV) cells to form an array can cause difficulties when the characteristics of the cells are not synchronized.

6 FAQs about [Transverse resistance of photovoltaic cells]

Do photovoltaic solar cells have reverse bias?

Models to represent the behaviour of photovoltaic (PV) solar cells in reverse bias are reviewed, concluding with the proposal of a new model. This model comes from the study of avalanche mechanisms in PV solar cells, and counts on physically meaningful parameters.

What are the different types of reverse characteristics in PV solar cells?

It can also be applied to the different types of reverse characteristics found in PV solar cells: those dominated by avalanche mechanisms, and also those in which avalanche is not perceived because they are dominated by shunt resistance or because breakdown takes place out of a safe measurement range.

What is the equation for shunt resistance in photovoltaic cells?

In the case of B-type cells, the equation used by the authors is (3) I = I sc - I 0 ( exp V m V t - 1) - V R sh, where Rsh is shunt resistance. This classification between A and B types of reverse characteristic of photovoltaic cells is the same adopted in the international standards IEC-61215 and IEC-61646 .

Can a reverse characteristic be adapted to a PV cell?

It can be adapted to PV cells in which reverse characteristic is dominated by avalanche mechanisms, and also to those dominated by shunt resistance or with breakdown voltages far from a safe measurement range. A procedure to calculate model parameters based in piece-wise fitting is also proposed.

What causes shunt resistance in a solar cell?

Shunt resistance (R s h) is created due to leakage currents produced at the edge of the f-PSCs and the imperfection of the cell structure . This affects the parallel conductivity of a solar cell depending on the cell junction [, , , ]. As leakage currents increase, the efficiency of any solar cell decreases.
