Light shining on solar cells

Fundamentals of Solar Cells and Light-Emitting Diodes

Light shining on a solar cell produces both electric current and bias voltage that generate electric power. This process requires, first, the generation of electron and hole carriers by the absorption of incident photons. Second, the collection of these carriers by the

Solar Light Energy: A Photovoltaic Cell | SpringerLink

A solar cell can produce up to 2 W of energy. When load current is zero, its voltage becomes maximum and is known as open-circuit voltage V oc.When load current increases, short circuit current I sc is reached, and voltage becomes zero. Power from a solar cell shows a bell-type behavior between these two extremes of zero power.

6 FAQs about [Light shining on solar cells]

How does a solar cell work?

The light enters the emitter first. The emitter is usually thin to keep the depletion region near where the light is strongly absorbed and the base is usually made thick enough to absorb most of the light. The basic steps in the operation of a solar cell are: the dissipation of power in the load and in parasitic resistances.

How does temperature affect a solar cell?

The short circuit current (Isc) increases with temperature, since the bandgap energy (Eg) decreases and more photons have enough energy to create e-h pairs. However, this is a small effect. For silicon The main effect of increasing temperature for silicon solar cells is a reduction in Voc, the fill factor and hence the cell output.

What causes a shunt resistance in a solar cell circuit?

Parasitic series and shunt resistances in a solar cell circuit. The major contributors to the series resistance (Rs) are the bulk resistance of the semiconductor material, the metallic contacts and interconnections, carrier transport through the top diffused layer, and contact resistance between the metallic contacts and the semiconductor.

How much sunlight can a solar cell use?

Maximum use can only be made of incoming sunlight if the bandgap is in the range 1.0–1.6 eV. This effect alone acts to limit the maximum achievable efficiency of solar cells to 44% (Shockley & Queisser, 1961). The bandgap of silicon, at 1.1 eV, is close to optimum, while that of gallium arsenide, at 1.4 eV, is even better, in principle.
