OverviewApplicationsHistoryDeclining costs and exponential growthTheoryEfficiencyMaterialsResearch in solar cells

A solar cell or photovoltaic cell (PV cell) is an electronic device that converts the energy of light directly into electricity by means of the photovoltaic effect. It is a form of photoelectric cell, a device whose electrical characteristics (such as current, voltage, or resistance) vary when it is exposed to light. Individual solar cell devices are often the electrical building blocks of photovoltaic modules, kn

What causes the photoelectric vs photovoltaic effect?

In the photovoltaic effect, electrons are knocked out of their atomic orbitals but remain within the material. What causes either the photoelectric or photovoltaic effect to take place upon photon absorption? Is it material dependent - i.e. metals follow the photoelectric effect whereas semiconductors follow the photovoltaic effect?

The photovoltaic effect

Voltage is generated in a solar cell by a process known as the "photovoltaic effect". The collection of light-generated carriers by the p-n junction causes a movement of electrons to the n-type side and holes to the p-type side of the junction. Under short circuit conditions, there is no build up of charge, as the carriers exit the device as
