diagram this tutorial explores how electrons in fluorophores are excited
from the ground state into higher electronic energy states and the events that
occur as these excited molecules emit photons and fall back into lower energy
states. Fluorescence activity can be schematically described with the

in 1935 to describe absorption and emission of light |

Solar cell operation
solar cells convert light energy into electrical energy either indirectly by first converting it into heat, or through a direct process known as the photovoltaic effect. The most common types of solar cells are based on the
photovoltaic effect, which occurs when light falling on a two-layer semiconductor material produces a potential difference, or voltage, between the
two layers |
