Solar cell - A solar cell, or photovoltaic cell, is a semiconductor device consisting of a large-area p-n junction diode, which in the presence of sunlight is capable of generating usable electrical energy. This conversion is called the photovoltaic effect.

Hybrid solar cell - Hybrid photovoltaic cells are a mix of two solar cell technologies. They comprise dye-sensitized titanium dioxide coated and sintered on a transparent semi-conducting oxide, and a p-type, polymeric conductor, which carries electrons from the counter electrode to the oxidized dye.

Polymer solar cell - Polymer solar cells produce electricity from sunlight. They are now durable and incorporated in many devices, for example, in small commercial calculators such as are given as gifts by accounting companies.

Hadley cell - The major driving force of atmospheric circulation in the tropical regions is solar heating. Because of the Earth's 23.
