Solar collectors are special kinds of heat exchangers that transform solar radiation energy to internal energy of the transport medium. The major component of any solar system is the solar collector.
These include water heating, space heating and cooling, refrigeration, industrial process heat, desalination, thermal power systems, solar furnaces and chemistry applications. It should be noted that the applications of solar energy collectors are not limited to the above areas.
An energy efficient solar collector should absorb incident solar radiation, convert it to thermal energy and deliver the thermal energy to a heat transfer medium with minimum losses at each step. It is possible to use several different design principles and physical mechanisms in order to create a selective solar absorbing surface.
The two major types of collectors, i.e. flat-plate and concentrating are examined separately. The basic parameter to consider is the collector thermal efficiency. This is defined as the ratio of the useful energy delivered to the energy incident on the collector aperture. The incident solar flux consists of direct and diffuse radiation.
Solar collectors form the core of a solar thermal system. As their name suggests, they collect the sun's rays. This is then followed by conversion into usable heat, which can then be used to heat domestic hot water or as a central heating backup in the home.
They do not include incidence angle effects, which vary throughout the year, heat exchanger effects, probabilities of occurrence of Ti, Ta, solar irradiation, system heat loss, or control strategies. Final selection requires determining the long-term energy output of a collector as well as performance cost-effectiveness studies.
Glass remains the most frequently used cover material because it transmits as much as 90% of the incoming short-wave solar radiation, while, particularly for glass with low iron content, little of the long wave thermal radiation emitted by the absorber is transmitted out of the collector.

Solar cells hold the key for turning sunshine into into electricity we can use to power our homes each and every day. They make it possible to tap into the sun's vast, renewable energy. Solar technology has advanced rapidly over the years, and now, solar cells are at the forefront of creating clean, sustainable energy from sunlight.
Due to their special structure and the materials in solar cells, the electrons are only allowed to move in a single direction. The electronic structure of the materials is very important for the process to work, and often silicon incorporating small amounts of boron or phosphorus is used in different layers.
The theory of solar cells explains the process by which light energy in photons is converted into electric current when the photons strike a suitable semiconductor device.
The operation of solar cells is intimately related to two kinds of particles, electrons and holes, known as the charge carriers of semiconductors. For the case of electrons, this does not come as a surprise since general knowledge identifies an electric (charge) current to the continuous flow of electrons.
Each wafer thus produced is hence a circular disc. To make the resulting solar cell function properly, its active area must be square so the rounded edges of the wafer get sawn off so the wafers can be packed together as closely as possible during bulk processing. The chamfered corners are left.
However, it is required for many semiconductor devices that the passivation layer allows the flow of majority carriers. This is the case for solar cells, in which electrons need to be able to exit the n side of the cell and holes need to be able to exit the p side (this will be thoroughly analyzed in Section 3.4).
