Review of solar photovoltaic cooling systems technologies with environmental and economical assessment. Tareq Salameh, ... Abdul Ghani Olabi, in Journal of Cleaner Production, 2021. 2.1 Crystalline silicon solar cells (first generation). At the heart of PV systems, a solar cell is a key component for bringing down area- or scale-related costs and increasing the overall performance.
To make a silicon solar cell, blocks of crystalline silicon are cut into very thin wafers. The wafer is processed on both sides to separate the electrical charges and form a diode, a device that allows current to flow in only one direction. The diode is sandwiched between metal contacts to let the electrical current easily flow out of the cell.
Working Principle: The solar cell working principle involves converting light energy into electrical energy by separating light-induced charge carriers within a semiconductor. Role of Semiconductors: Semiconductors like silicon are crucial because their properties can be modified to create free electrons or holes that carry electric current.
A silicon photovoltaic (PV) cell converts the energy of sunlight directly into electricity—a process called the photovoltaic effect—by using a thin layer or wafer of silicon that has been doped to create a PN junction. The depth and distribution of impurity atoms can be controlled very precisely during the doping process.
Silicon solar cells are the most broadly utilized of all solar cell due to their high photo-conversion efficiency even as single junction photovoltaic devices. Besides, the high relative abundance of silicon drives their preference in the PV landscape.
Instead, it is free to move inside the silicon structure. A solar cell consists of a layer of p-type silicon placed next to a layer of n-type silicon (Fig. 1). In the n-type layer, there is an excess of electrons, and in the p-type layer, there is an excess of positively charged holes (which are vacancies due to the lack of valence electrons).
Solar cell, any device that directly converts the energy of light into electrical energy through the photovoltaic effect. The majority of solar cells are fabricated from silicon—with increasing efficiency and lowering cost as the materials range from amorphous to polycrystalline to crystalline silicon forms.

Photovoltaic cells are made of special materials called semiconductors such as silicon. An atom of silicon has 14 electrons, arranged in three different shells. The outer shell has 4 electrons. Therefore a silicon atom will always look for ways to fill up its last shell, and to do this, it will share electrons with four nearby atoms.
For silicon solar cells, a more realistic efficiency under one sun operation is about 29% 2. The maximum efficiency measured for a silicon solar cell is currently 26.7% under AM1.5G. The difference between the high theoretical efficiencies and the efficiencies measured from terrestrial solar cells is due mainly to two factors. The first is that the theoretical maximum efficiency …
A solar cell is made of two types of semiconductors, called p-type and n-type silicon. The p-type silicon is produced by adding atoms—such as boron or gallium—that have one less electron in their outer energy level than does silicon. Because boron has one less electron than is required to form the bonds with the surrounding silicon atoms, an electron vacancy or "hole" is created.
Planar perovskite solar cells (PSCs) can be made in either a regular n–i–p structure or an inverted p–i–n structure (see Fig. 1 for the meaning of n–i–p and p–i–n as regular and inverted architecture), They are made from either organic–inorganic hybrid semiconducting materials or a complete inorganic material typically made of triple cation semiconductors that …
