In solar cells, depending on the material and technology used, the efficiency when it comes to converting different color bands into electricity is dependent on its spectral sensitivity. Some cells will have a greater efficiency with longer wavelengths while others prefer smaller wavelengths as shown in Figure 3. This is due to the size of the material''s band gap which determines how …
A solar cell is made of semiconducting materials, such as silicon, that have been fabricated into a p–n junction. Such junctions are made by doping one side of the device p-type and the other n-type, for example in the case of silicon by introducing small concentrations of boron or phosphorus respectively.
By far, the most prevalent bulk material for solar cells is crystalline silicon (c-Si), also known as "solar grade silicon". Bulk silicon is separated into multiple categories according to crystallinity and crystal size in the resulting ingot, ribbon or wafer. These cells are entirely based around the concept of a p–n junction.
Solar panels or PV modules are made by assembling solar cells into a frame that protects them from the environment. A typical PV module consists of a layer of protective glass, a layer of cells and a backsheet for insulation. In silicon PV module manufacturing, individual silicon solar cells are soldered together, typically in a 6×10 configuration.
The solar module consists of the silicon semiconductor surrounded by protective material in a metal frame. The protective material consists of an encapsulant of transparent silicon rubber or butyryl plastic (commonly used in automobile windshields) bonded around the cells, which are then embedded in ethylene vinyl acetate.
Crystalline silicon cells are made of silicon atoms connected to one another to form a crystal lattice. This lattice provides an organized structure that makes conversion of light into electricity more efficient. Solar cells made out of silicon currently provide a combination of high efficiency, low cost, and long lifetime.
Individual solar cell devices are often the electrical building blocks of photovoltaic modules, known colloquially as "solar panels". Almost all commercial PV cells consist of crystalline silicon, with a market share of 95%. Cadmium telluride thin-film solar cells account for the remainder.
