The device structure of a silicon solar cell is based on the concept of a p-n junction, for which dopant atoms such as phosphorus and boron are introduced into intrinsic silicon for preparing n- or p-type silicon, respectively. A simplified schematic cross-section of a commercial mono-crystalline silicon solar cell is shown in Fig. 2.
The crystalline silicon solar cell is first-generation technology and entered the world in 1954. Twenty-six years after crystalline silicon, the thin-film solar cell came into existence, which is second-generation technology. And the last, the third-generation solar cell, is still emerging technology and not fully commercialized.
An ideal solar cell has a direct band gap of 1.4 eV to absorb the maximum number of photons from the sun's radiation. Silicon solar cells, however, have an indirect band gap of 1.1 eV. With the world craving a new source of energy besides fossil fuels, silicon solar cells will play a much larger role in the future.
All silicon solar cells require extremely pure silicon. The manufacture of pure silicon is both expensive and energy intensive. The traditional method of production required 90 kWh of electricity for each kilogram of silicon. Newer methods have been able to reduce this to 15 kWh/kg.
Current global players are Solar Frontier and Global Solar Energy. Amorphous silicon (a-Si) solar cells use amorphous silicon as energy-absorbing material. We can deposit non-crystalline silicon on the glass to give rigidity or on the plastic to give flexibility.
Following are the different types of solar cells used in the solar panels: Amorphous silicon solar cells (a-Si). Biohybrid solar cell. Buried contact solar cell. Cadmium telluride solar cell (Cd Te). Concentrated PV Cell (CVP and HCVP). Copper Indium Gallium selenide solar cells (CI (G)S). Crystalline silicon solar cell (C-Si).
