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.
CONCLUSION In this work, we pursue our studies of the one diode and two diode models to represent the solar cell assemblies. Simulation is carried out on MATLAB/ SIMULINK. We observe the importance of the ideality factor in our studies. Ideality factor for single solar cell is 1 where as for two solar cell is 2 i.e. 1˂α˂2.
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.
The record-level single-junction energy yield was calculated at 717 kWh/m 2 for the world record GaAs solar cell (STC efficiency 28.8%). Energy yield is primarily determined by the amount of sunlight available, with some noticeable influence from temperature and humidity.
At the maximum efficiency, the top cell absorbs 501.36 W/m 2 from the total 1,000.37 W/m 2 of sunlight power. Therefore, the incoming power is almost equally shared between the two cells; however, the top cell loses 43.3% of its incoming power while the Si bottom cell misses 71.2% of the sunlight power that enters into it.
However, the optimum dopant density (n-type cell) very slightly increases ∼10 5 cm −3 as the Si thickness reduces to 100 μm. Thus, in all locations, the optimum solar cell is a lowly doped wafer. For more details and exact numbers see supplemental information.
