Single crystalline silicon is usually grown as a large cylindrical ingot producing circular or semi-square solar cells. The semi-square cell started out circular but has had the edges cut off so that a number of cells can be more efficiently packed into a rectangular module.
While individual solar cells can be connected within a single PV panel, solar photovoltaic panels can be connected in series and/or parallel to form an array, which increases the total potential power output for a given solar application as compared to a single panel. What is the connection between solar cells?
It is rarely used, except for special applications. The main alternative to crystalline silicon for solar cells is some form of thin film. From a manufacturing point of view, these are attractive because they can be produced using cheap techniques such as vapour deposition or even printing.
Solar panels in a single photovoltaic array are connected in the same way that PV cells are connected in a single panel. The panels in an array can be linked in series, parallel, or a combination of the two, although in most cases, a series connection is selected to enhance the output voltage.
The majority of silicon solar cells are fabricated from silicon wafers, which may be either single-crystalline or multi-crystalline. Single-crystalline wafers typically have better material parameters but are also more expensive. Crystalline silicon has an ordered crystal structure, with each atom ideally lying in a pre-determined position.
Single crystal solar cells are often 15.6 × 15.6 cm 2, giving a total current of almost 9 – 10A from a module. The table below shows the output of typical modules at STC. I MP and I SC do not change that much but V MP and V OC scale with the number of cells in the module.
