Series Connection Effect on the Current Shunt Measuring Technique for Large Area Multicrystalline Silicon Solar Cells

The series connection effect on the electrical performance of a large area multicrystalline Silicon solar cell (21 cm × 21 cm) with back contact technology has been considered in a desert area. Short circuit current, open circuit voltage and output power are the major electrical parameters normally characterise the solar cells.The current shunt measuring technique has been used to avoid the problems encountered with traditional measuring methods. Achieving the optimum electrical short circuit current has been investigated. For this reason, two similar cells have been connected in series and their short circuit current has been measured. Then, the short circuit currents of the three cells and four cells have been obtained as well. These different connections short circuit currents have been studied to determine the most suitable number of cells that compiles with the used shunt resistance value. Furthermore, the correlated open circuit voltages and output powers have been illustrated for all cases.
