International Journal of Academic Engineering Research (IJAER)   Year: 2021 | Volume: 5 | Issue: 12 | Page No.: 1-6 Construction of a Laboratory Solar Cell Testing Equipment and Evaluation of Some Practical Construction Parameters on a Silicon Solar Cell Photo Conversion Nicholas F. de Souza, Henrique G. Pereira˛, Rubens Camarattaš Abstract: In this work, a solar cell test equipment was built with low-cost components. The equipment was evaluated by analyzing I-V curves of a monocrystalline silicon solar cell including the measurement of the short circuit current (Isc), open-circuit voltage (Voc), maximum power (Pmax), form factor (FF), and power conversion efficiency (PCE). Practical parameters for the construction equipment were investigated, namely the luminous intensity, the type of illumination, and the distance between the cell and the light source. The heating caused by the lamps was investigated on the short circuit current. The equipment proved to be robust and efficient to compare solar cells properties. However, it was observed that all the studied factors can change the measured photovoltaic parameters, and they must be fixed to obtain measurements capable of being compared.
