A solar cell (also known as a photovoltaic cell or PV cell) is defined as an electrical device that converts light energy into electrical energy through the photovoltaic effect. The first one is made using Matlab/simuling. Concepts are described for measuring the basic characteristics of solar cells and their dependencies on light intensity, temperature and light spectra. SOLAR CELLS By Adegbenro Ayodeji A Thesis submitted to The Faculty of Engineering at Cairo University and University of Kassel in Partial Fulfilment of the Requirements for the Degree of Master of Science in RENEWABLE ENERGY AND ENERGY EFFICIENCY Faculty of Engineering University of Kassel, Kassel, Germany Cairo University, Giza, Egypt June 2016. Describe function and deliverables of PV characterization techniques measuring . It is a form of photoelectric cell, defined as a device whose electrical characteristics, such as current, voltage, or resistance, vary when exposed to light. 0000000744 00000 n If your global solar cell was not very uniform (rather likely for many solar cell types), your local solar cells may show wildly different behaviour. %PDF-1.4 %���� 0000005261 00000 n • Those can, claim: Solar energy is tenuous, un-dependable, and expensive beyond practicality. Background: A solar cell is a semiconductor PN junction diode as shown in figure 1. 2 Solar Cell Characteristics Apparatus. Normally no external bias is applied to the cell. Solar cells transform light energy into electric current. A. The basic characteristics of a solar cell are the short-circuit current (ISC), the open-circuit voltage (VOC), the fill factor (FF) and the solar energy conversion efficiency (η). Design of Silicon Cells. Temperature Effects on Cell Characteristics 5. Our website is made possible by displaying certain online content using javascript. Attention is paid to principle work with various kinds of load resistances, to the function of a pyranometer, of a sun simulator and to the measurement of the quantum efficiency of solar cells. Buonassisi (MIT) 2011 . 3-43 (2018), https://doi.org/10.1142/9781786344496_0001. Solar Cell Sensitivity 6. P N. Sunlight. The importance of concentrated sunlight for increasing η is shown. The solar cell characterizations covered in this chapter address the electrical power generating capabilities of the cell. 4 When experiment is performed in sun light: 1. 0000003124 00000 n Solar Cell Design Principles; 5.1. Connect the circuit as shown by dotted lines (Fig. endstream endobj 135 0 obj <. Temperature Effects on Solar Cells 7. Note down the observation of voltage and current in Table 1. A solar cell is a semiconductor PN junction diode as shown in figure 1. 0000001022 00000 n 0000003452 00000 n Describe basic classifications of solar cell characterization methods. Solar cells convert power of sunlight into electric power. xref Solar Cell Voltage – Current Characterization . 0000004789 00000 n 3. Select the voltmeter range to 4V, current meter range to 2.5mA and load resistance (R L) to 50Ω. 154 0 obj <>stream The word “photovoltaic” can be divided into two parts: “photo” and “voltaic.” The term “photo” comes from the Greek word for light. Important parameters such as fill factor, short circuit current, and open circuit voltage can be measured. Solar cell is the basic unit of solar energy generation system where electrical energy is extracted directly from light energy without any intermediate process. Behrang H. Hamadani and Brian Dougherty . Solar cells convert power of sunlight into electric power. Tolerable series and parallel resistances are introduced as an evaluation criterion for resistive losses in real solar cells. The power of sun is given in terms of the solar constant, the power spectrum and power losses in earth atmosphere expressed by the so-called air mass. The specific role of Rs and Rp is discussed in detail for the dependence of η on ISC. Equivalent circuit of a solar or photovoltaic cell The solar cell. A solar cell is a semiconductor PN junction diode, normally without an external bias, that provides electrical power to a load when illuminated (Figure 1). Usually written as I SC, the short-circuit current is shown on the IV curve below. 0000002429 00000 n 0000007161 00000 n 0000008915 00000 n Visit http://www.exploregate.com for more videos on this topic. %%EOF As an introduction, therefore, Chapter 1 is devoted to a brief characterization of sunlight and basic electric parameters of solar cells. �4�[{*c�ɯ^/��I��$��dg��VH�.�XE�_ �%��S7�U��(��}$j'�5�91i�v�ž�\�E���J��s���2ΰ�}�.h~�m�?��Q�c2���V�ű�h�d�C ���bȋ�l���@�_�������|&T�/�љ��I��k̜>� $� UK���� This apparatus allows students in introductory physics course to plot I-V characteristics of a solar cell by a simple experiment. After solar cell processing, the j–V characteristics of every cell are measured, with V oc, j sc and FF determining the conversion efficiency (Eq. 2) through patch chords.
