fill factor of solar cell

Additional cell parameters and relationships are used to more fully characterize a solar cell. An inverted bulk heterojunction perovskite-PCBM solar cell with a high fill factor of 0.82 and a power conversion efficiency of up to 16.0% was fabricated by a low-temperature two-step solution process. 1. The FF is defined as the ratio of the maximum power from the solar cell to the product of Voc and Isc. Refer article on solar cell … The expression was originally suggested for silicon solar cells that behave according to a single-diode model and, in addition to V oc , it requires an ideality factor as input. Parasitic series and shunt resistances in a solar cell circuit. If you are talking in parlance of a solar cell, I think, probably, the term that you are looking for is Fill Factor or FF. Fill Factor is the ration of the maximum actual rated power to the theoretical maximum power. Solar cell is a device used to convert light into electricity. In this study, the fill factor analysis method and the double-diode model of a solar cell was applied to analyze the e ect of J01, J02, Rs, and Rsh on the fill factor in details. Solar Cell Voltage-Current Characterization Author: California Scientific, Inc. Subject: solar cell measurement Keywords: solar-cell, measurement, I-V, fill-factor, SMU Created Date: 4/9/2009 2:17:22 PM Our high efficiency HJ c-Si solar cells are investigated from the standpoint of the effective minority carrier lifetime (τ e), and the impact of τ e on fill factor (FF) is discussed. FF can also be interpreted graphically as the ratio of the rectangular areas. Published by Elsevier Ltd. A perylene diimide-containing acceptor enables high fill factor in organic solar cells† Kui Ding , a Tong Shan , a Jinqiu Xu , a Mengyang Li , b Yan Wang , a Yi Zhang , a Ziyi Xie , a Zaifei Ma , b Feng Liu a and Hongliang Zhong * a Figure 6: Typical IV curve of a solar cell plotted using current density, highlighting the short-circuit current density (Jsc), open-circuit voltage (Voc), current and voltage at maximum power (JMP and VMP respectively), maximum power point (PMax), and fill factor (FF). By shifting the sunsVoc curve along the current density axis by J SC (1 sun) the pseudo illuminated curve and the virtually series resistance free pseudo fill factor pFF are obtained. If the fill factor is low (below 0.7), the cells are considered as lower grade. Herein, to improve the fill factor, three fluorine substituted materials were designed, synthesized and characterized. Energy Procedia 38 ( 2013 ) 297 – 304 1876-6102 © 2013 The Authors. The average power conversion efficiency of the perovskite solar cells prepared on NaCl-doped PEDOT:PSS is 17.1% with negligible hysteresis, compared favorably to the control devices (15.1%). AU - Holman, Zachary. Light intensity: Changing the light intensity incident on a solar cell changes all solar cell parameters, including the short-circuit current, the open-circuit voltage, the fill factor, the efficiency and the impact of series and shunt resistances.The light intensity on a solar cell is called the number of suns, where 1 sun corresponds to standard illumination at AM1.5, or 1 kW/m 2. APPRATUS REQUIRED: Solar cell mounted on the front panel in a metal box with connections brought out on terminals. dependence of the PV module. It can be made by organic and inorganic materials. Also shown are the cell short-circuit current (Isc) and open-circuit voltage (Voc) points, as well as the maximum power point (Vmp, Imp).
