摘要：This paper presents a performance study of silicon-based multi-junction (MJ) solar cell which is produced by Spectrolab is the most efficient solar cell in the world, with a record efficiency of over 40%. The I-V characteristics of solar cells were investigated for different environmental conditions (both at indoor and outdoor). Photovoltaic (PV) parameters like short circuit current (ISC), open circuit voltage (VOC), fill factor (FF) and efficiency (?) were evaluated for the fabricated cell. The fabricated cell provides I-V characteristics curve which shows that the maximum efficiency of the cell is obtained when the cell temperature is lower. It was also observed that, efficiencies of the cells are about 17% to 24% at indoor and 7% to 20% at outdoor and fill factors are 0.40 to 0.71. From the result, it can also be found that fill factor is directly affected by the values of the cells series and shunt resistance.
