Factors influencing the efficiency of photovoltaic system

Long-time search for green energy as a replacement of the depleting conventional sources to the eternal power demand still remains as an unanswered question. But the steady growth in the contribution of solar energy towards the electrical power generation for the past three decades have persuaded many researchers to consider it as a viable option. However, the power harnessed from solar PV is low due to its less conversion efficiency. Therefore, it is necessary to perform some critical analysis on the factors improving the efficiency of the solar PV system. In this paper, an attempt is made in performing a detailed comprehensive review on the factors affecting the efficiency of solar cell. A detailed review is carried out on basic material used for solar cells, Maximum Power Point Tracking (MPPT) Techniques and the DC-DC converters used for power conversion.
