Towards improving the performance of solar photovoltaic energy system: A review

Performance of solar PV energy system is affected by many factors like solar radiation intensity, solar radiation geometry, temperature, wind speed and direction, relative humidity, dust, etc. Many researchers have been working on the effect of temperature on solar PV cell efficiency and have reported that increased cell temperature tends to reduce the efficiency of solar PV cell. Solar PV cell temperature also considerably deteriorates the mechanical properties of backsheet of solar PV panel. This paper reviews the various attempts to improve the performance of crystalline silicon solar photovoltaic (PV) system. Performance of a solar PV panel when exposed to hot and dry climate is different from performance of similar solar PV panel in cold climate. From solar beam radiation, light is a desired component whereas heat is not. Therefore many researchers have reported cooling techniques for Solar PV system. However, backsheet material of solar PV panel is one of the factors affecting the solar PV panel efficiency which is pulling the attention of many researchers for performance enhancement of Solar PV system. Solar PV cells using Perovskite material have emerged as one of next generation of photovoltaic technologies having capability of significant enhancement in solar cell efficiency.
