dc.description.abstract	The sicnence and engineering of solar cells has made impressive progress since it started in the last century. They are making their positive contribution to our climate change - environmental friendly alternative sources of energy on planet erath. However, there are still challenges for better utilization of the solar cells, and the challenges are linked to performance hindering factors like temperature, humidity, irradiation, wind speed and the like. In this project work, the effect of wind speed on the efficiency of the solar cells is reviewed. Wind speed and ambient temperature are related to each other and together they have effects on solar cells or photovoltaic systems. In total effect, ambient temperature and wind speed changes simultaneously. Significant performance improvement, on solar cells, is observed when, wind speed is high and ambient temperature is low. In brief, power is improved when wind speed is high and ambient temperature is low. In the review work, the study considers both PV panel and solar cells, as the effect is the same for both case as the panel is made of the solar cells. For crystalline PV cell the maximum power point decrease linearly with increases of ambient temperature and maximum power point increases as the result of mainly open circuit voltage and fill factor changes/increase. Consequently, the efficiency increases in wind speed. Yet, it has detailed device physics within the change in the efficiency. Assuming that all other weather parameters constant, wind speed changes the photovoltaic output power, if the wind direction is towards the front of the PV cell and the sun is at some position away in front of the cell. Thus, high wind speed causes to generate more electrical power and also increases the efficiency of solar cells. Keywords: Photovoltaic system, temperature, energy gap, parameters of solar cell maximum power point and wind speed.	en_US
