Lifespan and Decomposition Effects of 1st and 3 rd Generation Silicon Solar Cell with respect to Environment and Health

— Utilization of solar photovoltaic is increasing dayby day to reduce dependence on the power grid. Decompositionof 1st and 3rd generation silicon solar cells not only depends uponthe plastic and other materials but also the hazardous elementmainly used as their character on the bases of which they arecategorized as 1st , 2nd and 3rd contemporaries solar cells. Theseingredient are mostly carcinogenic and some of them having lifespan of more than 100 years. After abjection of solar cells, theyremain in the soil for many years and cause serious problem toland environment and also responsible for causing carcinogenicdisease in human and other living beings. This paper exploresdecomposition rates of the chemical element mainly used in 1stand 3rd generation solar cells throughout the past years, possibleenvironmental and health effects by the hazardous elements usedin them typically silicon (atomic number 14) and focusing onpossible suggested solutions or alternatives.
