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

Abstract

— Utilization of solar photovoltaic is increasing day
by day to reduce dependence on the power grid. Decomposition
of 1st and 3rd generation silicon solar cells not only depends upon
the plastic and other materials but also the hazardous element
mainly used as their character on the bases of which they are
categorized as 1st , 2nd and 3rd contemporaries solar cells. These
ingredient are mostly carcinogenic and some of them having life
span of more than 100 years. After abjection of solar cells, they
remain in the soil for many years and cause serious problem to
land environment and also responsible for causing carcinogenic
disease in human and other living beings. This paper explores
decomposition rates of the chemical element mainly used in 1st
and 3rd generation solar cells throughout the past years, possible
environmental and health effects by the hazardous elements used
in them typically silicon (atomic number 14) and focusing on
possible suggested solutions or alternatives.
