In spite of this a typical 60 cell crystalline silicon solar module produced today contains up to 12 grams of lead.
Is there a substitute for silicone in a solar panel.
Another downside of silicon solar cells is their manufacturing requires expensive ultra high purity silicon.
Peskovite crystals which are naturally occuring look very promising as a cheaper alternative to silicon.
In the near term one solution advocated by prof mcgehee is the use of tandem solar cells which layer a perovskite on top of traditional silicon.
Commercial production of preskovite cells is yet.
Scientists at purdue university and the national renewable energy laboratory have discovered how electrons move in a.
Crystalline material could replace silicon to double efficiency of solar cells.
A key feature in evaluating alternative solar photovoltaic materials is cell efficiency.
As of today silicon is the cheapest material for the production of solar photovoltaic cells.
As a result there is a lot of interest in alternative photovoltaic materials.
