Development of metal contacts with screen printing for n+ polysilicon/SiO𝑥 passivated silicon solar cells

The continued reliance on fossil fuels to satisfy the world energy demand is leading to climate change, accelerating the melting of polar ice shelf, and is dealing irreversible damage to the flora and fauna of earth, to name few of the adverse effects from fossil fuel utilisation. In addition to not being renewable, fossil-fuel resources are also limited. Therefore these resources cannot meet the energy demand at some point in future. The most plausible way is to utilise renewable sources of energy to meet the increasing demand of energy. The Sun, our closest star is the answer to this demand. Utilising the abundant solar radiation arriving at earth to generate electricity is a great way. A photovoltaic (PV) solar cell can achieve this by converting the incident sunlight directly to electricity.....
