Solar Cells Market Growth

Crystalline silicon solar cells will witness growth on account of high energy conversion efficiencies and enhanced delivery of power when compared to its available alternatives. Furthermore, continuous technological developments, abundant silicon availability and declining raw material cost will significantly influence the business scenario.

Photovoltaics Manufacturing, Polysilicon

Purity levels for solar cells do not have to be as high as in chip applications. Solar-grade purity is 99.999% (5N) as opposed to electronic-grade silicon purity of up to 99.9999999% (9N). There are three main categories of manufacturing processes, resulting in different purity levels:

The true carbon footprint of photovoltaic energy

The rising demand for energy and the push towards low-carbon energy sources leads to rapid growth of ground-based photovoltaic parks all over the world. This constitutes an important change in land use on a global scale and requires critical studies for a detailed understanding of the impact of solar parks on the ground below them.

About 90% of current solar PV deployment is based on crystalline silicon solar cells—a technology that has been commercial for decades and is still improving. This efficient, reliable technology could achieve the needed large-scale deployment without major technological advances, says Bulović.

Learning from nature: the increasing efficiency of organic

"For years, solar photovoltaic cells have suffered from problems with efficiency, durability and cost. Part of the problem is to do with silicon, the semiconductor material traditionally used to turn the sun's energy into electricity," says Stone.

Amorphous silicon solar panels are a powerful and emerging line of photovoltaic systems that differ from crystalline silicon cells in terms of their output, structure, and manufacture. The material costs are reduced since amorphous silicon only requires about 1% of the silicon that would have been used to produce a crystalline-silicon based solar cell.
