Polycrystalline silicon production of photovoltaic glass

What is a crystalline silicon PV cell?

The crystalline silicon PV cell is one of many silicon-based semiconductor devices. The PV cell is essentially a diode with a semiconductor structure (Figure 1), and in the early years of solar cell production, many technologies for crystalline silicon cells were proposed on the basis of silicon semiconductor devices.

How can crystalline silicon solar cells be produced?

Production technologies such as silver-paste screen printing and firing for contact formation are therefore needed to lower the cost and increase the volume of production for crystalline silicon solar cells.

What are crystalline silicon solar cells?

Crystalline silicon PV cells are the most popular solar cells on the market and also provide the highest energy conversion efficiencies of all commercial solar cells and modules. The structure of typical commercial crystalline-silicon PV cells is shown in Figure 1.

What are the efficiencies of crystalline silicon solar cells?

The efficiencies of typical commercial crystalline silicon solar cells with standard cell structures are in the range of 16–18% for monocrystalline substrates and 15–17% for polycrystalline substrates. The substrate thickness used in most standard crystalline cells is 160–240 μm.

How are monocrystalline solar cells made?

Monocrystalline solar cells are produced from pseudo-square silicon wafer substrates cut from column ingots grown by the Czochralski (CZ) process (see Figure 2). Polycrystalline cells, on the other hand, are made from square silicon substrates cut from polycrystalline ingots grown in quartz crucibles.

Can poly-Si thin-film solar cells be used on glass?

Solar Energy Materials and Solar Cells (2008) in press, doi:10.1016/j.solmat.2008.09.059. Poly-Si thin-film solar cells on glass feature the potential to reach single-junction efficiencies of 15% or even higher at low costs.
