the ability to print solar cells

Solterra Renewable Energy Technologies is on a mission to lower the cost of solar cells by introducing thin film quantum dot solar cells, which supposedly can cut the production costs of solar cells in half. Quantum Dot PV Solar Cells is an advanced manufacturing process which not only lowers cost, but increases solar cell efficiency by allowing the solar cell to capture a broader spectrum of light. The manufacturing process of quantum dot PV solar cells is similar to low-cost screen printing or the way inkjet printers work. The ability to print solar cells onto inexpensive substrates is the key to Solterra’s patented manufacturing process, which is the key reason they are able to print the cost per watt down significantly.

Don’t get excited yet, this company is far from developing product for the mass public and has no efficiency data to backup the expected results of their product line. Although it will be an interesting solar technology to follow since printable solar cells can change solar power products overnight. What do you think about the ability to print solar cells onto virtually any substrate? What will quantum dot solar cells do to solar technology and most importantly the consumer?
