Photovoltaic, Thin Film, Dye-sensitized (DSSC)
Photovoltaic, Thin Film, Dye-sensitized (DSSC)
Techniques for creating DSSC are very simple and the materials are very low cost, but the conversion efficiency is also very low at between 5% and 10%.

This technique was invented in 1991 by Michael Grätzel and the solar cell is alternatively known as the Grätzel cell.

They have the characteristic of being semi-transparent, flexible, and are very durable. They also function comparatively better than other PV technologies in low light levels and indirect light. Because they are so inexpensive to produce they have one of the lowest price/performance ratios and are therefore most competitive with conventional energy in terms of cost per KWh despite their lower conversion efficiency.
