Perovskite
Halide perovskites are excellent solar energy harvesting materials, with lab-scale efficiencies already exceeding established thin-film technologies such as CdTe and CIGS. Perovskites offer a plethora of well-working compositions and variations, and their optoelectronic properties make it a very versatile semiconductor. This quality stems from simple processing, that enables low-temperature methods compatible with flexible substrates (e.g. plastic foil). Unlike crystalline silicon, perovskites perform well under low-light illumination. As the large-scale adaptation of solar energy is usually constrained by economic viability, we believe that offering a low-cost alternative is the key point for a success.
Ink-jet printing
The inkjet printing technique allows the design of free-form perovskite solar modules. The shapes and areas covered by each layer can be customized according to the requirements.
HOW DOES IT WORK?
Ink-jet printing enables the creation of custom patterns and processing in ambient conditions with a negligible waste of materials. This is facilitated by the drop on demand approach, which is accomplished by driving the nozzles with a piezoelectric material. When the ink-jet head reaches the targeted location, a voltage signal is used to alter the shape of the transducer forcing the drops out of the nozzles. It results in a high-resolution printing that only deposits the materials where it is needed. Lower costs associated with capital and operational expenditures when compared with other techniques such as slot-die coating bring opportunity for significant reductions in the price of the product.
