Organic photovoltaic (OPV) materials convert light into electrical power. In contrast to typical inorganic silicon cells, OPV materials have a flexible structure and are robust against ambient conditions. Thanks to the freedom of design of OPV, it can be adapted to almost any surface. OPV uses sustainable, carbon-based “organic” materials. The main difference to inorganic photovoltaics is the operating principle: OPV absorbs light in a bulk, not at a discrete interface.
Organic Photovoltaics refers to the semi-conductor materials used being a product of the so-called ‘organic chemistry’ domain. The materials consist of carbon as base material. The working principle of OPV differs significantly from standard PV. Light rays are absorbed in the bulk of the organic layers, not at an interface, leading to strongly different key performance indicators: a good low and diffuse light performance, angular independence and an efficiency that rises with higher temperatures.
The laminates do not need direct light irradiation to operate and can be adapted in shape and colour to almost any surface.
