Organic Solar Cell Substrates

Researchers at the indian institute of technology kanpur iit kanpur have developed 12x12 cm2 active area 108 cm2 sub modules from organic solar pv cells on a paper substrate that could be used to power flexible electronic devices under an indoor lighting environment.

Organic solar cell substrates.

Lightweight biodegradable and inexpensive materials are desirable to enable low cost photovoltaics. The understanding and manipulation of bhj morphology have been the focus of research in optoelectronic devices. In the flexible organic solar cells flexible substrates polymers are used in most cases having thickness of 10 100 µm are used. The electrical characterization during flight demonstrated in situ their functionality and power generation under space conditions.

Here we report 4 efficient organic solar cells fabricated on paper substrates with a zinc coating acting as the back contact and evaporated moo3 ag moo3 semitransparent top electrodes. On the other hand polymer or polymer inorganic hybrid films with thicknesses as low as 1 10 µm are used as both the substrate and. The modules are said to deliver a power density of up to 12 µw cm2 under illumination from a 1000 lux cool white light. In this article recent advances in understanding and controlling the bhj mor 2020 materials chemistry frontiers review type articles.

Perovskite and organic solar cells exceeded power densities of 14 and 7 mw cm 2 respectively highlighting their. Paper is an environmentally friendly alternative to plastic and other non biodegradable substrates to fabricate flexible organic solar photovoltaic opv cells and panels. Bulk heterojunction solution processed organic photovoltaics opv. The performance of organic solar cells oscs depends on a fine carefully optimized bulk heterojunction bhj microstructure.

From a life cycle perspective substrate materials that can be synthesized from renewable feedstocks at a low cost are particularly attractive for the realization of a sustainable. Developed and evolved over a number of years these substrates have become the mainstay of our own research on organic photovoltaics and perovskite pv but are also used by customers around the world for a wide for a huge array of device types including. Opv cells and modules. Due to the ease of fabrication organic solar cells have been demonstrated on various kinds of substrates such as glass plastic metal foil and paper substrates.

We report on an experiment with perovskite and organic solar cells on board of a rocket flight reaching satellite altitudes for the first time.
