“…The use of biopolymers and electronic polymers for electrical storage [264][265][266] promises a scalable and very cheap system that could complement organic photovoltaics. Whether organic photovoltaics can contribute to this supplyand I believe that will be the case-the main problem these days is to make all this solar current available also at night.…”

Organic Photovoltaics over Three Decades

The development of organic semiconductors for photovoltaic devices, over the last three decades, has led to unexpected performance for an alternative choice of materials to convert sunlight to electricity. New materials and developed concepts have improved the photovoltage in organic photovoltaic devices, where records are now found above 13% power conversion efficiency in sunlight. The author has stayed with the topic of organic materials for energy conversion and energy storage during these three decades, and makes use of the Hall of Fame now built by Advanced Materials, to present his view of the path travelled over this time, including motivations, personalities, and ambitions.

“…[7,9,10] Alizarin, or 1,2-dihydroxyanthraquinone, is an organic molecule that contains two quinone groups. This redox reaction has inspired researchers to use naturally occurring molecules and polymers containing such functional groups to improve energy density performance in supercapacitors and batteries.…”

“…[7,10,32] PEDOT:PSS is one of the most widely used and studied conductive polymers due to its high electrical conductivity, and chemical and mechanical stability. Conductive polymers have shown great promise for such applications due to their ability to form highly conductive networks and good interface and hosting characteristics for other organic materials.…”

“…These molecules have typically high specific charge but are electrical insulators. [7] There have been reports of impressive capacitance values exceeding 400 F g −1 in supercapacitors using graphene hydrogels functionalized with hydroquinones. This new class of energy storage devices can be thought of as hybrid supercapacitor-batteries, sometimes called redoxenhanced supercapacitors or supercapatteries.…”

availability of renewable energy. While batteries can store large amount of energy per unit mass/volume (energy density), supercapacitors can typically be charged and discharged at relatively higher rates and possess generally a longer lifetime. Lithium-ion batteries (LIB) have one of the highest energy densities among commercial batteries and are already used in grid-scale electrical energy storage systems. However, LIB systems are typically expensive to manufacture, and the restrictions and precautions that apply to largescale LIBs with respect to transportation and operation are rigorous, due to that battery failure may cause fires and explosions. Besides cost, safety, and lifetime, another important aspect, which is less frequently discussed, is the environmental impact of different energy storage technologies; recycling is particularly challenging for LIB technology. Battery technologies rely on a vast array of metals that are extracted through rare earth mining and bottlenecks in the supply of these materials is a challenge. This (surface) mining industry consumes large amounts of energy in itself, leaves our planet with scars and produces great amounts of waste that is utterly difficult and costly to clean. Many of these metals are also toxic and may cause many problems if leakage of the battery components occurs due to improper disposal. Finally, there are no efficient large-scale recycling procedures for many battery technologies (e.g., LIB) as of today. [1] In the search for green energy storage solutions, more and more attention has been focused on organic materials such as using conductive polymers and redox-active molecules. [2] Organic materials can be manufactured and processed at high volumes, at low temperatures, thus enabling a cost-effective production process of energy storage technologies. Many organic materials are flexible and can be dissolved in aqueous or organic solvents, which allows for high-throughput manufacturing techniques, such as using printing, coating, and lamination. Several conductive polymers, such as polythiophene, polypyrrole, polyaniline, and poly(3,4-ethylenedioxythiophene) (PEDOT), have been widely studied and explored as the electrode materials in batteries and supercapacitors. [3] PEDOT is considered to be one of the most chemically, electrochemically, and mechanically stable conductive polymers, especially when combined with the polymeric counter-ion poly(styrene sulfonate) (PSS). Also, PEDOT:PSS has a high mixed ionic and electronic conductivity, but exhibits a relatively low specific capacitance of about 30-40 F g −1 . [4] A supercapacitor made from organic and nature-based materials, such as conductive polymers (PEDOT:PSS), nanocellulose, and an the organic dye molecule (alizarin), is demonstrated. The dye molecule, which historically was extracted from the roots of the plant rubia tinctorum, is here responsible for the improvement in energy storage capacity, while the conductive polymer provides bulk charge transport within the composite electrode.
