Since the demonstration of the first practical solar cell 60 years ago, research on novel materials, improved solar cell design and structure, and innovative manufacturing processes have all contributed to a continuous increase in the efficiency of photovoltaic (PV) devices.
While dye sensitization as the basis for color photography has been accepted for a very long time,1 attempts to use this principle for the conversion of solar light to electricity generally had resulted only in very low photocurrents, below 100
This article reviews the use of block copolymers to coat a surface to make unique nanoscale patterns on a substrate (shown below). Using this method, as opposed to etching with a laser, can improve resolution from the current limit of
Dr. Chan and researchers highlight flexible transistors are the building blocks of next-generation soft electronics. Among all the reported material systems that can be fabricated by researchers, such as circuits, biosensors, stretchable displays, and others,1–5 small molecular weight organic semiconductors
Organic photovoltaics (OPVs) represent a low-cost, lightweight, and scalable alternative to conventional solar cells. While significant progress has been made in the development of conventional bulk heterojunction cells, new approaches are required to achieve the performance and stability necessary to
This article briefly reviews the methods and mechanisms for the formation of molecular monolayers on silicon surfaces, the properties of these monolayers and current perspectives regarding their application in molecular electronic and sensing applications.
Flexible electronic circuits, displays, and sensors based on organic active materials will enable future generations of electronics products that may eventually enter the mainstream electronics market.
In the emerging field of organic printable electronics, such as OLEDs and organic photovoltaics (OPVs), there is a significant need for improved organic conducting and semiconducting materials. This paper reports our recent progress in two fields: 1) the development of
A drawable Carbon Nanotube (CNT) array is a special type of CNT forest, in which individual nanotubes are aligned and grown vertically on a substrate through a chemical vapor deposition (CVD) process. Most strikingly, a macroscopically aligned, pure, and pristine
Solution-processed organic photovoltaic devices (OPVs) have emerged as a promising clean energy generating technology due to their ease of fabrication, potential to enable low-cost manufacturing via printing or coating techniques, and ability to be incorporated onto light weight, flexible substrates.
The field of organic electronics has emerged as the next-generation technology potentially enabling ultra-thin, large-area, and/or flexible devices, consisting of organic field-effect transistors (OFETs), organic light-emitting diodes (OLEDs), and organic photovoltaics (OPVs).
Professor Tokito and Professor Takeda share their new materials, device architecture design principles, and performance optimization protocols for printed and solution-processed, low-cost, highly flexible, organic electronic devices.
