Recent developments in conjugated-polymer-based photovoltaic elements are reviewed. The photophysics of such photoactive devices is based on the photo-induced charge transfer from donor-type semiconducting conjugated polymers to acceptor-type conjugated polymers or acceptor molecules such as Buckminsterfullerene, C60. This photo-induced charge transfer is reversible, ultrafast (within 100 fs) with a quantum efficiency approaching unity, and the charge-separated state is metastable (up to milliseconds at 80 K). Being similar to the first steps in natural photosynthesis, this photo-induced electron transfer leads to a number of potentially interesting applications, which include sensitization of the photoconductivity and photovoltaic phenomena. Solar cells use freely available sunlight to make electricity. At the present time, solar electricity does not come cheap, because solar panels are rather expensive. Now imagine that we could reduce costs by printing solar panels like we print newspapers! We can do just that with plastic solar cells. In this book, we explain the basic working principles of these novel plastic solar cells and then show how a stunning threefold increase in solar energy efficiency can be achieved by including a special additive to the printing ink. The function of such a special additive seems almost magical, but as scientists we know that true magic is really rare and we simply had to find out why and how it works.
There is a significant increase in the demand for alternative energy sources is due to growth in industrial sector and rise in population. Solar energy is the most abundant form of renewable energy. Photovoltaic (PV) cell is one of the way to connect solar energy. PV cells convert sunlight directly to electricity and can be influential in meeting the world's energy demand. PV systems are being used in a variety of applications because of its lightweight and flexibility. Plastic solar cells are used for coating on the back of electronics so it can supply power to the portable electronics equipment such as PDAS, laptops, and pocket calculators. The plastic solar cells also open up opportunities for the wearable computing devices.
This book is intended to provide a comprehensive coverage of modern 'plastic' solar cells, a wide-ranging topic that spans materials science, physics, and chemistry. The aim of this book is to provide a primer for non-experts or researchers in related fields who are curious about this rapidly growing field of interdisciplinary research. It introduces the basic concepts of plastic solar cells and design rules for maximizing their efficiency, including modern quantum chemical calculations that can aide in the design of new materials.
