New Organic Polymers for Solar Cells

Abstract

From the moment of conductive polyacetylene discovery, semiconducting polymers and other organic thin films and multilayers are important for a wide range of applications, including electronics, photovoltaics and sensors. The main idea of this chapter is the synthesis of new conjugated donor and acceptor polymers and development of organic solar cells on their basis. As donor polymers were used modified polyanilines (PANIs) and its dopants, as acceptor compounds-the fullerene C 60 derivatives. Experimental prototypes of organic solar cells were obtained on the basis of binary donor-acceptor layers and bulk heterojunctions, consisting of novel polyaniline derivatives and fullerene-contained polymers. The current-voltage characteristics of solar cells were measured and the values of such parameters, such as open-circuit voltage, short-circuit current, fill factor and power conversion efficiency, were calculated. Comparison of parameters of the various types of organic solar cells was held.

Latest Updates of Single-Junction Organic Solar Cells up to 20% Efficiency

“…Organic solar cells (OSCs) have emerged as a sustainable alternative to inorganic solar cell technology for power generation [1][2][3][4][5][6][7]. They can be fabricated using low-temperature solution processing and are widely considered to be an efficient type of solar energy harvesting device due to their low cost, short energy payback time, and mechanical flexibility [8][9][10][11].…”
