Visibly transparent polymer solar cells produced by solution processing
ACS Nano, 2012Co-Authors: Chun-chao Chen, Steve Hawks, Yue Bing Zheng, Letian Dou, Yu-guang Yang, Tze-bin Song, Choong-heui Chung, Rui Zhu, Paul S Weiss, Gang Li, Yang YangAbstract:Visibly transparent photovoltaic devices can open photovoltaic applications in many areas, such as building-integrated Photovoltaics or integrated photovoltaic chargers for portable electronics. We demonstrate high-performance, visibly transparent polymer solar cells fabricated via solution processing. The photoactive layer of these visibly transparent polymer solar cells harvests solar energy from the near-infrared region while being less sensitive to visible photons. The top transparent electrode employs a highly transparent silver nanowire-metal oxide composite conducting film, which is coated through mild solution processes. With this combination, we have achieved 4% power-conversion efficiency for solution-processed and visibly transparent polymer solar cells. The optimized devices have a maximum transparency of 66% at 550 nm.

Organic semiconductors and their applications in photovoltaic devices
Polymer Reviews, 2012Co-Authors: Jason D. Myers, Jiangeng XueAbstract:In recent years, organic semiconductors have emerged as a promising and, in some situations, viable commercial alternative to traditional inorganic materials such as silicon. Organic-based light emitting diodes, photovoltaic devices, photodetectors, and transistors have attracted intense interest in the scientific community. In this review, we first present a discussion of the fundamental electronic nature of organic semiconductors, processing techniques, and their application to two main classes of optoelectronic devices, light emitting diodes, and Photovoltaics. The second part of the review introduces organic Photovoltaics in depth, including their operation principles, development history, current state of the art, and routes for further improvement. © 2012 Taylor and Francis Group, LLC.

Perspectives on Organic Photovoltaics
Polymer Reviews, 2010Co-Authors: Jiangeng XueAbstract:Organic Photovoltaics have been considered as a future low-cost solar energy conversion solution, and have attracted tremendous academic and industrial interests in recent years due to many technological advantages of organic semiconductors (including both small molecules and conjugated polymers). Here we describe the basic design and operation of organic photovoltaic cells as well as the important metrics for characterizing their performance. An overview of the three review articles included in this special issue on organic Photovoltaics is provided, followed by discussions on the remaining significant challenges for the further development and commercialization of the organic photovoltaic technologies.

Advances in hybrid solar photovoltaic and thermoelectric generators
Renewable and Sustainable Energy Reviews, 2017Co-Authors: Priscilla Huen, Walid A DaoudAbstract:Development of renewable energies, particularly solar energy, is crucial for meeting future energy needs. Solar light and thermal energy can provide sufficient electricity needed in daily life. In this pursuit, Photovoltaics and thermoelectrics have been developing for energy conversion. While Photovoltaics mainly convert the UV and visible regions of the solar spectrum, thermoelectrics utilize the IR region. Combining the photovoltaic and thermoelectric effects can extend the effective spectrum range. In recent years, there have been studies on hybrid photovoltaic/thermoelectric systems toward improved conversion efficiency. This review intends to discuss the underlying concepts of Photovoltaics and thermoelectrics and summarizes the current research accomplishments and the various approaches used to optimize hybrid photovoltaic/thermoelectric systems. As such, this review encourages further research into hybrid generators due to the promising results achieved. Future prospects and suggestions of potential approaches for further development of these generators are also discussed.
