Book Description
NREL scientists have worked with Washington State University and the University of Tennessee to improve the maximum voltage available from CdTe solar cells. Changes in dopants, stoichiometry, interface design, and defect chemistry improved the CdTe conductivity and carrier lifetime by orders of magnitude, thus enabling CdTe solar cells with open-circuit voltages exceeding 1 volt for the first time. Values of current density and fill factor for CdTe solar cells are already at high levels, but sub-par voltages has been a barrier to improved efficiencies. With voltages pushed beyond 1 volt, CdTe cells have a path to produce electricity at costs less than fossil fuels.

Book Description
This book assists in the adoption of the sustainable cross-sectoral nexus approach of agrivoltaics, which can provide a quite significant untapped potential for the sustainable development of humanity. Increasing demand for water, energy and food, due to population growth and urbanization, is aggravated by unprecedented extreme weather and climatic conditions. This situation is likely to undermine the sustainable and peaceful development of humanity. Today, more than ever, there is an imperative need to support the identification and development of practical solutions, where the use of a nexus approach can lead to improved outcomes in the integrated management of water–energy–food–ecosystem (WEFE) resources. This book disseminates the current knowledge of the modern approach of agrivoltaics, providing a comprehensive state of the art on the field, discussing the current status, the challenges and the future perspectives for their further development. This new currently in-depth unexplored topic will be covered thoroughly by the present book, which will attract the readership of both the scientific and industrial research communities, even of people who are dealing with cultivations, promoting the development in the field, from conceptual designs to practical realizations.

Book Description
This CRADA involves analyses on a variety of CdTe and CdTe-PV related materials, test structures, and solar cells produced at FSLR or NREL. Single-crystal (sx) material will be primarily MBE grown and provided by FSLR. Joint activities are focused on establishing the appropriate quality metrics as a basis for high performing sx devices and to study the dopability of the material. Polycrystalline (px) materials will be provided by NREL, FSLR, or fabricated jointly. Px activities are focused on the characterization of performance limiting mechanisms including bulk defects, grain boundaries, and the hetero-interface. A combination of growth, characterization, and theory will be applied. Analysis will include techniques that are well established in CdTe research at NREL (e.g., LIV/DIV/CV, AS/DLTS, LTPL, TRPL) as well as techniques that have not been widely applied to the PV part of CdTe technology (e.g., PCD, CL, uPL, SE).

Book Description
Lucintech and NREL will collaborate to develop flexible CdTe solar cells on flexible glass using sputtering and other deposition technologies. This initial work will be conducted under the DOE funded Foundational Program to Advance Cell Efficiency (FPACE) 1 project, and the interaction with Lucintech will focus on scaling up and transferring the high efficiency cell processes to module production on a pilot line.

Book Description
Thanks in part to years of collaboration with the National Renewable Energy Laboratory (NREL), a manufacturer of thin-film solar modules has grown from a small garage-type operation to become the world's largest manufacturer of solar modules. First Solar, Inc. now manufactures cadmium telluride (CdTe) solar modules throughout the world, but it began in Ohio as a small company called Solar Cells,Inc.

Book Description
This book gives a comprehensive introduction to the field of photovoltaic (PV) solar cells and modules. In thirteen chapters, it addresses a wide range of topics including the spectrum of light received by PV devices, the basic functioning of a solar cell, and the physical factors limiting the efficiency of solar cells. It places particular emphasis on crystalline silicon solar cells and modules, which constitute today more than 90 % of all modules sold worldwide. Describing in great detail both the manufacturing process and resulting module performance, the book also touches on the newest developments in this sector, such as Tunnel Oxide Passivated Contact (TOPCON) and heterojunction modules, while dedicating a major chapter to general questions of module design and fabrication. Overall, it presents the essential theoretical and practical concepts of PV solar cells and modules in an easy-to-understand manner and discusses current challenges facing the global research and development community.
