Carbon Fiber from Biomass
September 2016
This study provides a comprehensive overview of carbon fiber (CF) precursors from biomass and their market potential, examining the potential CF production from these precursors, the state of technology and applications, and the production cost where data are available. The main contribution of this study is that it provides technical and market information about each bio-based CF precursor in one document, while other studies have focused on one precursor at a time. The approach allows for a comprehensive view of the CF potential from all biomass sources and offers a detailed reference for both novice and experienced professionals interested in CF production from alternative sources.

Automotive Lithium-ion Cell Manufacturing: Regional Cost Structures and Supply Chain Considerations
April 2016
Manufacturing capacity for lithium-ion batteries (LIBs)—which power many consumer electronics and are increasingly used to power electric vehicles—is heavily concentrated in East Asia. To illuminate the factors that drive regional competitiveness in automotive LIB cell production, this study models cell manufacturing cost and minimum sustainable price, and examines development of LIB supply chains and current LIB market conditions. The study shows that factors driving the cost competitiveness of LIB manufacturing locations are mostly built—supply chain developments and competition, access to materials, and production expertise. Some regional costs—including cost of capital, labor, and materials—are significant and should be considered.

Automotive Lithium-ion Battery Supply Chain and U.S. Competitiveness Considerations
June 2015

This study highlights the U.S. foothold in automotive lithium-ion battery (LIB) production, globally. U.S.-based manufacturers comprise 17% of global production capacity. With increasing demand for electric and hybrid electric vehicles and U.S. vehicle manufacturers' proximity to customers, there is a growing opportunity for the United States to compete globally in the automotive LIB market.

"The Present and Future Silver Cost Component in Crystalline Silicon PV Module Manufacturing"
PV Tech
March 2016
This paper seeks to determine how increased c-Si PV module production might affect future silver demand and prices, as well as the impacts on total c-Si module manufacturing costs. To evaluate how PV's changing demand for silver might affect future silver prices, and the impact in terms of manufacturing costs, some scenarios of silver's contribution to c-Si PV cell manufacturing costs are compiled on the basis of projected changes in demand and price as a result of changes in material intensity. The analysis indicates that an expansion of c-Si production from 55GW/year to 250GW/year results in a 0.05-0.7¢/W increase in manufacturing costs because of higher silver prices.

"Economic Measurements of Polysilicon for the Photovoltaic Industry: Market Competition and Manufacturing Competitiveness"
IEEE Journal of Photovoltaics
March 2015

Illustration of the manufacturing supply chain of wafer-based monocrystalline silicon photovoltaics, which starts with polysilicon, then moves to Czochralski ingot and wafering, then cells, and finally, modules.

Wafer-based monocrystalline silicon photovoltaic manufacturing supply chain

Using the calculations of several economic indicators, this study quantitatively measures the market competition, manufacturing costs, and prices for different technologies in different facility locations, and capital cost requirements to enter today's polysilicon market. The study finds:

  • Improved gross margins and net incomes for major polysilicon manufacturers in 2014, the market has gradually shifted from aggressive pricing strategies for winning market share into a more consolidated market with improved profitability.
  • High capital cost requirements in the polysilicon industry present a significant entry barrier, which could deter new entrants and could also catalyze further consolidation in the polysilicon industry.

"Perspectives on the pathways for cadmium telluride photovoltaic module manufacturers to address expected increases in the price for tellurium"
Solar Energy Materials and Solar Cells
August 2013

This study investigates the impacts of potential tellurium (Te) supply constraints on future cadmium telluride (CdTe) photovoltaic (PV) module deployment and finds:

  • CdTe PV modules can remain cost competitive with future projections for crystalline silicon PV modules—even with a 10-times increase in Te prices—if technology and manufacturing improvement efficiency and thickness targets are realized.
  • If copper mining is relied upon as the sole source of Te, CdTe PV technology may be constrained to around 10 gigawatts (GW) of annual production by 2020 and 40–70 GW of annual CdTe production by 2030.

"Assessing the drivers of regional trends in solar photovoltaic manufacturing"
Energy & Environmental Science
October 2013

In this study, researchers conclude that production scale, not lower labor costs, drives China's current advantage in manufacturing solar photovoltaic energy systems. The study shows:

  • China's historical advantage in low-cost manufacturing is mainly due to advantages of production scale and offset by other country-specific factors, such as investment risk and inflation.
  • Technology innovation and global supply chain development could enable increased manufacturing scale around the world, resulting in broader, subsidy-free PV deployment and the potential for manufacturing price parity in most regions.

A Manufacturing Cost and Supply Chain Analysis of SiC Power Electronics Applicable to Medium-Voltage Motor Drives
March 2017
Wide bandgap semiconductor devices, especially silicon carbide (SiC) devices, are increasingly being considered for use in power electronics applications, where they can improve efficiency, performance, footprint, and—potentially—total system cost compared to traditional silicon devices. This study analyzes the manufacturing costs and supply chains of SiC-based power electronics, in particular, those used in medium-voltage motor drives. By modeling regional cost drivers under different scenarios, this study illustrates regional cost drivers and provides an overview of global supply chain issues to help elucidate key factors that may influence manufacturing location investment decisions.
