Opportunities and Challenges for Development of a Mature Concentrating Photovoltaic Power Industry (Revised July 2010)

摘要

This report assesses the current status of the rapidly growing concentrating photovoltaic (CPV) industry, with an eye toward identifying key roadblocks to establishing a mature CPV industry. The original report published in July 2008 focused on the value of using multijunction solar cells and high-concentration approaches. A September 2008 revision added low-concentration approaches using silicon or other inexpensive solar cells. A February 2009 revision updated the report with CPV industry statistics from 2008. The November 2009 revision described industry progress in 2009 and expanded the discussion of Si-based CPV. This July 2010 version of the CPV report updates the status of the industry, including names of new companies, and new developments in the companies' capabilities. It also adds a graph describing the acceptance angle as a function of concentration.
