A top-down analysis: Determining photovoltaics RandD investments from patent analysis and RandD headcount

Abstract:: For alternative energy technologies like photovoltaics (PV), the analysis of Research and Development (RandD) expenses is important to observe and understand market dynamics. This is, in turn, essential for policymakers. However, the quantitative evaluation of global corporate RandD investments is a challenging task due to unavailability or high scatter of precise data. Here we present a top-down approach to estimate the current and global historic cumulated PV RandD investments based on international PV patent applications. High growth rates of PV-related patents and RandD headcount accompany growth and development of the PV market and are an excellent indicator to analyze RandD investments. With this approach, current annual corporate PV RandD investments are found to be about 6000. m€ and show a rapidly increasing trend on a global scale. © 2013 Elsevier Ltd.
