Is to identified the technological development of photovoltaic cells by the analysis of patents. The main depositor countries are the USA, China, Japan, Germany and South Korea. American and Japanese organizations stand out with the highest number of patent registrations.
The number of scientific publications corroborates with the number of patents in terms of representativeness per country, since, through Fig. 6, it can be observed that of the 17,888 publications, the United States, China, Japan, South Korea and Germany were the main countries that published on photovoltaic cells in the period 2004–2013. Fig. 6.
There is a prominence of deposited patents for polymer-based photovoltaic cell technologies, carbon nanostructures, III-V compounds, CdTe and amorphous silicon cells. The objective of this article is to identify the technological development of photovoltaic cells by the analysis of patents.
Photovoltaic technology has developed rapidly over the last thirty years. The main activities of photovoltaic patents began in the late 1950s and the main photovoltaic patent assignees at that time were involved in the space business , . Patent data has been widely used in technology assessment and forecasting , , , .
In the ninth position, with 151 patents, is First Solar, a US company one of the largest manufacturers of photovoltaic solar modules with production units in the United States, Malaysia, Germany and Pakistan.
