The patents on photovoltaic cells are concentrated in the area of semiconductors for the conversion of solar radiation into electric energy, in the area of generators for the direct conversion of light energy into electric energy and in the area of solar panels adapted for roof structures.
The evolution of the total number of patent documents on photovoltaic cells per country in the period from 2004 to 2013 is shown in Fig. 7. It can be seen that the first two positions are occupied by the United States and China respectively, followed by Japan, Germany and South Korea. Fig. 7.
In 1954, Bell Labs’ Daryl Chapin, Calvin Fuller, and Gerald Pearson created a silicon single-crystal photovoltaic (PV) cell capable of about 6% conversion efficiency with direct sunlight, enough to power an electric device for several hours of a day. 15 Their patent, US patent no 2,780,765, issued in 1957.
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.
In 1941, Russell S Ohl at Bell Labs invented the first silicon solar cell, securing US patent no 2,402,662 on his invention. In the ’662 patent, Ohl described a process of forming a silicon ingot using silicon of a high degree of purity, ideally around 99.85%.
Photovoltaic cell patent registrations are a valuable data set in the analysis and diffusion of PV technology and R&D activities. The dynamics of PV R&D activity is considered high, documented in a large increase in PV patent documents .
