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 .
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.
Other groups such as that of Daryl Chapin et al. from the Bell laboratories in 1954, Hoffman Electronics Corporation in 1960, etc. have all contributed to the development of PV solar technology. The increase in research and development in alternative energy generation technology was primarily due to the oil crisis in the 1970s.
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 , , , .
The technical review of these patents has shown the global continuous efforts for improving PV technologies and addressing their technical challenges. Taken together, the results show that the PV technological system has been deeply connected with patenting activities since its emergence in the past century.
Photovoltaic (PV) energy conversion technology is concerned with the direct conversion of solar energy (electromagnetic radiation from the sun) into electricity. The technology entails the generation of electrical power by converting solar radiation into a flow of electrons in the form of direct current (DC).
