Core patents for solar photovoltaic power generation

What are the patents on photovoltaic cells?

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.

What are the technological developments of PV cells?

Sampaio et al. [ 38] described the technological development of PV cells using patents analysis. The results show that the PV patents are concentrated in three areas: PV semiconductor materials, direct conversion of light energy into electric energy, and solar panels adapted for roof structures.

What are the patents for solar cells?

The patents that stand out in this TR are: US20040200520A1 (Metal contact structure for solar cell and method of manufacture), US20050016585A1 (Manufacturing a solar cell with backside contacts), US20060130891A1 (Back-contact photovoltaic cells) and US20070186970A1 (Solar cell and method of fabricating the same).

Are there common patterns of knowledge between solar photovoltaic and earlier industries?

Commonalities in patterns of knowledge between solar photovoltaic and earlier industries are demonstrated. This study first identifies a comprehensive patent dataset for solar PV technologies then differentiates three generations using a three-stage patent extracting methodology.

How has photovoltaic technology developed over the last 30 years?

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 , , , .

What is the technological knowledge basis of photovoltaic-thermal system?

The technological knowledge basis of this route is constituted by patents on solar cells with an integrated diode and bypass method, passing through photovoltaic panels with individually articulated concentrating elements and patents on receivers for concentration of photovoltaic-thermal systems. 5.2.4.
