Photovoltaic Technologies
Photovoltaic (PV) technologies have been in place for decades beginning with the use of treated crystalline silicon, operating as a semiconductor, to generate a flow of direct current electricity when exposed to light. Although crystalline silicon is still the majority of the industry, newer thin film, polymer and semi-conducting molecule PV technologies are evolving and allowing PV use in products such as flexible roofing applications.
