Outdoor Performance of Organic Photovoltaics: Comparative Analysis

Organic photovoltaic (OPV) solar cells represent an emerging and promising solution for low-cost clean energy production. Being flexible semi-transparent having significant advantages over conventional PV technologies, OPV modules innovative even in applications that cannot be based on traditional systems. However, relatively low efficiencies, poor long-term stability, thermal issues have so far prevented the commercialization of this technology. This paper describes two outdoor experimental campaigns compared operation with modules—in particular crystalline silicon copper–indium–selenium (CIS)—and assessed modules’ power generation potential vertical installation facing towards cardinal directions.
