The devices employ an indium tin oxide-free top contact, consisting of thin metal films and an additional organic capping layer for enhanced light in/outcoupling. The solar cell encorporates a bulk heterojunction with the donor material Ph2-benz-bodipy, an infrared absorber.

Transparent, near-infrared organic photovoltaic solar cells for window and energy-scavenging applications
Richard R. Lunt and Vladimir Bulovic

Near-infrared absorbing organic photovoltaics are fabricated that are highly transparent to visible light. By optimizing near-infrared optical-interference, power efficiencies of 1.3±0.1% are demonstrated with simultaneous average visible transmission of >65%. A series-integrated array of these transparent cells is capable of powering electronic devices under near-ambient lighting. This architecture suggests strategies for high-efficiency power-generating windows and highlights an application uniquely benefiting from excitonic electronics. Featured in the New York Times.
