A universal optical approach to enhancing efficiency of organic-based photovoltaic devices

We report a new optical approach that can be used to enhance light harvesting in many different organic-based photovoltaic cells. A transparent polymer microlens array moulded on the light incident surface increases the light path in the active layer and reduces surface reflection, resulting in a 15...

Zusammenfassung:We report a new optical approach that can be used to enhance light harvesting in many different organic-based photovoltaic cells. A transparent polymer microlens array moulded on the light incident surface increases the light path in the active layer and reduces surface reflection, resulting in a 15-60% relative increase in overall cell efficiency.
