Impact of Active Layer Thickness and Incident Beam Intensity on Organic Solar Cell Efficiency

Suboori Najam, Brijesh Kumar

Abstract


Organic solar cell is becoming an emerging and popular field in research because of its various economic and environmental merits. This paper presents the impact of thickness of active layer and incident beam intensity on power conversion efficiency (PCE) of organic solar cell. Bulk heterojunction (BHJ) solar cell is considered with organic active layer of MEH-PPV: PCBM material and Indium-Tin-Oxide (ITO) material as transparent anode onto which beam is incident. Subsequently, effect on power conversion efficiency is analysed by varying the active layer thickness from 40nm to 80nm in the 10nm step size. Besides this, impact of incident beam intensity variation also discussed in-depth. The impact on efficiency is implemented using Silvaco Atlas TCAD tool and observed that selecting the optimal value of active layer thickness of 60nm gives highest efficiency. Whereas, on increasing the incident beam intensity, short circuit current density is increased but the power conversion efficiency is decreased. Hence, above analysis is helpful in making organic solar cell of higher efficiency.
