Zusammenfassung, Abstract
The organic bulk hetero-junction solar cell has remarkable advantages such as low cost, mechanical flexibility and simple process techniques.Recently, low-band gap photoactive materials have obtained a significant attention due to their potential to absorb a wider range of the solar spectrumto attain higher power conversion efficiencies. Many low-band gap photoactive materials, however, still show a relatively low external quantum efficiency of less than 60% [1]. One possible approach to improve the device performance is to increase the light absorption in the active layer. This may, amongst other approaches, be achieved by using nano- or micro-structures that trap light at specific wavelengths [2], or by using the localized surface plasmon resonance effect of metal nanoparticles in the devices. In this work, we theoretically studied planar polymer solar cell based on finite-difference time-domain approach. Also, we have optimized reference polymer solar cells with PTB7:PC70BM as active layer, using two different electron transport layers. The aim is to integrate Gold nanoparticles in the reference devices, and support the integration theoretically.
