Enhancing Power Conversion Efficiency of Bulk Hetero Junction (BHJ) Organic Solar Cells (OSCS) by Stimulation

Research output: Chapter in Book/Report/Conference proceedingChapterpeer-review

Abstract

Organic solar cells (OSCs) are emerging as promising cadidates for low-cost, highefficiency solar cells but there is the need for further improvement in their performances. Simulation techniques play a crucial role in studying, characterising and enhancing the  power conversion efficiency (PCE) of these devices. In this chapter, we present: 1) simulation of the PCE of a ternary organic solar cell (TOSC) with an active layer consisting of PBDB-T-2F and two non-fullerene (NF) acceptor materials, Y6 and SF(BR)4, resulting in a PCE of 20.87%, 2) an alternative approach to simulate the PCE of bulk heterojunction (BHJ) OSCs, as a product of efficiencies of absorption (????????), dissociation and extraction, and 3) characterisation of exciton generation carried out in three BHJ OSCs, OSC2: An inverted NF BHJ OSC, OSC4: A conventional NF BHJ OSC and OSC5: A conventional fullerene BHJ-OSC. It is expected that the contents of this chapter may help readers getting a clear understanding of the conventional and alternative device simulation techniques as well as an insight into the characterisation of exciton generation in the active layer of these devices.
