6 FAQs about [Photovoltaic losses in organic solar cells]
Do organic solar cells suffer more energy loss than inorganic halide perovskite?
Organic solar cells (OSCs) currently suffer larger energy losses than their inorganic and metal halide perovskite counterparts. In this perspective, we lay out the case for why this is not necessarily an intrinsic limitation in OSCs and provide paths forward for reducing energy loss to below 0.5 eV.
What causes a low voltage in organic solar cells?
The open-circuit voltage of organic solar cells is usually lower than the values achieved in inorganic or perovskite photovoltaic devices with comparable bandgaps. Energy losses during charge separation at the donor–acceptor interface and non-radiative recombination are among the main causes of such voltage losses.
How do organic solar cells affect energy conversion efficiencies?
For state-of-the-art organic solar cells (OSCs), there are additional pathways that further increase energy loss and, presently, limit power conversion efficiencies to less than 15%. 4 Primarily, the excitonic nature of photogenerated electron-hole pairs in an organic semiconductor fundamentally alters the nature of carrier generation.
What are solar cell losses?
These losses may happen during the solar cell's light absorption, charge creation, charge collecting, and electrical output processes, among others. Two types of solar cell losses can be distinguished: intrinsic and extrinsic losses (Hirst and Ekins-Daukes, 2011).
Why do solar cells lose power?
Losses in solar cells can result from a variety of physical and electrical processes, which have an impact on the system's overall functionality and power conversion efficiency. These losses may happen during the solar cell's light absorption, charge creation, charge collecting, and electrical output processes, among others.
Does acceptor fluorination increase voltage loss in organic solar cells?
Acceptor fluorination leads to increased voltage losses in organic solar cells. The increased voltage loss is associated with increased reorganization energy. A side chain modification strategy is proposed to address the voltage loss issue.
