6 FAQs about [Solar cell bottleneck problem]

How can organic solar cells improve performance?

A critical bottleneck for improving the performance of organic solar cells (OSC) is minimising non-radiative losses in the interfacial charge-transfer (CT) state via the formation of hybrid energetic states. This requires small energetic offsets often detrimental for high external quantum efficiency (EQE).

Is there a conflict of interest in organic solar cells?

The authors declare no conflict of interest. Abstract Over the last two decades the organic solar cell community has synthesized tens of thousands of novel polymers and small molecules in the search for an optimum light harvesting material. T

Do solar cells have radiative losses?

According to the Shockley and Queisser description, an ideal solar cell exhibits only unavoidable radiative losses 1. Operated as a light-emitting diode, such a device should deliver electroluminescence (EL) external quantum efficiency (EQE EL) of unity 2.

Can organic solar cells reduce non-radiative losses in the interfacial charge-transfer state?

Nature Communications 12, Article number: 1772 (2021) Cite this article A critical bottleneck for improving the performance of organic solar cells (OSC) is minimising non-radiative losses in the interfacial charge-transfer (CT) state via the formation of hybrid energetic states.

What's next for organic solar cells?

The Frontiers and Challenges The power conversion efficiency (PCE) of organic solar cells (OSCs) is improved dramatically in recent years and now approaches >19% for single-junction cells and >20% for tandem cells. Therefore, the practical use of OSCs is becoming a reality.

Why is organic photovoltaics development so slow?

Part of the reason for this slow progress in organic photo-voltaics (OPV) development is a lack of timely and detailed feedback to chemists from device engineers. [ 13, 14] Typically a new material will be synthesized and then used to fabricate a few test devices using a handful of solvents and a few annealing temperatures.
