Special Issue Information

Dear Colleagues,

Solar cell is a technique to convert solar energy to electricity and promote the development of a carbon-free society. In the past decade, many emerging photovoltaic techniques such as perovskite solar cells (PSCs), organic photovoltaics (OPV), quantum dot solar cells (QDSCs) and inorganic thin film solar cells have been comprehensively studied beside the mature crystal silicon (c-Si) solar cells.

Among them, the power conversion efficiency (PCE) of PSCs is undergoing a rapid increase from 3.8% to 25.7% due to the outstanding optoelectronic properties of the metal halide perovskite materials, such as long carrier diffusion length, low cost, and solution processability. There are many aspects such as the device structure, stability, tandem architecture, scalable production, and multi-functional device of PSCs to be discussed before their industrialization.

Besides the PSCs, recently, the PCE of OPV is approaching 20% benefit from the developing of non-fullerene electron acceptors. Additionally, QDSCs with a facile low-temperature deposition process and strong visible-to-infrared absorption have achieved a PCE over 18%. Inorganic thin film photovoltaics such as Cu2ZnSnS4 (CZTS) and Cu2ZnSnSe4 (CZTSe) solar cells with abundant raw materials and a PCE around 12-13% have also attracted increasing attention. These new types of advanced solar cells will likely further promote the solar energy conversion and decrease the cost of production, and extend the application scenarios to indoor photovoltaics, building-integrated photovoltaics, flexible electronics, and outside space application. In this Special Issue, we aim to collect the research topics of preparation and application of advanced solar cell materials and devices based on, but not limited to, the solar cell types mentioned above. We kindly invite you to submit a manuscript(s) for this Special Issue. Full papers, communications, and reviews are all welcome.

Ternary organic solar cells (OSCs) have attracted intensive studies due to their promising potential for attaining high-performing photovoltaics, whereas there has been an opening challenge in minimizing the open circuit voltage (Voc) loss while retaining the optimal carrier extraction in the multiple mixture absorbers. Here, we systemically investigate a ternary absorber comprised of two acceptors and a donor, in which the resultant Voc and fill factor are varied and determined by the ratios of acceptor components as a result of the unbalance of non-radiative recombination rates and charge transport. The transient absorption spectroscopy and electroluminescence techniques verify two distinguishable charge-transfer (CT) states in the ternary absorber, and the mismatch of non-radiative recombination rates of those two CT states is demonstrated to be associated with the Voc deficit, whilst the high-emissive acceptor molecule delivers inferior electron mobility, resulting in poor charge transport and a subpar fill factor. These findings enable us to optimize the mixture configuration for attaining the maximal-performing devices. Our results not only provide insight into maximizing the photovoltage of organic solar cells but can also motivate researchers to further unravel the photophysical mechanisms underlying the intermolecular electronic states of organic semiconductors.
