Special Issue Information

Dear Colleagues,

Recently, there has been a strong demand for photovoltaic technology to resolve the current issues regarding carbon neutrality. Conventional silicon (Si) solar cells provide high conversion efficiency and preferred long lifetimes. To deliver more efficient and low-cost electric power generation, emerging photovoltaic technologies such as quantum dot, organic and perovskite-based nanomaterials have revealed remarkable advances in their power conversion efficiencies. We are pleased to invite you to submit related review or research articles regarding these issues.

This Special Issue aims to publish original work on advanced nanomaterial synthesis and fabrication processes used in any type of emerging photovoltaic cells (quantum dot, organic and perovskite-based photovoltaic cells). Submissions on nanomaterials regarding charge transport layers as well as photo-absorber layers that have unique properties for highly efficient and stable solar cells are highly welcome. Transparent conducting nanomaterials are also very important in creating efficient conversion devices.

In this Special Issue, original research articles and reviews are welcome. Research areas may include (but not limited to) the following:

  • Nanomaterial synthesis/fabrication for charge transport layers or photo-absorbing layers
  • Nanomaterial processing for solar cells

The bulk-heterojunction (BHJ) system that uses a π-conjugated polymer as an electron donor, and a fullerene derivative as an electron acceptor, is widely used in organic solar cells (OSCs) to facilitate efficient charge separation and extraction. However, the conventional BHJ system still suffers from unwanted phase segregation caused by the existence of significant differences in surface energy between the two BHJ components and the charge extraction layer during film formation. In the present work, we demonstrate a sophisticated control of fast film-growth kinetics that can be used to achieve a uniform distribution of donor and acceptor materials in the BHJ layer of OSCs without undesirable phase separation. Our approach involves depositing the BHJ solution onto a spinning substrate, thus inducing rapid evaporation of the solvent during BHJ film formation. The fast-growth process prevents the fullerene derivative from migrating toward the charge extraction layer, thereby enabling a homogeneous distribution of the fullerene derivative within the BHJ film. The OSCs based on the fast-growth BHJ thin film are found to exhibit substantial increases in JSC, fill factor, and a PCE up to 11.27 mA/cm2, 66%, and 4.68%, respectively; this last value represents a remarkable 17% increase in PCE compared to that of conventional OSCs.
