Carrier Transport Enhancement Mechanism in Highly Efficient Antimony Selenide Thin-Film Solar Cell

Yandi Luo et al.

Summary: By introducing aluminum (Al3+) cation into the CdS buffer layer, this study improves the heterojunction interface of an Sb2Se3 solar cell. The energy band alignment of the Sb2Se3/CdS:Al heterojunction is modified from a cliff-like structure to a spike-like structure. As a result, the heterojunction interface engineering suppresses recombination losses and strengthens carrier transport, leading to a high efficiency of 8.41% for the substrate-structured Sb2Se3 solar cell. This study proposes a facile strategy for interfacial treatment and elucidates the related carrier transport enhancement mechanism, paving a bright avenue to overcome the efficiency bottleneck of Sb2Se3 thin-film solar cells.

Carrier recombination suppression and transport enhancement enable high-performance self-powered broadband Sb2Se3 photodetectors

Shuo Chen et al.

Summary: This study presents a two-step thermodynamic/kinetic deposition technique to synthesize Sb2Se3 light absorbing thin film with large crystal grains and desirable orientation, and introduces aluminum cation dopant to modify the optoelectronic properties of CdS buffer layer. The resulting Mo/Sb2Se3/CdS (Al)/ITO/Ag photodetector exhibits self-powered and broadband characteristics with high responsivity, linear dynamic range, ON/OFF switching ratio, signal-to-noise ratio, realistic detectivity, and fast response speed, representing the top level for Sb2Se3-based photodetectors. This work opens up possibilities for self-powered broadband photodetector applications.

All-perovskite tandem solar cells with improved grain surface passivation

Renxing Lin et al.

Summary: Researchers have developed ammonium-cation-passivated Pb-Sn perovskites with long diffusion lengths, enabling high-efficiency all-perovskite tandem solar cells. By enhancing the adsorption of the passivator using a stronger surface-passivator interaction, the carrier diffusion length within Pb-Sn perovskites is doubled, resulting in an efficiency of over 22%. The certified efficiency of 26.4% achieved in the all-perovskite tandem solar cells exceeds that of the best-performing single-junction perovskite solar cells.

Fabrication and Optimization of CdSe Solar Cells for Possible Top Cell of Silicon-Based Tandem Devices

Kanghua Li et al.

Summary: Silicon-based tandem solar cells are considered as an effective method to improve the efficiency and reduce the cost of solar electricity. Recent research has focused on using wide-bandgap perovskite solar cells as the top cell for Si-based tandem devices. However, the instability of perovskite materials has been a major concern. In this study, the neglected CdSe thin-film solar cells were revisited and achieved a champion efficiency of 6.00%. Defects in bulk and interface were identified as the limiting factors for the performance of these cells. This work highlights the great potential of CdSe solar cells as top cells for Si-based tandem devices.

Understanding what limits the voltage of polycrystalline CdSeTe solar cells

Arthur Onno et al.

Summary: In this study, the authors conducted a comprehensive analysis of voltage losses in polycrystalline cadmium selenide telluride solar cells using photoluminescence techniques. They found that the dopant species and concentration, as well as the back contact, play a significant role in voltage losses. They also highlighted the importance of developing contact structures that are both passivating and selective, along with highly luminescent absorbers, to reduce voltage losses.
