High open‐circuit voltage CuSbS₂ solar cells achieved through the formation of epitaxial growth of CdS/CuSbS₂ hetero‐interface by post‐annealing treatment

Progress in Photovoltaics Research and Applications (2018)

Yuanfang Zhang Jialiang Huang Chang Yan Kaiwen Sun Xin Cui

Abstract The earth‐abundant and environmentally‐friendly CuSbS 2 solar cells have been struggling with low device performance, especially poor open circuit voltage (V oc ). In this work, post‐annealing treatment of the CuSbS 2 /CdS heterojunction performed on CuSbS 2 ‐based solar cells was firstly reported. With this treatment, we demonstrated CuSbS 2 solar cells with a record V oc of 622 mV. The improvement of device performance was found peaked at 250°C post‐annealing which mainly benefits from the significantly boosted open‐circuit voltage and short‐circuit current. The study of microstructure by high‐resolution transmission electron microscopy revealed that such improvement could be attributed to the formation of epitaxial CuSbS 2 /CdS hetero‐interface upon heat treatment, which reduces the interface defect density that may lead to reduced V oc deficit. Besides, results of photoluminescence and time‐resolved photoluminescence measurements also indicated improved electrical properties of completed devices with higher photoluminescence intensity and longer minority carrier lifetime.

Enhancing PbS Colloidal Quantum Dot Tandem Solar Cell Performance by Graded Band Alignment

The Journal of Physical Chemistry Letters (2019)

Yijun Gao Jianghui Zheng Weijian Chen Lin Yuan Zhi Li Teh

Colloidal quantum dot solids are attractive candidates for tandem solar cells because of their widely tunable bandgaps. However, the development of the quantum dot tandem solar cell has lagged far behind that of its single-junction counterpart. One of the fundamental problems with colloidal quantum dot solar cells is the relatively small diffusion length, which limits the quantum dot absorbing layer thickness and hence the power conversion efficiency. In this research, guided by optical modeling and utilizing a graded band alignment strategy, a two-terminal monolithic solution-processed quantum dot tandem solar cell has been successfully fabricated and a power conversion efficiency of 6.8% has been achieved. The band grading approach utilized the complementary tuning of work functions and band alignment through judicious choices of the nanoparticle surface chemistry and quantum dot confined size. This work demonstrates a general approach to improving the efficiency for tandem thin-film solar cells.

Decomposing the Bid-Ask Spread in a Segmented Equity Market: Analyzing Chinese A Shares Versus B Shares

Emerging Markets Finance and Trade (2012)

Zhian Chen Xin Cui

Because of a regulatory policy change in February 2001, the segmentation of the Chinese stock market significantly decreased. Using this event, we show that the Chinese A-share market is more informationally efficient than the B-share market, both before and after the opening of the B-share market. Furthermore, after the event, both the adverse selection and the order-processing component of B shares decreased, as a result of a larger investor base and possibly a lower proportion of informed investors. This study thus sheds new light on the market segmentation and its effect on transaction costs.

Interface Recombination of Cu₂ZnSnS₄ Solar Cells Leveraged by High Carrier Density and Interface Defects

Solar RRL (2021)

Jianjun Li Jialiang Huang Yanchan Huang Hitoshi Tampo T. Sakurai

Kesterite Cu 2 ZnSnS 4 (CZTS) solar cell has emerged as one of the most promising thin‐film photovoltaic technologies that allows for cheap, clean, and efficient renewable power in the future. Nevertheless, limited by the large photovoltage deficit caused by severe interface recombination, the potential of CZTS solar cells is far from being fully tapped. Herein, it is demonstrated that the carrier density of the CZTS absorber and the acceptor‐like interface defects are two critical factors governing the interface recombination in addition to the unfavorable conduction band alignment. Results of device simulation suggest that passivating the acceptor‐like interface defects combined with appropriate absorber carrier density is the essential way to promote the photovoltage and efficiency of CZTS solar cells to a more competitive level. It is believed that these results could be generally applicable to the interface recombination of other heterojunction solar cells.
