    Improving the charge separation and collection at the buffer/absorber interface by double-layered Mn-substituted CZTS by Lie, Stener, Sandi, Mario Indra, Tay, Ying Fan, Li, Wenjie, Tan, Joel Ming Rui, Bishop, Douglas M., Gunawan, Oki, Wong, Lydia Helena

    Published 2020
    “…With this structure, we obtained our best performance cell with power conversion efficiency (PCE) of 5.73% and Jsc of 17.86 mA/cm2. The improved Jsc is attributed to increased depletion width and higher activation energy of the limiting recombination mechanism as shown by capacitance-voltage and temperature dependent current-voltage measurements. …”

    Efficiency enhancement and doping type inversion in Cu₂CdSnS₄ solar cells by Ag substitution by Ibrahim, Ahmad, Lie, Stener, Tan, Joel Ming Rui, Swope, Ryan, Medaille, Axel Gon, Hadke, Shreyash, Saucedo, Edgardo, Agrawal, Rakesh, Wong, Lydia Helena

    Published 2024
    “…Further optoelectronic and photovoltaic characterization reveals that adding 5% Ag concentration improves Cu2CdSnS4 device performance to 7.72%, mainly due to superior film quality and improved interface properties. …”

    Robust microhoneycomb-like nanofibrous aerogels derived from cellulose and lignin as highly efficient, low-resistant and anti-clogging air filters by Ma, Daphne Xiu Yun, Zeng, Zhihui, Wang, Zhe, Xu, Lulu, Zhang, Youfang, Ang, Jia Ming, Wan, Man Pun, Ng, Bing Feng, Lu, Xuehong

    Published 2022
    “…In particular, a high filtration efficiency of 99.86% with a fairly low pressure drop (ΔP) of 59.5 Pa could be achieved for 0.1 μm particles at the face velocity of ∼5 cm s−1, for which the corresponding quality factor (QF) is significantly higher than that of reported aerogel air filters fabricated using predominantly natural materials. …”
