    Abstract

    Silicon quantum dot multilayer (Si-QDML) is a promising material for a light absorber of all silicon tandem solar cells due to tunable bandgap energy in a wide range depending on the silicon quantum dot (Si-QD) size, which is possible to overcome the Shockley–Queisser limit. Since solar cell performance is degenerated by carrier recombination through dangling bonds (DBs) in Si-QDML, hydrogen termination of DBs is crucial. Hydrogen plasma treatment (HPT) is one of the methods to introduce hydrogen into Si-QDML. However, HPT has a large number of process parameters. In this study, we employed Bayesian optimization (BO) for the efficient survey of HPT process parameters. Photosensitivity (PS) was adopted as the indicator to be maximized in BO. PS (σ<sub>p</sub>/σ<sub>d</sub>) was calculated as the ratio of photoconductivity (σ<sub>p</sub>) and dark conductivity (σ<sub>d</sub>) of Si-QDML, which allowed the evaluation of important electrical characteristics in solar cells easily without fabricating process-intensive devices. 40-period layers for Si-QDML were prepared by plasma-enhanced chemical vapor deposition method and post-annealing onto quartz substrates. Ten samples were prepared by HPT under random conditions as initial data for BO. By repeating calculations and experiments, the PS was successfully improved from 22.7 to 347.2 with a small number of experiments. In addition, Si-QD solar cells were fabricated with optimized HPT process parameters; open-circuit voltage (V<sub>OC</sub>) and fill factor (FF) values of 689 mV and 0.67, respectively, were achieved. These values are the highest for this type of device, which were achieved through an unprecedented attempt to combine HPT and BO. These results prove that BO is effective in accelerating the optimization of practical process parameters in a multidimensional parameter space, even for novel indicators such as PS.

    Abstract

    Effective strategies for improving the performance of a droplet-based electricity generator (DEG) remain a challenge. Herein, we propose to introduce an intermediate layer of cyclic transparent optical polymer (CYTOP) by adjusting the thickness, injecting ionized ions into the surface, and increasing the surface area. We observed the positive effects of the introduction of a CYTOP layer on outputs, especially with a greater thickness, surface ionized-air modification and larger surface area, which could promote the practical application of DEG in energy harvesting.

    A previous study has shown that large crystal enantiomeric excess can be obtained by inducing sodium chlorate(NaClO3) chiral crystallization from a triangle trimer nanostructure of triangle Au nanoparticles excited by near-infrared circularly polarized laser. This study showed that the magnitude of enantioselective optical force exerted on chiral crystalline clusters, which originates from spatial gradient of optical chirality of near-field of locarized surface plasmon resonance of the nanostrucrure, is possibly sufficient to influence on kinetics of the chiral nucleation process. In addition, fabrication processes of silicon nanostructure for chiral crystallization experiments under near-field of Mie resonance.

    In this study, silicon nanocrystal/silicon oxide composite films were investigated as conductive passivatinon films that provide both passivation to the silicon surface and transport of carriers such as electrons in the out-of-plane direction. Hydrogen plasma treatment (HPT) was performed to improve the surface protection performance of the composite film on the silicon surface. By optimizing the hydrogen plasma treatment process and proposing a two-step HPT method, the passivation performance against silicon surfaces was comparable to that of conventional passivation films. Furthermore, the conductive performance evaluated in terms of contact resistance was also sufficiently low. Therefore, this is an important result that contributes to the realization of conductive passivation films that function universally on various materials.

    In this study, we aim to develop silicon-nanocrystals-embedded silicon oxide passivating layers. The silicon oxide passivating layers including silicon nanocrystals are prepared on crystalline silicon (c-Si) substrates by sandwitching silicon-rich amorphous silicon oxide (a-SiOx) in between oxygen-rich silicon oxide (a-SiOy) and subsequent annealing. The a-SiOy layer can suppress epitaxial growth of the a-SiOx layers and thus higher passivation performance is obtained in comparison with the passivating layers without the a-SiOy. Furthermore, the electrical conductivity increases with annealing temperature. The Si nanocrystals in the silicon oxide passivating layer increase with annealing temperature. These results suggest that the silicon nanocrystals work as a carrier path, indicating the silicon oxide exhibiting good passivation performance and conductivity is successfully fabricated.

    量子ドットを用いた太陽電池は,太陽電池の変換効率が向上するとして非常に魅力的である.本研究では,太陽電池応用のための希釈炭化ケイ素(Si1-xCx)層を中間層に用いた歪み補償系積層ゲルマニウム(Ge)量子ドットの開発を目的とした.積層量子ドットを用いた太陽電池は,pn接合方向への量子ドット間隔の近接化,すなわち,膜厚の薄い中間層を用いることによりキャリアの輸送特性の向上が期待できる.しかし,中間層の薄膜化は,量子ドット層で生じる歪みの伝搬・蓄積を増大させ,積層欠陥の発生により結晶品質が悪化することが知られている.Si1-xCx層は歪み補償層として作用し,量子ドットサイズの増大を抑制することが期待できる.昨年度は,Si1-xCx母材を用いた積層Ge量子ドットの開発に取り組み一定の成果を出せた.そこで本年度では,積層Ge/Si1-xCx量子ドット太陽電池の作製,および中間層膜厚の薄膜化が太陽電池に及ぼす影響を調査した.
    50層積層Si1-xCx上ではGe量子ドット太陽電池はGe/Si量子ドット太陽電池と比較して,量子ドット同士が合体した巨大ドットの発生が抑制されたことにより,キャリアの収集が改善していることが分かった.その結果,開放電圧が改善し,変換効率が向上した. また,中間層膜厚が太陽電池特性に及ぼす影響を調べ,印加電圧によって弱められた内蔵電界の際には,中間層薄膜が薄いほうが外部量子効率が改善,すなわち,キャリアの収集が改善されていることが見出され,量子ドット層でのキャリア輸送の向上を示唆する結果を得た.
    本研究で得られた量子ドットサイズの増大,凝集体の発生を抑制するSi系材料での歪み補償の技術は,Siを用いたヘテロ材料系に有意義な知見を与え,電子デバイスなどの応用に資するものと考えられる.今年度の成果は,国際会議として口頭発表を行い,査読論文誌に投稿する予定である.
