研究実績の概要

In my proposed research plan, strategies for building high efficiency metal halide perovskite-based solar cells with up-scaling capabilities and long lifetimes were described. In FY2018, we have made important progress. For example, more than 10 papers have been published, in which we acknowledged the funding support from Kakenhi Grant Number JP18K05266 (see Journal Articles section). I was invited to write a perspective article [2], a review article [4], and a research highlight article [13]. The main findings from our original research are summarized below:(1) We have achieved the main task of up-scaling processes based on our chemical vapor deposition (CVD) technique [10,11]. Interface engineering [7] and thermally stable Cs-based perovskite allowed CVD fabrication of large area solar modules with efficiencies of 9.3% fabricated on 10 cm x 10 cm substrates with enhanced stability [11].
(2) We have achieved important fundamental understanding on the degradation mechanisms in CH3NH3PbI3 [1,5,12]. Our work revealed the existence of reversible (CH3NH2 + HI) and an irreversible (CH3I + NH3) decomposition reactions in CH3NH3PbI3 perovskite. Subsequent strategies for improving stability are currently being studied in my group [4].
(3) We have further progressed to improve our CH3NH2-treatment method leading to monolithic-type grains [6]. Our proposed method is shown to significantly improve the grain boundary-related issues.

1: 当初の計画以上に進展している

理由

In addition to the descriptions provided in the “Summary of Research Achievements” section, below are further other outcomes from the present research:
(1) We obtained further fundamental knowledge on the spiro-MeOTAD layer. Its optimization is essential for the efficient charge (hole) extraction and transport [3].
(2) Two publications that report up-scalability of perovskite solar modules from my group [6,7] have received wide attention and were featured in several local and overseas media. Please see Remarks/Webpage section.

今後の研究の推進方策

As proposed in my original research plan, we have achieved the main tasks of module design optimization and successful large-area solar module fabrication by the CVD method [7,10,11]. Our next goal is to further optimize the CVD protocols aiming at higher efficiencies. In addition, substantial knowledge on the degradation processes in perovskite materials were obtained [1,5,12]. The short lifetime of perovskite solar cells is currently a major issue impeding further commercialization [4]. Therefore, we plan to study systematically the possible new chemical compound candidates by employing the chemical composition engineering or alloying.
In addition to the optimization of solar module devices, guidance and feedback/verification from surface science analytical tools are also essential for efficiently achieving our goals. Particular efforts will be given to the scanning tunneling microscopy technique on new perovskite materials as described in reference [8]. Atomic-level understanding of perovskite structure is crucial for rational design approach of new photovoltaic materials.
