Solution Processed Inorganic Thin-Film Photovoltaic Devices

拉夫堡大学的可再生能源系统技术中心（CREST）获得了EPSRC的资助，开展了一项利用溶液处理技术开发薄膜太阳能电池的研究项目。拉夫堡大学在这个名为“溶液处理无机薄膜光伏器件（SolPV）”的项目中所扮演的角色，旨在开发铜铟镓二硒化（CIGS）薄膜太阳能电池，其功率转换效率高于15%，使用可扩展的制造技术，依赖于胺-硫醇溶液化学。一些关键策略包括：优化吸收体前体形成，以实现基于溶液处理（如喷涂、槽模等）的可扩展制造方法。设计热处理策略，以实现可控的再结晶和吸收塔的成分分级。吸收层/缓冲层界面工程提高太阳能电池性能，包括最终去除含镉化合物。该学生将致力于薄膜CIGS太阳能电池的制造、表征和分析，旨在提高器件性能。利用各种结构、组成和光电表征技术和分析方法，博士生将致力于发展对器件中基本限制过程的理解，最终将功率转换效率提高到15%以上。

The Centre for Renewable Energy Systems Technology (CREST), at Loughborough University have been awarded funding from the EPSRC to undertake a program of research to develop thin film solar cells using solutionprocessing techniques. Loughborough's role in the project, named ""Solution-Processed Inorganic Thin-Film Photovoltaic Devices (SolPV)" aims to develop copper indium gallium diselenide (or CIGS) thin film solar cells with power conversion efficiencies above 15% using scalable manufacturing techniques, reliant on amine-thiol solution chemistry.Some of the key strategies include:Optimisation of the absorber precursor formation to implement scalable manufacturing methods based on solution processing (such as spray coating, slot die, etc).Design thermal processing strategies to achieve controlled recrystallisation and compositional grading of the absorber.Interface engineering of the absorber/buffer interface to improve solar cell performance, including the ultimate removal of cadmium containing compounds.The student will work on the fabrication, characterisation and analysis of thin film CIGS solar cells, with an aim to improve the device performance. Using a variety of structural, composition, and opto-electronic characterisation techniques and analysis methods, the PhD student will aim to develop an understanding of the fundamental limiting processes seen in the devices, to ultimately improve power conversion efficiencies to above 15%.
