| 中文摘要 | As poly-CSiTF (Crystalline Silicon Thin Film) solar cells have the capacity of reducing their cost, it has become one of the hotspots in the research field of solar cells. We will focus on the low cost, uninterrupted preparing technology of polycrystallinesilicon materials SSP (Silicon Sheet from Powder Process) process and thepreparation technology and performance analysis of poly-CSiTF solar cells based on SSP substrate.This thesis will briefly introduce the developing situation and fundamentals of crystalline silicon thin film solar cells and their substrate materials, and illustrate the SSP technology in our Solar Energy Laboratory in details. Othordoxy design method of experiments is applied to optimize technical parameters of SSP process so that the electrical and photovoltaic performance of SSP can be improved. Modern analyzing methods such as SEM, XRD, AES and four probe resistivity etc. are proceeded to study photovoltaic characteristics of SSP and expatiate the imperfection of SSP's microstructure, especially the three main functions of SSP which are device supporting, applying back surface field (BSF) and crystal growing seed, respectively..Purity is one of the elemental factors affecting photovoltaic characteristics of polycrystalline silicon materials. In order to discuss the practical possibility of SSP as poly-CSiTF solar cells substrate material and the influence of defect states such as grain boundaries (GB) to impurity segregation phenomenon, SSP materials by different low cost silicon powders are prepared to measure and analyze their configuration and photovoltaic performance. Based on these results, technical reqiiirements for low purity and low cost SSP substrate materials are brought forward.Besides the above, experiments of preparation and performance analysis of poly-CSiTF solar cells based on SSP substrate (conversion efficiency has been up to 6.05%) are also discussed. As a result, final suggestions and optimization scenario for SSP technology and poly-CSiTF based on SSP are brought forward which could be experimental and theoretical foundations for mid-scale experiments, and a practical cost reducing industrialization route for poly-CSiTF solar cells is capable to be supplied. |
