一開始透過量測發現了鈣鈦礦晶體中溴的表面空位，因此，本文先深入了解鈣鈦礦的晶體結構和光電特性。為了證實文獻上面的數據的真實性，本文也透過各種不同的實驗來去觀察實驗對鈣鈦礦晶體表面的影響。為了填補鈣鈦礦晶體的表面空位，本文以逆溫結晶法來成長不同Br-Cl比例的混合鹵化物鈣鈦礦單晶，並且透過觀察拉曼光譜進而了解不同鹵素對鈣鈦礦的影響。透過拉曼光譜可以看到晶體在不同峰值所對應到的意義有所不同，透過文獻的搜索及整理，本文有將各峰值所對應到的特性整理成表格，並且進一步探討比例改變對晶體特性的影響。最後，透過不斷的實驗，發展出本文獨特的手法成長單晶異質接面有機無機鹵化鉛鈣鈦礦晶體，透過不斷的嘗試及改良試著製造出新一代的光電元件。

At the beginning, the surface vacancies of bromine in the perovskite crystals were found by transmission measurement. Therefore, this article first understands the crystal structure and photoelectric properties of perovskite. In order to confirm the authenticity of the data in the literature, this article also uses various experiments to observe the effects of the experiments on the surface of the perovskite crystals. In order to fill the surface vacancies of perovskite crystals, this paper uses inverse temperature crystallization to grow mixed halide perovskite single crystals with different Br-Cl ratios, and understands the effect of different halogens on perovskites by observing Raman spectra. . Through Raman spectroscopy, we can see that the crystals have different meanings at different peaks. Through searching and sorting in the literature, this article has organized the characteristics corresponding to each peak into a table, and further explores the changes in the proportion of crystals to the characteristics of the crystals. influences. Finally, through continuous experiments, we have developed a unique method to grow single-crystal heterojunction organic-inorganic lead halide perovskite crystals in this article. Through continuous experimentation and improvement, we try to manufacture a new generation of photovoltaic elements.
