Tóm tắt

Titan dioxide (TiO2) nanotube arrays với kích thước lớn có đường kính ngoài khoảng 500 nm đã được tổng hợp thành công thông qua quá trình anod hóa điện thế ở 180 V trong dung dịch điện phân đã qua sử dụng với sự bổ sung 1.5 M axit lactic. Kết quả cho thấy mảng nanotube TiO2 với đường kính lớn có khả năng tán xạ ánh sáng vượt trội, điều này có thể được sử dụng như một lớp tán xạ ánh sáng để nâng cao đáng kể hiệu suất của các tế bào năng lượng mặt trời nhạy cảm với phẩm nhuộm dựa trên hạt nano TiO2 từ 5.18% lên 6.15%. Khả năng tán xạ ánh sáng đáng kể này khiến mảng nanotube TiO2 đường kính lớn trở thành ứng viên tiềm năng cho việc quản lý ánh sáng trong các tế bào năng lượng mặt trời nhạy cảm với phẩm nhuộm (DSSCs).
