Evaluation of Anti-Reflective Film on Solar Cell Using UV-2600 -Reflectance and Color Measurement-

Due to heightened concern over problems related to the environment and energy, attention is being focused on clean energy produced by solar cells. A variety of components are used to enhance the performance of solar cells, one of which is anti-reflective film. Antireflective film that is formed on the surface of a solar cell acts to prevent the loss of energy from incident l ight by suppres s ing i t s ref lect ion. Therefore, investigation of the reflective characteristics of this film is important. Here, we report on our investigation of the reflectance characteristics and color values of anti-reflective film using the UV-2600 with an integrating sphere mounted to allow measurement over a wider wavelength range,including the near infrared region.
