The bottom cell absorbs the red and infrared photons, while the middle cell absorbs the green photons and the top cell absorbs the blue photons. This spectrum splitting capability is the key to higher efficiency and reduction in light-induced degradation. n Using amorphous alloys of silicon and germanium adjusts the band gap energies n Absorb blue light well n Can be an automated, continuous production process n Lightweight, durable and flexible, making it ideal for portable solar cells Solar energy efficiency is closely related to the photons absorption from solar spectrum. The solar spectrum is electromagnetic radiation made up of a range of wavelengths. • Ultraviolet 0.04 – 400 nm ……9% • Visible 400-700 nm ……47% • Infra-Red 700-300,000 nm ……44% • X-Ray and Gamma Rays • Microwaves and Radio Waves Crystalline modules have good response in the red part of the visible spectrum. We see this type of light on clear winter days. The modules have a high relative outdoor efficiency when the sunlight intensity is high (1,100-1,250 W/m2). Thin-film amorphous Silicon (a-Si) modules have good response in the blue part of the visible spectrum. We see this type of light in the summer and on cloudy days (diffuse light). The modules have higher relative outdoor efficiency when the sunlight intensity is low (50-400 W/m2). Shading caused by bird dropping, water pudding, concentration of dust or dirt, ash zone and leaves can easily reduce the output of photovoltaic module and in serious cases even shut down the entire module completely. Therefore, the combination of construction and design of photovoltaic module is essential for the outdoor efficiency. A-Si modules, use unique material and technology, reduce output power loss caused by the shading and soiling effect to less than 4.5%.
