GCell is the first choice for electrical engineers and product designers seeking a indoor Dye Sensitized Solar Cells (DSSC) that are flexibleÂ and boast superior low light performance. With GCell any light source becomes an energy source.
GCell can be incorporated into a wide range of indoor and portable products to provide power for refuelling rechargeable batteries, super capacitors or directly powering almost anything that uses a AA-cell disposable battery.
The output of GCell, like all other indoor solar cells, will differ depending on the light source to which they are exposed. This is because photo electric conversion efficiency (PCE) changes with the respect to the wavelength and intensity of the light.
The absorption spectra of GCell is 390-700 nm. The peak absorbance is between 500-550 nm.
Using GCell indoor Dye Sensitized Solar Cells
GCell is constantly energy scavenging even with indoor low light conditions. Illumination indoors is usually specified in Lux. This unit of illuminance is based on the spectral response of the human eye ie the visible light.
GCell works in a wide range of indoor lighting conditions from low light conditions (50 lux) to dimly-light living rooms (200lux) through to brightly-lit supermarkets (1000lux).
GCell has been attuned to indoor lighting conditions to provide improved power density. The spectral response of GCell is similar to that of the human eye, infrared and ultraviolet have little effect to its energy harvesting capabilities.
Angle of incidence
Indoor light is already diffused particularly with florescent tubes, so in affect the light doesnâ€™t have an angle. Due to the diffusion there is no real effect on performance based on the angle and only the light level on the surface will affect the performance of GCell.
Even in outdoor lighting conditions the photoelectric conversion efficiency (PCE) of GCell has no dramatic changes according to the light angle. Adjusting the incident angle from 60Â° to 90Â° will not reduce the efficiency by more than 5%.
