Measurement of Transmittance of Solar Battery Glass -Measurement of Transmittance of a Light Scattering Solid Sample-

Introduction

When measuring a solid sample with strong light scattering properties, using a 60 mm diameter integrating sphere can result in a change in photometric values at wavelengths where the detector is changed. We have recently developed a 150 mm diameter integrating sphere. Using this integrating sphere increases the number of times light reflects inside the integrating sphere so when light reaches the detector it is more uniform, and also results in a more optimized detector arrangement, reducing the change in photometric values that occurs at detector switching wavelengths. We introduce an example measurement of the transmittance of solar battery glass that is strongly light scattering, where the above described change in photometric values is prone to occur.
