Provided such a calibration is done, we conclude that it is feasible to follow the ASABE S.580.1 protocol using a low-cost lux meter for solar DNI measurements. The standard protocol requires measurements of direct normal irradiance and cooker pot temperatures every ten minutes.
Lux meters operate by using a sensor, typically a photodiode, which converts light into an electrical signal. This signal is then processed to calculate the illuminance. The accuracy of this process depends on the spectral response of the sensor and its calibration.
From the perspective of metrology, the use of a lux meter to obtain the light intensity is a typical indirect measurement method. The errors caused by different spectral response and light collection methods can accumulate and contribute to significant errors of the light intensity value.
In addition, the photode- tectors with the function of optical inte- grating sphere are used in lux meters, whereasthespectrometersuseadetec- tor (cosine collector) with a plane inci- dent window (Figure S5). From the perspective of metrology, the use of a lux meter to obtain the light intensity is a typical indirect measurement method.
The accuracy of this process depends on the spectral response of the sensor and its calibration. Modern lux meters are designed to closely mimic the human eye’s response to visible light, characterized by the V (λ) curve, ensuring that the device measures visible brightness effectively.
The LX1330B lux meter. Both the lux meter and the pyranometer use a silicon photodiode sensor, so they both have the same spectral response (which has a peak in the near infrared at about 950 nanometers). We wanted to know if a low-cost lux meter could be used as a reasonable substitute for a pyranometer for solar cooker performance tests.

Introduction to Solar Cells
Solar cells are the electrical devices that directly convert solar energy (sunlight) into electric energy. This conversion is based on the principle of photovoltaic effect in which DC voltage is generated due to flow of electric current between two layers of semiconducting materials (having opposite conductivities) upon exposure to the sunlight [].
