Solar energy and photokinetic energy have the same meaning, there is no difference, they just have different names.
There are two types of solar cells: high light type and low light type.
The low-brightness type can work under indoor lights or even candlelight. This type of battery is mainly used in watches, calculators and other micro-powered electronic products. That's why there is a saying that "it can work if there is light." The "photokinetic energy" mentioned here is just a gimmick for marketers to show that their electronic watches can work in dim light.
Kinetic solar energy is a promotion from Citizen. Many marketers have confused their own concepts and blame this concept on Casio. Promoting solar energy technology in Western Europe iscalled TOUGH SOLAR.
Detailed information
The different gray levels of substances in nature are the excessive changes from white to black and are also different chemical combinations between molecules of the substance. The spectrum of natural light contains many components of rays of different frequencies (from ultraviolet to infrared).
White objects absorb very little light, while black objects absorb most of the light, especially ultraviolet light in the spectrum, which has a very high absorption probability. The darker the color of the substance, the higher the thermal conversion efficiency of light energy. The higher the intensity of natural light, the higher the light energy conversion value of the substance.
Reference materials:
The low light performance of crystalline silicon cells is not good, and strong light irradiation is required to achieve the high efficiency of crystalline silicon cells.
Amorphous silicon has good low-light performance, and a little light can generate electromotive force and current! Therefore, it is necessary to choose cells with good efficiency in low light conditions. However, if you apply strong light to amorphous silicon cells, some of the light will be wasted (the conversion efficiency of thin-film cells is lower than that of thin-film cells). that of crystalline silicon cells, the same under strong light, crystalline silicon cells generate more electricity)
