In the case of illumination (whether it is sunlight or the illumination produced by other illuminants), the battery absorbs light energy, and the accumulation of a different type of charge at both ends of the battery produces a "photogenerated voltage", which is the "photovoltaic effect". Under the effect of the photovoltaic effect, the two ends of the solar cell generate an electromotive force, which converts light energy into electrical energy, which is a device for energy conversion. Solar cells are generally silicon cells, which are classified into single crystal silicon solar cells, polycrystalline silicon solar cells, and amorphous silicon solar cells.
A Hammer Drill, also known as a percussion drill or impact drill, is a power Tool used chiefly for drilling in hard materials.It is a type of rotary drill with an impact mechanism that generates a hammering motion. The percussive mechanism provides a rapid succession of short hammer thrusts to pulverize the material to be bored, so as to provide quicker drilling with less effort. If a hammer drill's impact mechanism can be turned off, the tool can be used like a conventional drill to also perform tasks such as screw driving.
