Can solar photovoltaic panels generate electricity on rainy days?

In recent years, photovoltaic power generation has gradually entered rural households. Because the buildings in the rural areas are relatively low, with no shelter around them, and easy to connect to the grid, in recent years, in response to the call of the state, many farmers have also installed them on their roofs. A photovoltaic power generation panel. On the one hand, it is used by itself, on the other hand, the state is subsidized, and the electricity generated is integrated into the grid and there is a part of the income.
Solar cells were originally a phenomenon discovered by the French physicist Alexander Edmund Becquer (1820-1891) during his research-photovoltaics. Related to the photoelectric effect. Einstein successfully used quantum principles to explain this phenomenon and won the Nobel Prize.
The principle of photovoltaic power generation. When a photon irradiates a semiconductor material and collides with an electron in an atom, if the photon has enough energy, then the electrons in the outer layer of the atom will absorb energy, and if the electron absorbs enough energy, it will break away from the bondage. , Flee the metal. Become optoelectronics. Photovoltaic panels are made of silicon. Doping boron or phosphorous atoms in silicon will form p-type or n-type semiconductors. When a potential difference is formed on the contact surface, an electric current is formed. The photoelectric effect is a phenomenon in which light causes a potential difference between different parts of a non-uniform semiconductor or a combination of a semiconductor and a metal. It is the process of converting photons (light waves) into electrons and light energy into electrical energy; secondly, it is the process of forming voltage.
According to Planck's law, the energy of an incident photon is inversely proportional to its wavelength. Short-wavelength radiation occupies the purple end of the spectrum and includes ultraviolet radiation and gamma rays. On the other hand, long-wavelength radiation occupies the red end and includes infrared radiation, microwaves, and radio waves. Therefore, solar photovoltaic panels can also generate electricity on cloudy and rainy days, but due to current technical reasons, the efficiency of solar energy conversion is still very low, and the power generation efficiency on cloudy and rainy days is not as good as during the day.
Moreover, it is currently possible to generate electricity through friction in rainy days, and it will be converted into graphene for electricity generation on rainy days. Because there are sodium, calcium, and ammonium ions in rainwater, the positively charged ion layer will interact with the negatively charged electrons of graphene to produce a double-layer structure similar to a pseudo-capacitance. The potential difference between the two layers is large enough to generate voltage and current.
