More info on panels that generate electricity on rainy days
The College of Nanosciences and Technologies at Soochow University in China has developed a combined solar panel / triboelectric nanogenerator (TENG), capable of generating electricity on rainy days. TENG is based on the process that certain materials become electrically charged after rubbing contact with a different material.
The creation of energy comes from the power generated by the friction between raindrops and solar energy.
On rainy days, TENG will operate, transmitting energy to the solar panel via PEDOT: PSS, replacing the solar panel that collects energy from the sun on sunny days, since the two transparent polymer layers would not block sunlight.
The device is still experimental, with a short-circuit current of 33nA and an open circuit voltage of 2.14V.

Editor's note Having a panel that creates energy in sunny and rainy weather is a dream, as it ensures almost regular production in summer and winter, with even night-time production in case of rain. Even though it will be much more expensive due to its novelty and its more numerous components, we can be sure that there will be a demand for this type of panel.
