Can a convex lens generate electricity from solar energy

The results showed that the convex lens setup produced 1.94% more power, but only at around midday. The increase in power is due to the convex lens that focuses a greater amount of irradiance on the solar cell over the course of the day.. The results showed that the convex lens setup produced 1.94% more power, but only at around midday. The increase in power is due to the convex lens that focuses a greater amount of irradiance on the solar cell over the course of the day.. Assuming an ideal case, the energy from photons hitting solar cells is converted into electric energy as described by the equation: $RI^2t=W\equiv E=\hbar\nu$ where $\nu$ is the frequency of photons. Using a lens won't increase the frequency of photons, thus no extra electricity is generated.. A magnifying glass, also known as a convex lens, works by converging light rays to a single focal point, intensifying the energy contained within those rays. This property of magnifying glass has the potential to significantly increase the intensity of sunlight falling on solar panels..
