if I take a huge magnifying glass and aim a beam of light from the sun on a solar panel , will it produce more energy ?

Short answer yes. Long answer “ish”
On earth we are limited to roughly 1.4kw per square metre.
So focusing more energy onto a cell that can handle it will work. But as the cell temperature increases, the power output decreases.
[concentrated PV](https://en.m.wikipedia.org/wiki/Concentrator_photovoltaics) was a thing for a while, but a path never really explored very much as the cost of cells declined and the requirement for mechanical tracking to keep the magnifying system in line with that sun, ment that its been left alone in favour of single axis movement and more panels.
Other issues like controlling and handling the output of the panel are big problems with cpv, as the control systems are not designed to handle the large voltage swings that the system will generate.
