There are still some things to be overcome in solar photovoltaic power generation"Weaknesses"。Its main disadvantages are low conversion rate and large area. But these issues are continuing to improve as technology advances.

As we all know, the main function of solar cells is to convert light energy into electrical energy, and this phenomenon is called the photovoltaic effect. However, this makes us have many inconvenient factors when selecting raw materials for solar panels. It is necessary to take into account the light conductivity of the material and how the internal electric field is generated.

Not only do you need to absorb light, but you also need to look at its light guide effect. <>
