Solar cell efficiency represents how much sunlight is converted into electricity, with early solar panels having 8-10% efficiency compared to 40-55% for traditional energy sources. Advancements have increased solar cell efficiency to 15-22%, but this is still limited by the Shockley-Queisser limit of 33.7% maximum efficiency.
When it comes to renewable energy, the current grid infrastructure is often insufficient to support the transition to cleaner sources of power.

The problem with solar cell efficiency lies in the physical conversion of sunlight. In 1961, William Shockley and Hans Queisser defined the fundamental principle of the solar photovoltaic industry.
Dirt, debris, or bird droppings accumulating on the surface of the panels can also hinder sunlight absorption, resulting in reduced power output. Another potential cause of insufficient power generation is a faulty solar inverter, which converts the panels’ direct current (DC) generated into usable alternating current (AC).
Losses in solar cells can result from a variety of physical and electrical processes, which have an impact on the system's overall functionality and power conversion efficiency. These losses may happen during the solar cell's light absorption, charge creation, charge collecting, and electrical output processes, among others.
Another potential cause of insufficient power generation is a faulty solar inverter, which converts the panels’ direct current (DC) generated into usable alternating current (AC). Additionally, inadequate system sizing or incorrect panel orientation can impact power generation.
Shading is a primary culprit, where trees, nearby buildings, or other obstructions cast shadows on the panels, reducing the amount of sunlight they receive. Dirt, debris, or bird droppings accumulating on the surface of the panels can also hinder sunlight absorption, resulting in reduced power output.
