6 FAQs about [Deformation of photovoltaic panels leads to water leakage]

Can simulated lead leakage be reduced if a large-area perovskite solar panel is damaged?

The simulated lead leakage from damaged large-area perovskite solar panels treated with CERs can be further reduced to below 7.0 ppb even in the worst-case scenario that every sub-module is damaged.

What happens if a photovoltaic cell cracks?

Depending on the crack pattern of the larger cracks, the thermal, mechanical stress, and humidity may lead to “dead” or “inactive” cell parts that cause a loss of power output from the affected photovoltaic cell.

Can perovskite photovoltaic products be deployed with minimal PB leakage?

These findings strongly suggest that perovskite photovoltaic products can be deployed with minimal Pb leakage if appropriate encapsulation is employed. Lead leakage from damaged perovskite solar cells poses a challenge to the deployment of such technology.

How to reduce PB leakage of perovskite solar cells?

Recently, several Pb-adsorbing materials have been reported to treat the Pb-containing solutions or reduce Pb leakage of damaged perovskite solar devices 21, 22, 23. For example, a hole transport polymer of alkoxy-polytetraethylene glycol was also reported to chelate Pb ions and thus reduce Pb leakage of perovskite solar cells.

What happens if a PV module breaks?

Glass breakage leads to loss of performance in time due to cell and electrical circuit corrosion caused by the penetration of oxygen and water vapour into the PV module. Major problems caused by glass breakage are electrical safety issues. Firstly, the insulation of the modules is no longer guaranteed, in particular in wet conditions.

What happens if a PV module cracks?

First, PV cracks can allow moisture to enter the module, which can lead to the formation of hot spots when the moisture is trapped within the module. Second, PV cracks can create an electrical short circuit, which can cause an increase in electrical current and the formation of hot spots.
