Batteries and Fuel Cells

A battery is a galvanic cell that is used as a source of electrical power for specific applications. Modern batteries exist in a multitude of forms to accommodate various applications, from tiny button batteries such as those that power wristwatches to the very large batteries used to supply backup energy to municipal power grids. Some batteries are designed for single-use applications and cannot be recharged (primary cells), while others are based on conveniently reversible cell reactions that...

P-N junction

P-N junction

A p-n junction is formed when p-type and n-type semiconductor materials are joined together. At the interface of the p-n junction, holes from the p-side and electrons from the n-side begin to diffuse into the opposite sides due to the concentration gradient. This diffusion of carriers leads to a region around the junction where there are no free charge carriers, known as the depletion region. The charge density within the depletion region for the n-side and p-side can be described by the...

Area of Science:

Materials Science
Environmental Science
Renewable Energy

Background:

Perovskite solar cells offer high efficiency but face commercialization hurdles due to toxic lead (Pb²⁺) and iodine release.
Environmental hazards from lead and iodine leakage impede the widespread adoption of perovskite solar modules.

Purpose of the Study:

To develop an integrated solution for environmental protection and material recycling in perovskite solar devices.
To address the key challenges hindering the commercialization of perovskite photovoltaics.

Main Methods:

Development of dual-function adsorbent-porphyrin-modified whitlockite nanocomposites (WH&Por) for simultaneous capture of lead ions and iodine species.
Implementation of a semi-closed loop recycling process for recovering high-purity lead iodide (PbI₂) from perovskite waste.
Testing the environmental safety performance under mechanical damage and evaluating the efficiency of recycled materials.

Main Results:

WH&Por nanocomposites effectively prevented lead and iodine leakage, even under severe mechanical stress (0.25 mg/cm² loading).
A recycling process achieved up to 96.9% recovery yield of high-purity PbI₂.
Devices fabricated with recycled PbI₂ showed comparable power conversion efficiencies to pristine devices, with residual Pb²⁺ below 10 ppb.

Conclusions:

The proposed WH&Por nanocomposite offers a robust integrated
protection-recycling
solution for perovskite solar cells, enhancing environmental safety.
This approach significantly reduces environmental risks and promotes a circular economy in perovskite photovoltaics.
The study provides a viable pathway for the sustainable commercialization of perovskite solar technology.
