Multi-junction (MJ) solar cells arewith multiplemade of . Each material's p–n junction will produce electric current in response to different . The use of multipleallows the absorbance of a broader range of wavelengths, improving the cell's sunlight to electrical energy conversion effici. Multi-junction solar cells are capable of absorbing different wavelengths of incoming sunlight by using different layers, making them more efficient at converting sunlight into electricity than single-junction cells.

Multi-junction solar cells are capable of absorbing different wavelengths of incoming sunlight by using different layers, making them more efficient at converting sunlight into electricity than single-junction cells.

Multi-junction (MJ) solar cells are solar cells with multiple p–n junctions made of different semiconductor materials. Each material's p–n junction will produce electric current in response to different wavelengths of light. The use of multiple semiconducting materials allows the absorbance of a broader range of wavelengths, improving the .

Materials scientists have developed a highly efficient thin-film solar cell that generates more energy than typical solar panels, thanks to its double-layer design.

In the multijunction solar cell structure, two [24] or more [25] solar cells are stacked on top of each other. The multijunction solar cell approach means that the absorber layer in each component cell can be tailored to a specific part of the solar spectrum.

To boost energy yield, researchers and manufacturers are looking at bifacial solar cells, which are double-sided to capture light on both sides of a silicon solar module—they capture light reflected off the ground or roof where the panels are installed.

6 FAQs about [Why do photovoltaic panels need to be double-layered ]

Are thin film solar cells better than crystalline solar cells?

Credit: Akhlesh Lakhtakia, Penn State Solar cells have come a long way, but inexpensive, thin film solar cells are still far behind more expensive, crystalline solar cells in efficiency.

What are the different types of photovoltaic cells?

There are four main categories of photovoltaic cells: conventional mono- and poly- crystalline silicon (c-Si) cells, thin film solar cells (a-Si, CIGS and CdTe), and multi-junction (MJ) solar cells.

How does a photovoltaic panel produce electricity?

In a photovoltaic panel, electrical energy is obtained by photovoltaic effect from elementary structures called photovoltaic cells; each cell is a PN-junction semiconductor diode constructed so that the junction is exposed to light and unpolarized.

How do photovoltaic cells work?

Traditional photovoltaic cells are commonly composed of doped silicon with metallic contacts deposited on the top and bottom. The doping is normally applied to a thin layer on the top of the cell, producing a p–n junction with a particular bandgap energy, Eg.

How do two materials work in a solar cell?

These two materials work in a solar cell because the structure of both materials is the same. They have roughly the same lattice structure, so they can be grown one on top of the other, and they absorb different frequencies of the spectrum so they should increase efficiency, according to Lakhtakia. "It was amazing," said Lakhtakia.

Why are monofacial HJT solar cells better than heterojunction solar panels?

This three-step process is the reason why monofacial HJT solar cells have achieved solar efficiencies of up to 26.7%. Heterojunction technology is based on traditional c-Si panels, improving the recombination process and other major flaws.
