An Overview Of The Quantum Dot Solar Cell

quantum dot solar cell

A quantum dot solar cell is simply a solar cell style that uses quantum dots as an absorbable photovoltaic component. It attempts to substitute more extensive bulk materials like copper, indium, or cadmium, all of which are less efficient and expensive than quantum-dots. Quantum dots, which are tiny dots of impurities, are found in many solar panels’ materials. These impurities can be combined with boron to create an even more efficient absorbent.

Ways To Improve The Efficiency Of Quantum Dots

Researchers have proposed many ways to improve the efficiency of quantum dots in solar cells. They have experimented with creating devices that allow them to control how the beads catch the light. One approach uses phosphorus instead of calcium, creating an increased inefficiency. Another makes use of aluminum oxide, an ingredient that has already been proven to have efficiency-boosting qualities. Still, another combines sodium bicarbonate with aluminum oxide to create a compound that has proven to be just as efficient but doubles existing compounds’ efficiency.

Researchers Claim

Because of this progress, some researchers have claimed that they have discovered a way to make a quantum dot solar cell that is four times more efficient than what is currently available on the market. This would put the new cell beyond just being a competitor, however. It would be able to replace solar cells now in use completely. If this claim is valid, then it would revolutionize the solar industry. Even if it is not the final step, the potential to dramatically increase the efficiency of many different solar cells is something that scientists have been talking about for years, and that is good news for the consumer.

Power Plant Working

The other part of the story involves the way that such a power plant might work. There are two main ways that these plants are designed to work: either using solar cells that are constructed into a tower or using photovoltaic materials that are installed on a roof. These methods have their advantages, although installing a single photovoltaic panel can lead to a power plant being more efficient than a combined system. With several layers of photovoltaic materials up top, each layer would absorb and then send the right amounts of energy to the bottom layers, where the quantum dots would then convert the energy into electricity.

Photovoltaic Material Layers

Each of the layers of photovoltaic materials is necessary because a single cell’s efficiency has a lot to do with how much usable power that the cell can produce. To maximize this useful output, a series of them is needed. However, it can get complicated if one or two layers are unable to do their job correctly. Usually, when two layers of material fail to do their jobs properly, the result is less than perfect output. Quantum dots are used to solve this problem. Using a series of quantum dots, the efficiency of a single layer of photovoltaic material can be improved, which allows it to produce a higher amount of usable electricity.

Cell’s Efficiency Improvement

While the efficiency of a single layer can improve a cell’s efficiency, there are still other layers that can contribute to the overall efficiency of a photovoltaic panel. Using several layers of quantum dots, even the failure of one of them will not cause a problem. The bigger problem becomes when only one of the layers fails. It is nearly impossible for even the most significant and most efficient photovoltaic cells to outlast all the individual layers’ combined effect. Lacking the ability to make use of multiple layers of quantum dots, the average photovoltaic cell will be unable to keep up with today’s society’s needs, and as a result, will slowly but surely become obsolete.


Using multiple layers of photovoltaic cells, which are often referred to as “catalysts,” allows for the integration of several different technologies, all of which contribute to the final product’s efficiency. For instance, by combining multiple layers of colloidal quantum dots, you can significantly increase a single layer’s efficiency. By arranging the alignment of the colloidal sulfur in the cells in such a way as to allow for their mutual interactions with one another, the efficiency of a single layer cell can also increase. In doing so, it can produce more electricity from each cell. All of this contributes to the final product’s reliability, allowing the average homeowner to save an incredible amount of money on their power bill.

Summing Up

While utilizing DSSC in its various forms has been around for almost thirty years, only recently has the widespread use of this technology began to be seen. DSSC is an organic semiconductor, which means that it is made of an organic base metal plane and a crystal structure. In using quantum dots, one of the benefits is that they are 100% pure and can therefore be used in place of other substances. However, many consumers have expressed concern over the purity of DSSC, mainly when dealing with DSSC based solar panel systems. Many customers have requested that DSSC be mixed with inert gas, thus eliminating any chance of creating a risk-free electricity production system.
