A new technology comes onto the market that it has managed to create solar panels for indoors with an efficiency of 42%. If you are surprised by the extensive quality control that solar panels will undergo from now on, you cannot miss the following. The solar panels They have become another element of the urban landscape. Its presence in the environment has become a symbol of modernity, savings and care for the environment.
The efficiency of the solar panels It is one of the most important features when choosing it. This is the ability to generate more energy in the smallest possible area. That is, the efficiency of the solar panels It measures the percentage of sunlight that hits the panel cells and is ultimately converted into electricity. It is very important that those who are purchasing a solar panel are clear about the difference between efficiency and performance.
The efficiency is equal to the ability of a solar panel to convert solar energy into electricity. That is, how ‘well’ the solar panel performs its function. The more performance you have, the more kWh of energy per watt of power. Being clear about the performance and efficiency of the panels is crucial for users with limited space on their roof.
42% efficiency with indoor solar panels: never seen before
Because of the importance of solar panels In the energy transition, a technology has appeared on the scene that promises an efficiency of 42% solar panels for indoors. China has reached this number indoors with a self-built cell. A reality that leads to it perovskite solar panels no silicon required. Efficiency has gone a long way perovskite cells to demonstrate his abilities.
He silicon-perovskite tandem It seemed like the necessary duo to get above 40% efficiency. However, new research without the presence of silicon has found the ‘perfect’ formula. A group of scientists has achieved 42% efficiency in indoor perovskite solar cells. The analysis performed in the Taiwan Ming Chi University of Technology tries to capture energy in less light or with artificial light. This type of light is usually found in residential environments and even in offices.
With this goal in mind, experts have developed a system to increase the efficiency of perovskite solar panels. The method used is based on self-assembling monolayers (SAM) that improve energy conversion in LED lighting environments. To ensure more stability, they used layers of nickel oxide (NiOx).
An improvement in the efficiency of solar cells has only been possible by optimizing the connection between NiOx and perovskite. To achieve this, they minimized non-radioactive recombination and improved interfacial contact, improving low-light performance.
Indoor solar panels: create a system to improve efficiency
Until now it was necessary to achieve an efficiency of almost 40% silicon-perovskite tandem. However, the group of Taiwanese scientists surpassed that percentage before them in the Huazhong University of Science and Technology, Chinathe first tests had already been carried out, achieving an efficiency of 28.8% without the use of silicon.
The weak point of perovskite solar cells, at a commercial level, has long been durability. In addition, specialists have discovered that applying a layer of hydrogen to the structure can improve its stability and resistance.
With this technology the solar panels for interiors they herald a new era, with an efficiency of 42%. A milestone for the sector that is almost as big as that of the new solar panels without installation.
