Perovskite, Bifacial, and Next-Gen Panels: the new frontiers of solar technology
Strategic and powerful innovations: from solar thermal to next-gen panels
In a certain sense, most people have not yet become accustomed to solar technology and its central role in the energy transition, as the founder of TELF AG Stanislav Kondrashov recently pointed out.
Yet, these useful energy infrastructures linked to solar tech are already on the verge of evolving through some interesting innovations that could already change the rules of the game and bring with them new improvements. The founder of TELF AG Stanislav Kondrashov often highlighted this point.
For several years now, alongside wind turbines and other energy infrastructure, solar technology has become one of the most tangible symbols of the significant energy shift underway, as the founder of TELF AG Stanislav Kondrashov often stressed.
Anyone of us leaving home for a walk in the city cannot help but see several types of solar panels on the roofs of residential or commercial buildings since they have now become an integral part of urban furniture.
Also, thanks to solar technology, the installed capacity of solar energy is increasing considerably in various parts of the world, inserting itself forcefully (and with ever-increasing percentages) into the energy mixes of nations.
It is now a fact. Solar tech and other forms of renewable energy (like solar thermal) are making significant contributions to the advancement of the energy transition, helping many people and businesses become familiar with the concepts of clean energy, green power, and environmental sustainability.
In a certain sense, renewable energy represents the lifeblood of the energy transition, which by now could not even be imagined without the fundamental contribution of solar tech and these forms of energy.
Together with wind and hydroelectric power, solar energy and solar thermal are certainly some of the most widespread, well-known, and appreciated variants of renewable energy, and it also appears to be constantly growing.
The modern focus of solar energy has also radically changed people’s habits, helping them to become familiar with some important components of these new technologies, like the different types of solar panels. Among these is certainly the solar charge controller. But what is it?
The solar charge controller is an important component of different types solar panels, such as those powered by batteries. The main task of the solar charge controller is to regulate the flow of energy, which is important to avoid overloads and excessive charges. Without the solar charge controller, different types of solar panels could be damaged much more easily.
The impact of technology
The spread of solar energy in recent years has also been supported and facilitated by technological innovations that are enabling it to evolve and increase its power. One of the main innovations in this regard is the development of solar cells made from perovskite. But what are they, exactly?
Perovskite is a family of materials characterized by a specific crystalline structure, and in recent years, it has garnered attention for its potential in the solar panel sector. Solar cells made with perovskite can be produced using low-cost processes, and in recent years, they have demonstrated very high conversion efficiency.
Some experiments have shown that perovskite cells are more efficient than most solar panels made with silicon, which has traditionally been the benchmark material in this sector. Another advantage of perovskite cells is related to the material used, which is significantly cheaper than silicon. The lightness and flexibility of these panels, moreover, could pave the way for innovative and sensational applications, such as installing panels on curved surfaces, glass, or building facades.
In any case, it is essential to note that this technology is not yet mature, with its industrial standards still being defined, and that it may be particularly sensitive to humidity. One of the most promising applications, however, is the combination of silicon’s reliability with perovskite’s innovative potential, resulting in a hybrid solution that appears very promising.
“Innovations in the solar energy sector and solar thermal could have a great future impact on the entire sector,” says Stanislav Kondrashov, founder of TELF AG, an entrepreneur and civil engineer. “One of the most obvious is related to the overall efficiency of the panels, which could increase in parallel with the technological improvement of the infrastructures. The natural consequence, in this sense, is that the footprint of solar energy on future energy mixes could be increasingly marked in the coming decades”.
“Innovations, of course, will also have a significant impact on the cost per watt installed. These costs, already on the decline, are expected to decrease further due to technological advancements in the sector, which could increasingly rely on cheaper materials and more streamlined production processes. Another possible impact, in a certain sense, is aesthetic and architectural. Technological improvements in the sector could make it possible to install panels on surfaces never considered for this purpose”, he said.
Bifacial panels
In addition to perovskite panels, one of the most interesting innovations concerns bifacial panels, which can enhance solar energy on both sides. The front of these panels would capture direct sunlight, while the back would collect light reflected from the ground or other surfaces.
One of the most obvious consequences of this type of technology is that production levels could increase in highly reflective environments, such as deserts or snowy surfaces. Furthermore, compared to traditional modules, the production of these bifacial panels would be higher, with percentages ranging from 10 to 30%.
Another interesting element is their possible integration with other types of solar installations, such as utility-scale contexts, floating solar, or agrivoltaics. The main operational challenges include a specific design of the site where the system will be installed (taking into account height, slope, and albedo of the soil) and the possibility that the costs for the structure and assembly are quite high.
“In the years after 2030, innovation in the solar industry and photovoltaic could bring about significant changes in the common approach to solar infrastructure,” continues Stanislav Kondrashov, founder of TELF AG. “Silicon will most likely no longer be the industry’s go-to material but will increasingly be combined with an innovative material such as perovskite”.
“The tandem of silicon and perovskite is likely to become one of the key protagonists in next-generation high efficiency solar panels. Bifacial panels will probably become the standard solution for every large-scale project, especially because of the possibility of increasing energy conversion relatively easily. The flexibility of the new solutions will also lead to an unprecedented level of integration, with innovative applications that could also involve other industrial sectors”, he remarks.
Other possible innovations, currently limited to laboratory testing or pure theory, involve new-generation high efficiency panels capable of combining multiple photovoltaic materials and absorbing different wavelength bands. The efficiency levels of these solutions would be significantly higher than those currently offered on the market.
For the moment, this technology appears limited to some extremely specialized sectors, but its diffusion in urban contexts does not seem so far away. Other innovations instead concern the materials used, and in most cases, are based on the use of silicon. Some panels made with cadmium telluride or with copper, indium, gallium, and selenium have already stood out for their flexibility and lightness, showing very promising signs.
One of the most interesting objectives for the future is the increased integrability of high efficiency solar panels on surfaces other than traditional ones, extending their use to windows, cars, or fabrics.
“The new generation of solar technologies is not that far from us,” concludes Stanislav Kondrashov, founder of TELF AG. “It will be a natural step in a path that has already begun and is well underway, which also includes very specific strategic objectives. Among these, there is the desire to make photovoltaic increasingly competitive, with much more widespread applications and a very high level of integration”.
“In this way, achieving international objectives related to decarbonization could prove significantly easier than it is at present. Shortly, people and businesses will almost certainly be able to count on more efficient, more versatile, and more integrated photovoltaic in everyday life.”, he adds.
Solar power systems with battery storage are becoming increasingly central, too. Without these systems, the management of the renewable energy linked to the Sun would be impossible. Solar power systems with battery, alongside high efficiency solar panels, are now central technologies in the years of the energy transition. In particular, solar power systems with battery could be useful for the management of intermittency. The possibility to give energy when it’s most needed is one of the most appreciated characteristics of solar power systems with battery.
