Perovskites are easier to manufacture using fewer steps and lower temperatures than silicon cells, making them more eco-friendly. The lightweight nature and flexibility of perovskite solar cells make them suitable for a wider variety of applications than silicon.

However, perovskite solar cells degrade more rapidly than silicon cells, hindering their commercial use. Researchers are currently attempting to improve their stability and scalability. A recent collaborative study identified a strategy to enhance the lifetime of perovskite solar cells by 66% while reaching efficiencies of over 23%.

2. Kesterite Solar Cells

Kesterite is a promising light-absorbing material that can be a game-changer in lower-cost thin-film solar cells. Kesterite cells include common, earth-abundant elements like zinc, copper, selenium, and tin, making them more environmentally friendly than silicon-based cells.

In a study published in May 2024, researchers fabricated a kesterite solar cell with a total-area cell efficiency of over 14%. The findings present a significant advancement in kesterite solar cells, which usually feature limited performance caused by defect-induced charge losses.

According to the researchers, multinary alloying can help suppress deep defects in kesterite solar cells, allowing them to meet the requirements of low-cost, large-scale industrial manufacturing.

3. Organic Photovoltaic Solar Cells

Organic photovoltaic (OPV) cells are a rapidly emerging solar technology that is flexible, lightweight, and cheap to produce. They feature semiconductor polymers that convert sunlight into electricity and are eco-friendly and more sustainable than silicon-based cells.

OPV cells show promising prospects for integration with wearable smart electronics, clothes, and eco-friendly buildings. They’re especially attractive for the building-integrated market because they can make efficient, transparent devices and come in any colour.

However, OPV cells still face a few hurdles, including enhancing scaling efficiency on large-area modules and improving the lifetime of the solar cells.

4. Smart Solar Panels

The increasing integration of solar panels with smart technologies like artificial intelligence (AI), sensors, and Internet of Things (IoT) capabilities has revolutionised the solar industry. Such integrations allow better maintenance, monitoring, and optimisation of solar panel performance for improved effectiveness and efficiency.

AI and smart technologies can leverage automation and data analytics to estimate panel energy production in different climate conditions. They can track and analyse weather data, such as cloud cover, to predict solar output and adjust the position and orientation of your panels to maximise energy capture.

AI-powered designs also help optimise panel installations by combining predictive algorithms with real-time data analysis and automated control systems. Combining AI and smart technologies with solar panels has significant potential. However, collaborative efforts between AI researchers, solar experts, and data scientists are necessary to create reliable AI solutions tailored for solar panels.

5. Bifacial Solar Panels

Bifacial solar panels improve energy generation by capturing sunlight from both module sides. The innovative design allows the panels to use the sunlight reflected by various surfaces, including water, the ground, or nearby structures, resulting in an increased electricity yield.

Bifacial solar panels are ideal for areas with high reflectivity, such as sandy or snowy environments. Recent advancements include improved cell designs, with the International Energy Agency (IEA) reporting that they can allow rear cells to achieve efficiencies of over 90% compared to the front side.

Tracking systems can also help enhance the performance of bifacial modules by adjusting the orientation of the panels to follow the sun’s path. However, challenges like the complicated system design of bifacial modules and effectiveness in extreme weather must be addressed.

6. Solar Paint

Solar paint, also called photovoltaic paint, is a type of coating that generates energy when exposed to sunlight. It can potentially make solar power more cost-effective, accessible, and visually appealing.

Unlike traditional panels, solar paint eliminates aesthetic and spacing concerns. It can be applied on exterior surfaces to transform roofs, walls, or windows into energy-generating assets. Solar paint is still under development using technologies like perovskite, quantum dots, and hydrogen.

Solar paint is still in its early stages but shows great promise. Research institutions and researchers like the Royal Melbourne Institute of Technology (RMIT) and the University of Toronto are racing to bring commercially viable solar paint to the market.

7. Floating Solar Photovoltaics

Floating solar photovoltaic (FPV) panels, also called floatovoltaics, are a new renewable energy option with great potential. FPV modules are solar panels that float on bodies of water using raft-like structures. Water bodies include industrial ponds, irrigation canals, quarry lakes, water reservoirs, and near-coastal areas.

It’s suitable for areas with high electricity demand but limited land availability, such as densely populated regions. Such systems can help curb evaporation while ensuring the panels stay cool for maximum efficiency. Recent studies show that FPV systems can generate 0.6% to 4.4% more energy with efficiency improvements ranging from 0.1% to 4.45% over land-based counterparts.

However, various challenges must be addressed to realise the full potential of FPVs. These include complexities in design and installation, safety concerns, and potential maintenance considerations.

8. Advanced Thin Film Solar Panels

Thin film solar panels have traditionally been less efficient than standard solar panels, but this is changing thanks to advancements in solar technology.

Researchers are now using materials like Copper Indium Gallium Selenide (CIGS), Cadmium Telluride (CdTe), Gallium Arsenide (GaAs), and organic photovoltaic (OPV) cells instead of the commonly used silicon to improve efficiency. Several layers of the materials are deposited onto substrates like glass, plastic, or metal.

Thin film PV modules can be made lightweight, bendable, and even transparent, enabling integration into various surfaces and applications. In one study, researchers developed ultralight, thin, and flexible solar cells that are easily applicable to any surface.

The study demonstrated that thin solar cells can be made using scalable printing processes and are highly efficient, generating 18 times more power than conventional solar panels. The advanced thin-film cells have vast potential in portable and wearable devices, consumer electronics, building-integrated photovoltaics, and transportation.

9. Anti-solar panels that Work at Night

Recent advancements in thermoelectric technology have enabled the development of anti-solar panels that generate electricity in the absence of sunlight. The innovation can complement conventional solar panels and help bridge the energy gap during nighttime hours.

The panels work by radiating heat to take advantage of the temperature difference between the panel and the colder outer space. The temperature difference generates a current as electrons within semiconductors get knocked loose.

Researchers are ironing out the kinks for anti-solar power cells with studies showing a rooftop proof-of-concept that can theoretically generate 2.2 watts per square meter and produce 12 times more energy than previous designs. Although they’re still in their infancy, anti-solar panels have great potential and can help overcome the inability to generate power at night.
