Breakthroughs in Perovskite Solar Cells
Increased Stability and Efficiency
Recent studies have indicated major breakthroughs in enhancing the stability and efficiency of perovskite solar cells. One notable achievement is the significant improvement in the long-term stability of tin-lead perovskite solar cells (PSCs), achieved by a research team at UNIST.
They developed efficient and stable tin-lead PSCs using a dual-functional cathode interlayer. These cells demonstrated an impressive efficiency of 23.21% and retained over 81% efficiency after 750 hours of operation at 60°C.
Enhanced Power Conversion Efficiency
Perovskite tandem solar cells, combining traditional silicon with perovskites, have reached experimental efficiencies of around 26%, while perovskite-only cells have achieved efficiencies of about 33% in laboratory settings.
These cells can utilize more of the solar spectrum by absorbing different wavelengths of light than silicon cells, thus producing more electricity per cell.
Innovations in Bifacial Solar Modules
Indoor Bifacial Solar Cell Technology
At CES 2024, Ambient Photonics introduced its first bifacial solar cell, the Low-Light Indoor Bifacial Solar Cell. This cell is capable of harvesting indoor light energy from both its front and back sides, potentially eliminating the need for batteries in connected devices.
Ambient Photonics claims its photovoltaic can generate up to three times more power than conventional technology, with the front side delivering 100% power and the back side contributing at least 50% energy.
Growth of the Bifacial Solar Market
The bifacial solar module market is set to grow tenfold by 2024. Bifacial modules generate electricity from both the front and the back sides of the panel, increasing the energy yield.
Wood Mackenzie predicts that by 2024, annual global bifacial module capacity will exceed 21 gigawatts, accounting for 17.2 percent of the total installed capacity. The affordability and ease of manufacturing these modules are key factors driving their market growth.
