NREL & CubicPV Push Perovskite Minimodule Performance to New Heights - CleanTechnica
A collaboration between the U.S. Department of Energy’s National Renewable Energy Laboratory (NREL) and Boston-based CubicPV has achieved a new record in perovskite minimodule efficiency, reaching a certified 24.0%. This marks the first time a U.S. team has set a record in this category. The minimodule, composed of multiple interconnected cells, was fabricated through combined efforts at both organizations, leveraging their complementary expertise. NREL focuses on advancing manufacturing, durability, and efficiency of perovskite-enabled tandem solar cells, while CubicPV specializes in tandem devices that layer perovskites on silicon to capture more photons and reduce energy costs. Perovskite solar technology is notable for its low-temperature, ink-based or vacuum coating production processes using earth-abundant materials, offering a promising alternative to traditional silicon solar cells. While small-scale perovskite cells have demonstrated high efficiency, scaling up to larger-area devices with improved durability remains a key challenge for commercial viability

Researchers in China have developed an innovative approach to significantly improve bifacial perovskite solar cells (Bi-PSCs), achieving a record power conversion efficiency (PCE) of 23.4% while dramatically reducing photon loss—a key factor limiting these cells’ performance. By identifying photon loss as the primary cause of performance degradation, the team introduced a high-quality thick-film deposition method that regulates perovskite crystallization dynamics. This method employs a multifunctional additive, 1-ethyl-3-guanidinium thiourea hydrochloride (EGTHCl), to control nucleation and crystallization in highly concentrated precursor solutions, resulting in dense, uniform, and defect-free perovskite films. The enhanced Bi-PSCs not only reached a record efficiency but also demonstrated remarkable stability, retaining over 80% of their initial performance after more than 2,000 hours of continuous light exposure. This advancement addresses the inherent design challenge of bifacial cells, which use semi-transparent rear

Scientists at National Yang Ming Chiao Tung University in Taiwan have developed a new type of perovskite solar cell (PeSC) that achieves a remarkable 38.7% power conversion efficiency (PCE) under low indoor lighting conditions of around 2,000 lux, typical of office environments. While traditional silicon solar cells perform better under direct sunlight (up to 26% PCE), these perovskite cells excel in dimmer settings, producing energy even on cloudy days or indoors. The PeSCs are thin, lightweight, flexible, and semi-transparent, offering advantages over rigid and heavy silicon panels, which are limited to flat, durable surfaces. The researchers enhanced the solar cells by adjusting the bandgap through molecular composition changes in the perovskite layers, enabling efficient absorption of indoor light—a capability not achievable with silicon cells. This breakthrough suggests potential applications for powering small devices in indoor or low-light environments, reducing reliance on traditional power sources and expanding solar technology use beyond outdoor
