Technology and R&D

Scientists have simulated dozens of electron transport layer-free cell structures and have identified the optimal design with a Zr:In2O3 front transparent electrode, a CuSCN hole transport layer, and a NAN rear transparent electrode. They have also optimized its thickness and bandgap.

Scientists in Mexico have conceived a new solar module cooling tech that can reportedly improve PV power generation by up to 2%. The system uses nanofluids embedded in an aluminum single-channel attached to the back of the panel.

Researchers have designed a new tracking system that utilizes an arithmetic optimization-based PID controller. The proposed tracker uses two different sensor types – a UV sensor and a micro-electromechanical solar (MEMS) sensor. The first one calculates the intensity of UV radiation received from the sun, and the second one forecasts the sun’s path across the sky.

The solid-state battery developer announced it has achieved 800 cycles with its battery, marking significant progress towards commercialization. If this trend continues, the development holds promising potential for grid-scale projects.

Also on the rise: Harris names clean energy advocate Governor Tim Walz as VP pick. Atlanta Motorsports Park goes solar. And more.

Researchers have developed a quantum particle swarm optimization algorithm for maximum power point tracking that reportedly generates 3.33% more power in higher temperature tests and 0.89% more power in partial shading tests compared to conventional swarm optimization algorithms.

The Europa Clipper mission will send a craft the size of a basketball court to Europa, a moon considered a potential habitat for life.

PeroNova specializes in metal halide perovskite-silicon tandem solar cells made with its novel stability-enhancing interfacial treatment. It is targeting a range of applications including space and rooftop markets.

Researchers at MIT have enhanced the stability of Spiro-MeOTAD in perovskite solar cells, achieving over 1,400 hours of high-temperature testing with minimal degradation in a lower efficiency cell.

OptoGPT is a new algorithm that harnesses the computer architecture underpinning ChatGPT. Its creators say that it will enable researchers and engineers to design optical multilayer film structures for a wide range of applications, including solar cells.
