Scientists in Japan put perovskite solar cells under the microscope, aiming to observe at the molecular level the degradation mechanisms that can occur during operation. Their findings offer an improved understanding of performance loss in perovskite thin films, as well as several pathways towards mitigation.

Scientists in the United States have conceived a new process to apply a low-cost organic pigment to perovskite solar cells. The new technique is claimed to increase the efficiency of the devices by around 1.2% and also to improve the cells’ stability.

Scientists in Portugal have proposed a new framework to simulate mismatch conditions at the cell level. They claim the tool is particularly suitable for simulations of small PV systems with few module strings.

Researchers in China are proposing a new technique to recover polyethylene glycol terephthalate (PET) and ethylene-vinyl acetate (EVA) in solar panels at the end of their lifecycle. The two materials represent around 15% of the total material in a wasted solar cell, with a share of 10% for EVA and 5% for PET, respectively.

Stanford scientists have used a robotic device with two nozzles to quickly produce thin films of perovskite. With these films, they have manufactured perovskite cells and modules with efficiencies of 18% and 15.5%, respectively. According to them, this technique may enable the production of perovskite modules at a cost of around $0.25 per square foot.

Scientists in the Netherlands are planning to build intelligent PV devices for energy and information applications. Their intention is to make this approach a new field of PV research, whose ultimate goal is enabling solar cells to communicate with each other and with other devices, ensuring that all the generated energy ends up exactly where it’s needed, especially in the urban environment.

The new technique, proposed by researchers in Pakistan, is claimed to estimate the voltage, current and temperature of a PV system without interrupting the power flow to load.

A group of German scientists has analyzed the possible trajectory of carbon nanotubes (CNTs) in photovoltaic research and industry and has suggested a roadmap to bring this technology closer to mass production. Despite a large number of challenges, the academics predicted a brilliant future for CNTs in PV applications, explaining that the barriers to their adoption are constantly being reduced.

Kibing Group and CECEP have announced plans to increase their PV glass and solar module capacities, respectively. China Energy Investment Corp is planning a 400 MW solar park in the Xinjiang Uygur autonomous region.

Lead-free perovskite-inspired materials still provide efficiencies that are too low for solar cells in outdoor environments. A British-Chinese research team, however, has demonstrated they have strong potential for indoor PV devices due to their ability to capture visible light.
