Cando Solar unveils frameless 450 W heterojunction PV panels with 22.6% efficiency
The Chinese manufacturer says its new frameless heterojunction panels rely on busbarless technology and 210 mm wafers. The new products also feature a temperature coefficient -0.29%/C and weigh only 12.3 kg.
MIT scientists build PV-driven desalination system that reacts to changes in sunlight
The proposed brackish water desalination system uses photovoltaic electrodialysis to enable direct-drive desalination at high production rates. It already operated for 6 months on real brackish groundwater and was reportedly able to use 94% of the extracted PV energy.
The impact of sodium, moisture on heterojunction PV module performance
Researchers in France have investigated heterojunction solar module reliability in damp heat environment and have found that sodium ions are the main source of degradation.
Rooftop PV installations could raise daytime temperatures in urban environments by up to 1.5 C
New research from India shows that rooftop PV system may have “unintended” consequences on temperartures in urban environments. Rooftop arrays, for example, may potentially lower nighttime temperatures by up to 0.6 C.
India adds 11.3 GW of solar module capacity, 2 GW of cells in H1 2024
India added 11.3 GW of solar module and 2 GW of cell manufacturing capacity in the first half of 2024, bringing the country’s cumulative production capacities to 77.2 GW for modules and 7.6 GW for cells, according to Mercom India.
Swiss startup offers organic PV-powered asset tracker
Truvami has launched an organic PV-powered asset tracker equipped with localization and sensor technology for battery-free use indoors and outdoors, targeting logistics and manufacturing applications.
Sinovoltaics tracks 78.8 GW solar module capacity in Southeast Asia
The latest supply chain map from Sinovoltaics tracks growth across Southeast Asia, with module capacity reaching 78.8 GW, and 58 production projects tracked.
Building-integrated photovoltaic system integrating PCM on sides
Scientists have designed a new building-integrated PV system that uses 30 mm of phase change material on each side of the wall. The array reportedly achieved superior thermoelectric coupling performance compared to reference BIPV systems without PCM.
Inverted perovskite solar cell based on lead carbanion achieves 25.16% efficiency
Developed by Scientists in China, the solar cell reportedly achieved the highest open-circuit voltage ever recorded for an inverted perovksite PV device. The lead carbanion layer was responsible for reducing defects at the interface bewteen the perovskite layer and the electron transport layer.
Will Indian solar manufacturers go back-contact to the future?
Indian PV manufacturers are looking beyond tunnel oxide passivated contact (TOPCon) solar. Back-contact (BC) devices are an enticing prospect but many feel the technology is not mature enough. Uma Gupta considers the cost, yield, and reliability challenges that BC solar has to overcome.
