Russian scientists unveil new manufacturing process for III-V solar cells
Researchers have integrated A3B5 semiconductors on a silicon substrate in a prototype solar cell and claim the technique could enable the production of III-V solar cells with conversion efficiencies of around 40%.
Perovskite production without the side-effects
Chemists from Russia’s RUDN University have developed a series of compounds based on methylammonium iodide and iodine which they say could be used to make perovskite solar devices without toxic solvents. That would enable perovskite cells to be manufactured without chemical by-products.
Parent company of Algerian module maker Condor reported to have filed for insolvency
The electronics manufacturer has a 130 MW capacity module production facility.
Silicon heterojunction solar cell hits 23.5% efficiency with new hole-selective contact
Researchers from Switzerland’s École Polytechnique Fédérale de Lausanne have used molybdenum oxide as the hole-selective contact in an heterojuction silicon cell. The scientists claim the compound can compete with traditional contacts despite a lower level of optimization.
MIT researchers say PV innovations should be deployed in niche markets first
Solar module manufacturers should begin testing new technologies in higher-value niche markets, say scientists at the U.S. institution. For example, bringing perovskite technology directly to the mainstream market remains prohibitive in terms of initial investment but segments such as building-integrated PV or microelectronics devices may offer better routes to commercial maturity.
Hunting hidden electricity in crystalline solar cells with new encapsulation technique
Korean researchers claim it is possible to extract more than 10% of ‘hidden electricity’ in crystalline solar cells using a new encapsulation process based on poly‐dimethylsiloxane coatings and a three-dimensional module structure. Compared to EVA films, the new coating is said to avoid cutting off short-wavelength light.
Innovative PV modules at Intersolar San Diego
In sunny San Diego for Intersolar 2020, we’re seeing a new idea for tracking rooftop solar modules, diodes moving to cell level, two types of building-integrated solar products and some solar hot water.
Fraunhofer ISE researchers develop bifacial hybrid HCPV module with output of 326 W/m2
The EyeCon module has a hybrid power output of 326 W/m² or a bifacial efficiency of 28%, calculated with the available global plus backside irradiance. According to the research team, the silicon cell generates between 23 and 42 W/m² of additional power when the diffuse irradiance component increases from 8 to 30%.
Canadian Solar signs 1.2 GW supply agreement with Lightsource BP
The Chinese-Canadian module manufacturer will supply panels to the U.K.-based developer over several years. The modules are destined for projects in the United States and Australia.
Ricoh launches solar cell for indoor applications
The Japanese electronics company has produced a solid-state, dye-sensitized solar cell for integration into sensors and consumer electronics. The company says the device can generate electricity from indoor light.
