South Korean researchers have developed a hybrid tandem solar cell based on quantum dots and organic bulk heterojunction (BHJ) photoactive materials. They claim that the cell could reach an efficiency rate of around 15% if they continue to reduce energy losses in the quantum dot cell and enhance near-infrared absorption.

Clean Power Published on February 28th, 2020 | by Steve Hanley February 28th, 2020 by Steve Hanley There is news about Gigafactory 2 — Tesla’s solar factory near Buffalo, New York. First, Tesla has informed the Empire State Development Corporation, which owns the factory building and much of the equipment inside, that it has met […]
Fraunhofer ISE researchers have integrated stress and temperature sensors within a PV module. They claim that the devices cover a very minimal part of the cells, and that their interaction with the module and the cell itself is quite limited. The sensors can be manufactured as part of a regular cell manufacturing process. February 28, […]
Batteries Published on February 24th, 2020 | by Zachary Shahan February 24th, 2020 by Zachary Shahan Photo by Panasonic The most popular CleanTechnica stories last week involved perovskite solar cell research and projections (a hot topic for the past few — or several — years), Toyota’s continued focus on hybrids (considered by many to be […]
Trade body the Silver Institute says silver demand in the solar industry will dip slightly this year but remain near to previous record highs. Silver paste consumption for PV has been reduced due to advances in metallization techniques. February 13, 2020Emiliano Bellini PV manufacturers are reducing the amount of silver needed for metallization pastes. Image: […]
Saudi researchers have developed a cell which is said to exhibit improved structural and optoelectronic properties as well as enhanced carrier mobility and diffusion lengths. The feat was achieved by reducing voltage losses using a new passivation technique. February 12, 2020Emiliano Bellini The team from KAUST are helping turn conventional perovskite architecture on its head. […]
Clean Power Published on February 12th, 2020 | by Steve Hanley February 12th, 2020 by Steve Hanley In a series of tweets this week, Elon Musk said Tesla is ramping up the installation of its third-generation solar roof — called Solarglass Roof — in the San Francisco Bay Area, and it expects to announce availability […]
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. February 7, 2020Emiliano Bellini Scientists at South Korea’s […]
Australian researchers have unveiled hydrogenation technology to reduce light and elevated temperature-induced degradation in Czochralski silicon PERC solar cells. The developers say the process can minimize degradation without sacrificing performance in cells and modules. February 3, 2020Emiliano Bellini Scientists at the University of New South Wales Sydney have developed hydrogenation technology they say reduces light […]
Saudi researchers claim to have improved the thermal stability and moisture resistance of such devices by replacing 3D hybrid perovskite with two-dimensional compounds. They used organic compound ethanolamine, which is said to provide better results in slowing down the hot-carrier cooling process. January 24, 2020Emiliano Bellini The researchers have claimed another advance in shoring up […]
