With the carbon-based organic solar cell or OSC, gleaming solar-paneled roofs atop commercial, residential, and industrial buildings might very well soon get a new look. OSCs may be a good alternative to conventional silicon-based cells due to their thinness and flexibility.
Around 750 million people do not have access to electricity at night. Solar cells deliver energy during the daytime, but storing it for later use necessitates substantial battery storage.
In a recent study published in the journal ACS Energy Letters, researchers from China reviewed the green process for producing sustainable perovskite solar cells (PSCs). They focused on the environmental and health impact of lead (Pb) and solvents used for manufacturing PSCs.
In a review article recently published in the open-access journal Sustainability, the researchers discussed the recent progress in the power generation, environmental aspects, market potential, and challenges of floating photovoltaics (PVs).
Tandem cells made of silicon and perovskite are able to convert the broad energy spectrum of sunlight into electrical energy more efficiently than the respective single cells. Now, for the first time, two teams from HZB and ISFH Hameln have succeeded in combining a perovskite top cell with a so-called PERC/POLO silicon cell to form a tandem device.
Solar photovoltaics (PV) is the main turning point in the shift toward a sustainable energy economy. The International Renewable Energy Agency (IRENA) roadmap proposes that by 2050, electricity production from PV should realize 43% of the total installed power capacity.
Displayed over roof tops and in solar farms, silicon-based solar cells are, so far, one of the most efficient systems in generating electricity from sunlight, but their fabrication can be expensive and energy demanding, aside from being heavy and bulky. The alternative solution of lower-cost thin film solar cells also brings the caveat of being mainly composed of toxic elements such as lead or cadmium, or containing scarce elements such as indium or tellurium.
Perovskite materials are low-cost, solution-processable semiconductors that can absorb and convert solar energy with extraordinarily high efficiencies, making them promising material for use in applications such as photovoltaic solar cells - if the material can be made stable and efficient.
In a recent study published in the journal Dyes and Pigments, researchers from the Republic of Korea developed a novel fluorine-based transparent and colorless ultraviolet (UV) light-harvesting dye for photovoltaic solar cells that can be fitted on to window glasses of urban buildings to meet the increasing energy demand for next decade.
All-polymer blend solar cells are expected to play an important role in the transition to clean energy technologies because they can be easily produced in large-scale flexible sheets. However, their performance has lagged behind that of more traditional silicon alternatives, as well as other organic solar cells.
