Major collaborative study predicts solar module efficiency could surpass 35% by 2050, driven by tandem cell technology (combining silicon with perovskites) and other innovations, potentially halving panel costs and extending lifespans to over 40 years, accelerating the global energy transition. This is part of a broader vision for multi-terawatt solar deployment, reducing emissions and land use.

Major collaborative study predicts solar module efficiency could surpass 35% by 2050, driven by tandem cell technology (combining silicon with perovskites) and other innovations, potentially halving panel costs and extending lifespans to over 40 years, accelerating the global energy transition. This is part of a broader vision for multi-terawatt solar deployment, reducing emissions and land use. 
Key Drivers & Projections:-
Tandem Cells: -
Combining different materials, like perovskites with silicon, allows cells to capture a wider spectrum of sunlight, boosting efficiency beyond what silicon alone can achieve.
Cost Reduction: -
Innovations in materials and manufacturing are expected to halve panel prices by 2050.
Longer Lifespans:-
 Solar hardware is anticipated to last over 40 years, improving sustainability.
Multi-Terawatt Scale: -
The industry is preparing for massive growth, with projections for manufacturing capacity reaching 3 TW. 
Research & Collaboration:-
This outlook comes from leading institutions like Germany's Fraunhofer ISE, the U.S. National Renewable Energy Laboratory (NREL), and Japan's AIST, published in Nature Energy. 
Implications:-
Reduced Land Use: -
Higher efficiency means less area is needed for large solar farms.
Accelerated Energy Transition:-
 Increased performance and lower costs make solar a more powerful tool for decarbonization.

Solar Generation in Night hrs

How to get get Solar generations in Night        While standard solar panels cannot generate electricity at night,     New technologies are being developed to address this limitation.      These advancements focus on harnessing the earth's heat or using infrared radiation emitted by the Earth to generate power, potentially creating 24-hour renewable energy sources.  Key Concepts and Technologies :- 1) Anti-Solar Panels (Thermo-radiative Cells):- How they work:-    These panels, also known as thermoradiative cells, work in reverse of traditional solar panels. Instead of absorbing sunlight, they emit infrared radiation into space, which is then converted into electricity.    Nighttime energy:-     They can generate electricity from the difference in temperature between the panel and the surrounding environment, essentially converting the heat escaping into space back into usable power.  Potential:-  ...

Hydrogen at home — It's the end of solar and wind power

  Hydrogen at home — It's the end of solar and wind power         Statement "1000 pounds" per day of hydrogen at home — It's the end of solar and wind power in the world" is not accurate.     While hydrogen can be produced from renewable energy sources like solar and wind power, it's not a replacement for those sources themselves. Hydrogen production via electrolysis, using renewable electricity, is a promising avenue for decarbonization, but it doesn't negate the need for solar and wind power as direct energy sources.  Cause behind its is as under. Hydrogen as an Energy Carrier:-     Hydrogen is an energy carrier, meaning it stores energy produced elsewhere (like from solar or wind) and can be used to power fuel cells or for other applications.  Electrolysis:-     A key method of producing "green" hydrogen involves using electricity from renewable sources (like solar and wind) to split water into hydrogen and oxygen throu...
