• Micromax launches solar handset in India

    January 8, 2019 admin news

    Micromax, one of the largest Indian mobile phone brands, plans to launch a phone with a built-in solar charger. The handset, to be released shortly, will charge in 3 hours to support 1.5 hours of talktime, and uses Intivation’s SunBoost3 technology to supply the best possible solar charge.

    Rahul Sharma, co-founder and executive director, Micromax, says:

    We have been at the forefront of innovation. We were the first to launch long battery life phones, dual SIM phones and many more. Our next innovation is to get rid of the mobile phone charger by including a solar panel in our next phone.

  • Mobile World Congress 2012

    Intivation will be present once more at the GSMA’s Mobile World Congress in Barcelona, held from 27 February to 1 March at the Fira de Barcelona.

    We will exhibit, together with our partners Q-Mo Solar and A-Solar, at booth 1F53, where just like every year we will showcase the latest innovations built with our technology.

    Here are a few highlights from last year’s event:

  • Solar cell with 100% efficiency

    December 19, 2011 admin news

    Engadget reports today that scientists have discovered a way to produce solar cells that can capture 100% of the energy contained in the sunlight that reached them:

    Researchers over at the National Renewable Energy Lab have reportedly made the first solar cell with an external quantum efficiency over 100 percent. Quantum efficiency relates to the number of electrons-per-second flowing in a solar cell circuit, divided by the number of photons from the energy entering. The NREL team recorded an efficiency topping out at 114 percent, by creating the first working multiple exciton generation (MEG) cell. Using MEG, a single high energy photon can produce more than one electron-hole pair per absorbed photon. The extra efficiency comes from quantum dots ‘harvesting’ energy that would otherwise be lost as heat. The cell itself uses anti-reflection coating on a transparent conductor, layered with zinc oxide, lead selenide, and gold. NREL scientist Arthur J. Nozik predicted as far back as 2001 that MEG would do the job, but it’s taken until now for the concept to leap over from theory.

    From the original article:

    Multiple exciton generation (MEG) is a process that can occur in semiconductor nanocrystals, or quantum dots (QDs), whereby absorption of a photon bearing at least twice the bandgap energy produces two or more electron-hole pairs. Here, we report on photocurrent enhancement arising from MEG in lead selenide (PbSe) QD-based solar cells, as manifested by an external quantum efficiency (the spectrally resolved ratio of collected charge carriers to incident photons) that peaked at 114 ± 1% in the best device measured. The associated internal quantum efficiency (corrected for reflection and absorption losses) was 130%. We compare our results with transient absorption measurements of MEG in isolated PbSe QDs and find reasonable agreement. Our findings demonstrate that MEG charge carriers can be collected in suitably designed QD solar cells, providing ample incentive to better understand MEG within isolated and coupled QDs as a research path to enhancing the efficiency of solar light harvesting technologies.

  • Increased battery life #1 desire

    March 25, 2011 admin news

    The Mobile Indian published a striking result of a recent poll organised by Nokia to determine user’s preferences for an affordable phone to reach ‘the next billion’, one of the big themes is telecommunications:

    Just a fraction under 20 per cent of the total people, who took part in the Nokia’s poll for the ‘Next Billion’, wants their phone to have a longer battery life followed closely by Internet access with 11 per cent people opting for it.

    The sole purpose of the survey, according to Nokia, was to know what the mobile users expect from a smart yet affordable device.

    Of course Intivation strongly subscribes to this notion. Especially in the emerging regions, where most of ‘the next billion’ will be found, electricity is a huge issue. While mobile networks are generally available, powered by solar and diesel, it’s cumbersome and even expensive to charge a cellphone in places where electricity is not readily available.

    With the recent launch of our latest technology, we have brought embedded solar power to a new level, and we expect to see more and more handset manufacturers to adopt solar technology (hopefully with our help) – especially since more and more users are indicating that more power is a key issue for them.

    Solar powered phones solve the electricity issue in a very elegant and user-friendly way: it’s the most convenient and cheap way to charge a mobile phone. And as the phones are increasingly used to access the internet, the need for electricity in the device will only grow.
