Coupling of technology with sustainability has led to many smartphones and accessories that are an ideal choice for all eco-friendly people. A major drain to the global level of power is the electricity drawn by our smartphones for charging. Solar-powered smartphones are the solution to eliminate this electricity demand and still enjoy cutting edge technology.

Photovoltaic cells behind the display screen

ArmanAhnood has created photovoltaic cells that are of the thickness of an OLED or LCD display and bonded this layer of solar cells to the stack of films that together form the display of the mobile screens. This sandwiching of the solar cells behind the display enables the overhead lights or solar energy to be harvested by the phones. Currently, this system has an efficiency of 11% and can generate a total output of about five milliwatts for a typical 3.7-inch touchscreen. The team is working on increasing the system’s efficiency and output.

Micromax X259



Indian mobile phone giant Micromax has created this solar-powered phone that is also the cheapest cell phone available in the market. The device comes with a 2.5-inch coloured display, 0.3MP primary camera, dual SIM slots, and Bluetooth connectivity. The battery door is covered with built-in solar panels which can offer a battery backup of 1.5hours after 3 hours of sunshine exposure.

Samsung’s Blue Earth


Samsung has created what might be the greenest smartphone currently available in the market. With Blue Earth, Samsung has introduced full solar panels in the back to generate solar powered energy for charging the phone.

The body of the phone is made out of recycled water bottles and many toxic chemicals like brominated flame retardants, beryllium, and phthalates have been avoided completely during manufacturing. The company uses minimal packaging made by recycling paper. The phone has a built-in pedometer, CO2 emissions calculator, and an interface to enable power-saving mode when the user wants to.

Puma Phone


Created by Sagem, this phone is rich in features. The fullsolar panel back allows easy and quick charging by harnessing solar radiations. The design resembles the Samsung Blue Earth phone but Puma has provided a 2.8-inch touchscreen display, 3.2MP primary and secondary cameras, pedometer, stopwatch, GPS tracker, and a compass.

Kyocera’s solar powered phone


The Japanese cell phone maker Kyocera has released a newer version of its currently nameless solar-powered cell phone, which is a big improvement over its last year’s model. The new prototype is a 12.7-centimeter that provides a minute of talk time for every three minutes of solar charging.

The phone was developed by Kyocera in partnership with the France-based Sunpartner Technologies, who have created a translucent film that is impregnated with photovoltaic cells. This film can be placed between the LCD display and the touch screen to allow easy charging during use. Kyocera is working on making this phone more efficient and expects to release it into the market by next year.



LG has entered the solar-energy driven mobile phone market with its latest solar-powered mobile, the GD510 POP. The phone has an 8GB SD card on board and has a 3-inch touchscreen. The back is covered with solar panels for easily charging the phone when it is kept face down. The rear camera is 3MP and is an efficient shooter for a sustainable gadget.

Sustainable technology has made leaps in creating eco-friendly gadgets and the pioneers in this industry are the solar powered smartphones. Many companies are working on creating efficient smartphones that can power the phone’s functionalities by adding photovoltaic cells and solar panels on the structure.
