Answer 2

In 2009, Samsung released the world's first solar-powered cell phone. It was known as the Samsung Guru E1107 and featured a solar cell built into its back plate. When exposed to sunlight, the cell generated electricity which in turn recharged the phone's battery. The small solar cell could not provide a lot of power, however. To generate the charge needed for a 5- to 10-minute voice call, the phone had to absorb an hour's worth of solar energy. Still, the solar charging feature made sense given the markets the phone was aimed at. The handset was designed for consumers living in developing markets and areas where power outages were a frequent occurrence.

Later in 2009, the company released the Samsung Blue Earth, which also featured a solar cell on its back - an hour of sunlight was converted into 10 additional minutes of talk time. Unlike the Guru, the Samsung Blue Earth offered a handful of advanced features, such as access to the web, YouTube, and social networks. It could connect to the internet over Wi-Fi or 3G, while a GPS radio enabled location services. Marketed as an eco-friendly product, the phone was built of recycled materials and came in a recycled cardboard box that doubled as a stand.

I am pretty certain Shunpei Yamazaki invented the solar mobile phone. Check his name out on YouTube. There is a four minute clip about him in Spanish, I cannot understand Spanish but I think the clip is about all of his inventions and the solar mobile phone pops up. The reason I answered this question is that I have a solar mobile phone!!
