などに使用する太陽電池及び、これを使用した電子機器
の技術分野に関するものである。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a technical field of a solar cell used for a portable electronic device such as a portable telephone and a computer, especially a portable personal computer, and an electronic device using the same.
【０００２】[0002]

より一層電子機器の携帯性に対する要求も大きくなって
きている。2. Description of the Related Art The rapid advance of the information society in recent years has accelerated the spread of information electronic devices such as mobile phones and portable personal computers. For this reason, it was possible to collect and transmit information outdoors in the same environment as in the company,
Demands for portability of electronic devices have been increasing.
【０００３】この種の電子機器は、多機能さやコンパク

のものが搭載されている。従って、通常そのサイクルに
併せて充電作業を行う必要が生じる。In this type of electronic equipment, multifunctionality and compactness are important factors, but in addition to this, the duration of power supply when carrying is an important factor. For example, in a mobile phone, a so-called mobile phone call waiting time of usually 25 hours is mounted as a charging battery in consideration of a normal use situation. Therefore, it is usually necessary to perform the charging operation in accordance with the cycle.

For example, in the case of personal computers, measures have been taken to reduce the power consumption of hard disks, etc., or to install large-capacity lithium secondary batteries as storage batteries in order to achieve long-term use. ing.
【０００５】ところが、これらはそもそもこれら電子機
器の充電を室内での所謂商用電源からの充電を念頭とし
ているものであるため、電子機器が充電を必要とする時

を考慮しつつ利用する必要がある。[0005] However, since these electronic devices are charged with a so-called commercial power supply indoors in the first place, the time at which the electronic devices need to be charged is set at a location where commercial power is not available. It is necessary to use it while considering the time while you are outdoors.
【０００６】[0006]
【発明が解決しようとする課題】斯る対策として、これ
ら電子機器に電力として商用電源からの充電だけを利用
するのではなく、屋外などで太陽光を太陽電池によって
電気に変換し、これを電子機器の電力として利用するこ
とが提案されている。As a countermeasure, instead of using only charging from a commercial power source as electric power for these electronic devices, sunlight is converted to electricity by a solar cell outdoors or the like, and this is converted to electronic power. It has been proposed to use it as power for equipment.

ってしまっていた。However, since the amount of power generated by the solar cell is proportional to the area for receiving light, when the solar cell for power generation is mounted on the portable electronic device, the amount of power generated by the solar cell is smaller than that of the main electronic device. The size occupied by batteries has become larger, which has impaired the portability of electronic devices.
