Title:
PHOTOVOLTAIC ELEMENT AND SOLAR CELL
Document Type and Number:
WIPO Patent Application WO/2010/067718
Kind Code:
A1
Abstract:
Provided are photovoltaic elements that are equipped with an n-i-p structure formed with amorphous silicon and with which energy conversion efficiency is improved by a structure wherein an n+-type a-Si layer contacts a transparent electrode formed by an n+-type ZnO layer. The impact on global resources is thereby kept to a minimum, and photovoltaic elements and solar batteries with large surface area and high power output can be realized.
