Abstract
The present invention relates to a dye-sensitized solar cell unit (1) comprising: - a working electrode comprising a porous light-absorbing layer (10), - a porous first conductive layer (12) includingconductive material for extracting photo-generated electrons from the light-absorbing layer (10), - a porous insulating layer (105) made of an insulating material, - a counter electrode comprising aporous catalytic conductive layer (106) formed on the opposite side of the porous insulating layer (105), and - an ionic based electrolyte for transferring electrons from the counter electrode to theworking electrode and arranged in pores of the porous first conductive layer (12), the porous catalytic conductive layer (106), and the porous insulating layer (105), wherein the first conductive layer (12) comprises an insulating oxide layer (109) formed on the surfaces of the conductive material, and the porous catalytic conductive layer (106) comprises conductive material (107') and catalytic particles (107") distributed in the conductive material for improving the transfer of electrons from the conductive material (107") to the electrolyte.
Description
technical field [0001] The present invention relates to dye-sensitized solar cells. The invention also relates to a photovoltaic charger particularly suitable for charging electronic devices comprising dye-sensitized solar cells. Background technique [0002] Solar cells have long been used to convert light energy into electricity. Solar panels are used to absorb sunlight as an energy source to generate electricity. A solar panel includes a plurality of solar cells connected in series. In large solar parks, a large number of solar panels are often arranged together to produce electricity for the electricity supply network. [0003] The production of solar cells is becoming more efficient and cheaper. So, naturally, companies are making a wide variety of consumer products that are at least partially powered by solar cells. Today, many portable electronic devices are provided with a built-in rechargeable battery for storing energy, and a photovoltaic charger arranged to s...
