The present invention relates to a blind for electric photovoltaic power generation having an interior function and an emergency lighting function, and more particularly, to generate electric energy using a solar cell installed on a roll screen, In this case, the electric energy generated through the solar cell is used for blind driving power and battery charging power, and at the same time, it is transmitted to KEPCO and consumer loads, while the 220V AC power supplied from KEPCO is blindly driven when the amount of power generated by the solar cell is less than a set reference value. It relates to a blind for electric solar power generation having an interior function and an emergency lighting function for lighting the lighting means additionally installed in the present invention using the electric power and battery charging power, and using the electric power charged in the battery during a power outage.

Recently, as the environmental pollution problem has become serious due to the excessive use of fossil fuels, efforts are being made worldwide to reduce the use of fossil fuels.

To achieve this, a field in which continuous research and development is currently being conducted is an alternative energy or energy reduction technology using solar energy as a power source.

In general, solar cells produce electric energy using sunlight, which is an energy source, and so far, manufacturing of solar cells or modules has been the main concern.

In accordance with the current nuclear phase-out policy, not only the power plant business, which is a government-run construction project, but also the national policy project for individuals is implemented together, and the installation of solar cells in private houses and buildings is increasing every year.

In addition, attempts to graft a power generation system using solar energy into real life are increasing, and examples include a portable charging device using solar power generation or a blind using solar power generation.

Among them, the blind is fixedly installed on a window side of a house or office to protect personal privacy, control the amount of light, and is also used as a device for interior decoration.

A number of products related to photovoltaic power generation blinds implemented to produce electric energy using sunlight incident on the blinds during the day by using the characteristics of these blinds have been released, and a number of patents have also been applied and registered.

However, the previously released blinds using solar power could not automatically control the blinds using the AC power supplied from KEPCO using the automatic switching function when the amount of power generation of the solar cells was low. There was a problem that could not illuminate the surroundings.

On the other hand, as the prior art of the present invention, a "roll blind solar power generation system" of Patent Publication No. "10-2017-0008402" has been applied and registered. In the roll-type blind for blocking light, a thin film solar cell arranged on the light shielding film and made to be flexible to be wound like the light shielding film, and a storage battery connected to the thin film solar cell to store electrical energy obtained from the thin film solar cell, and a control unit connected between the thin film solar cell and the storage battery, wherein the control unit includes an overcharge prevention circuit for controlling a current value so that the storage battery is not overcharged.
