  • Replacement of Photovoltaic Cells with Organic Cells Using Chlorophyll

Abstract


There is great demand for energy as population increases. Renewable resources can be used to harness energy 60% of energy received by humans is from non-renewable resources. The main aim of the project is to increase the efficiency of the solar cell. The present solar cell is made of nonrenewable resources. They will have adverse effect on the environment. Solar energy has proven to be the effective way to harness energy till now. The PVC cells could be replaced by photosynthetic solar cell. Appropriate plant species for use in photosynthetic solar cell applications are those with high concentrations of chlorophyll alpha and chlorophyll beta . Green tea leaves (Camellia sinensis), broccoli leaves (Brassica italic), pimento fruits (Capsicum annum), carrots (Daucus carota), soybean seeds (Glycine max), alfalfa (Medicago sativa), purslane (Portulaca oleracea), and spinach (Spinacia oleracea) all have been found to contain high concentrations of chlorophyll alpha and beta . Many freshwater and marine species of algae also have high concentrations of chlorophyll .As chloroplast has the ability to absorb long wavelength it would be an efficient way to improve absorption and conservation of solar energy into usable energy. Chloroplast could be artificially cultivated by tissue-culture.

Objective


Our mission is to improve the absorption and conversion of sunlight into usable energy with renewable sources of materials.


Proposed Solution


The majority of current photosynthetic solar cells make use of non-renewable components. These materials can have an adverse effect on an environment. It is therefore vital to develop a non-toxic and renewable photosynthetic solar cell that can efficiently produce electricity. This project will attempt to demonstrate how to efficiently and sustainably utilize the living chlorophyll found in plant cells for electrical generation in a photosynthetic solar cell application. This can be accomplished by chemically extracting dense amount of chloroplasts from plants. The organic photosynthetic solar cells are synthesized in layers of chlorophyll, a catalyst, agarose, and a final layer of superconductive material known as graphene.


Impact of the proposed solution


Generation of energy using non-renewable resources will be reduced. If this happens all types of pollution will be reduced , we would be able to save our environment from destruction. Power shut downs would not be a problem if PSC’s is installed in all the houses. As all PSC’s are biodegradable we can reduce the accumulation of waste. Farmers will also be benefitted out of it as motors could be run using solar energy . Air pollution and water pollution can be reduced to an extent.
