" the electrical potential of the cells can be restored on the exposure to direct sunlight after they have been discharged."

A Solar battery?

This is an exciting prospect, I will be researching this more

Your correct I just found this

Critical laboratory investigations show that what is
responsible for the sensitivity in Mimosa pudica leaves is
light absorption catalysis of oxidation reaction between
the chlorophyll b an oxidizing agent and thio-sulphite, a
reducing agent.
The tested electrical properties of Mimosa isolate
yielded 0.9V potential and 250mA DC current output.
Practical demonstration of the electrical potential of
Mimosa isolates (chlorophyll and thio-sulphite) was the
arrangement of cells in parallel which energized a LED
bulb. The accumulator is renewable after exhaustion and
takes only 30mins to attain full charge.
In all, the explored electrical potential of Mimosa
plant isolates has shown that it is possible to use Mimosa
pudica plant product to trap solar energy. This is a novel
attempt of making green electric power available.
The innovative exploration of the electrical potential
of mimosa plant for solar cell production is possible and
presents a novel way of making green electric power
available.

The aim of the research is to investigate the possibility of generating electricity from extract of Mimosa pudica leaves and to design a 'mimosa accumulator' to store the energy obtainable from the Mimosa pudica isolates. The leaves were dried in the oven, pulverized to enhance extraction with light petroleum and aqueous methanol. Fractions of chlorophyll a and b were separated. The second half of the pulverized leaves was placed in the muffle furnace to remove organic insulators. The ash was placed in sohxlet extraction unit and digested. The filtrate concentrated, purified and identified as thio-sulphite.Laboratory investigations show that light absorbed catalysis oxidation – reduction reaction between the chlorophyll, an oxidizing agent and thio-sulphite, a reducing agent. The challenges were how to utilize the electrons released by redox activity, and convert them to solar renewability. Hence, the isolates of chlorophyll b and thio-sulphite were mixed in three different ratios of 1:1, 1:2, and 2:1.    -----------   Using lead oxide and lead plates -----------.        2:1 mixture gave the highest value - 250mA output and 0.9V that lit an LED bulb. The innovative exploration of the electrical potential of mimosa plant for solar cell production is possible and presents a novel way of making green electric power available.

It also seems to be a book selling exercise:
