Yes, that is why only a small sliver of the moon is visible from our vantage point on Earth during a new moon. When the moon is full, the Earth is now between the Sun and moon. In this configuration, we on Earth would now see the entire disk of the moon.
It's important to know the the sun is actually always illuminating one-half of the moon's orb 24/7. It only appears in "phases" because of our perspective from Earth.
At the "new" moon, the moon is between the Earth and the Sun. When it is on a direct line between the Earth and Sun, that new moon becomes a solar eclipse.
Between Earth and the Sun.
During the new moon the Moon is between the Earth an the Sun. Hence only the side that cannot be seen from Earth is illuminated, making the moon appear dark. During the full moon the Earth is between the Sun and the Moon so sunlight falls on the side of the moon facing the Earth, making it appear bright.
The moon is between the sun and earth and reflects light back toward the sun
During a new moon phase, the moon is between the sun and the earth. It usually passes not directly between the two, but above or even below. If the moon passes directly in front of the sun at this time, a solar eclipse occurs.

The moon is between the sun, and Earth and reflects light back toward the sun.

In a new moon, the moon is between Earth and the sun. They are nearly totally different. New Moon is solar eclipse season; not every New Moon gives a solar eclipse, but every solar eclipse happens at New Moon, without exception. The New Moon is when the moon is completely unlit from the point of view of observers on earth. During New Moon (not really visible to earth observers because the moon is blotted out by the blinding light of the sun) it is the night time side of the moon that is facing earth. Put another way, the face of the moon that is always oriented toward earth is experiencing its night time. During a lunar eclipse, that same face of the moon is darkened, but not because it is experiencing night time. The earth is between the moon and sun, and the earth's shadow darkens the face of the moon that we see. You could say that the entire surface of the moon is dark during a lunar eclipse. The far side is experiencing night time, and the earth side of the moon is darkened by earth's shadow. In a new moon, Earth is between the sun and the moon. ~ Apex
A solar eclipse happens.
Becausec the Moon is nearer the Sun than the Earth at New Moon.
They happen during, and only during, the new moon. This is because during an eclipse the moon has the sun shining from directly behind it, and it's impossible for us to see any of the side of the moon lit up by the sun from this angle.
