UNIV ARIZONA STATE [US]

WO_2020046915_PA

Absstract of: US2021376788A1

A self-powered voltage ramp for photovoltaic module testing provides a robust circuit for the measurement of current-voltage curves. A resistor and capacitor form a timer circuit to control a gate of a power transistor and give a linear voltage sweep from a short circuit (e.g., zero volts) to an open circuit voltage VOC. The sweep rate can be varied by adjusting the resistor value. Additional enhancements prevent oscillations within the circuit, maintain a voltage of the power transistor within its design specifications, and allow for the measurement of single cell mini-modules. Additional circuitry can characterize the photovoltaic module based on the measurement data. Measurement accuracy is within 1% of a laboratory supply for measurements of maximum power, short circuit current, and open circuit voltage.

SCALABLE, HIGHLY TRANSPARENT PAPER WITH MICROSIZED FIBER

Solar cell substrates require high optical transparency, but also prefer high optical haze to increase the light scattering and consequently the absorption in the active materials. Unfortunately, there is a tradeoff between these optical properties, which is exemplified by common transparent paper substrates exhibiting a transparency of about 90% yet a low optical haze (<20%). In this work we introduce a novel transparent paper made of wood fibers that display both ultra-high optical transparency ( ̃96%) and ultra-high haze ( ̃60%), thus delivering an optimal substrate design for solar cell devices. Compared to previously demonstrated nanopaper composed of wood-based cellulose nanofibers, our novel transparent paper has better dual performance in transmittance and haze, but also is fabricated at a much lower cost. This high-performance, low-cost transparent paper is a potentially revolutionary material that may influence a new generation of environmentally friendly printed electronics.

In order to maintain the temperature within a required temperature range, an internal temperature, an internal pressure, and a set of reservoir properties are monitored and then utilized to plot a phase diagram that can be used to detect liquid condensation. If liquid condensation is detected, an electrical output of the renewable energy source is adjusted in order to control the temperature of the subterranean hydrocarbon reservoir at a producing end of a production tubing.
