Thin-film solar startup HelioVolt has replaced its CEO B.J. Stanbery with one of its board members while it seeks a permanent chief executive.

The Austin-based company said Wednesday that Stanbery, who founded the company in 2001, will remain its chief strategy officer and chairman of the board. Ron Bernal, a board member and a partner at Sequel Venture Partners, will serve as the interim CEO.

HelioVolt, which just opened its first factory last October, also named Sanjeev Kumar as its chief financial officer. Kumar was the former CFO of Energy Conversion Devices.

The company is changing its head honcho at a time when it prepares to start its first-ever commercial production of solar panels made with copper, indium, gallium and selenium (CIGS).
