Dr. Pearce received his Ph.D. atThe Pennsylvania State University,where his work onprotocrystallinityhelped develop low-costamorphous siliconsolar photovoltaictechnology.[2]His solar research and outreach[3]continues.[4][5]For example, his research group published alevelized cost of electricitystudy[6]on solar energy showed solar electricity was economically competitive with fossil fuels over wide geographic regions.[7][8]and showed the value of solar (VOS) often exceeds the net metering rate.[9][10]He showed 1% of Canada's agricultural land converted toagrivoltaicswould rid the national grid if carbon emissions while increasing food.[11]His research intoBDRFmodeling[12]of reflectors showed potential solar systems output increases of 30%.[13]His research supports solar canopies for parking lots,[14][15]floatovoltaics and aquavoltaics.[16]In addition he promotes theDIY[17]andmaker movements,[18]with the release ofTo Catch the Sunasopen access.[19]

He is also a vocal advocate of anopen-sourceapproach to technical development.[20]For his work related to open-sourcenanotechnology,[21]Ars Technicacompared him to Americansoftware freedomactivistRichard Stallman.[22]He applied open-source3-D printingand electronics toscientific equipmentdesign,[23]where he has claimed both superiorinnovationand lower costs.[24][25]Reviewing his bookOpen-Source Lab,3-D Printing Industrywrote, "This is a manual that every scientist should read and it holds a message so powerful and disruptive that theAnarchist Cookbookis a fairy tale in comparison. "[26]This work has extended to making frugal biomedical equipment and aids.[27][28][29]

His research has shown that printing household items with aRepRapis less costly[30]and better for the environment[31]than purchasing conventionally manufactured goods. Similarly, his group developed therecyclebot,a waste plastic extruder, which drops the cost of3D printing filamentfrom $35/kg to ten cents per kg while making recycling even more environmentally beneficial.[32][33]He also helped develop the concept of fused granular fabrication (FGF) where shredded waste plastic is directly converted to products.[34]

In 2013 his group released an open-source 3D printer capable of printing insteel,which cost less than US$1,200.[35][36]in order to encourage more rapid technological development according toScientific American.[37]This cost reduction was significant as theNew York Timesreported commercial metal printers at the time cost over US$500,000.[38]

He further developed inexpensive methods such asSODISto disinfect drinking water in thedeveloping world,using sunlight, water bottles, and salt.[39]He has called for corporate death penalties for industries that kill more people than they employ.[40]Recently, theMIT Sloan Management Reviewreported that Dr. Pearce has combined many of his research areas developing solar powered 3-D printers to drivesustainable development.[41]
